Laser Cutter

2015-02-01T03:52:13Z

Bmanifold: /* Cutting/Engraving Material Suppliers */

[[File:lasercutter.jpeg|350px|right|thumb|Our Homemade Laser Cutter|alt=Our Homemade Laser Cutter]]

We have a [http://www.buildlog.net/blog/2011/02/buildlog-net-2-x-laser/ Buildog.net 2.x Laser] on site at Knox Makers. It is capable of cutting, engraving, and marking a number of different materials quickly and accurately when driven from CAD software such as Inkscape.

== Buildlog 2.x Laser ==
'''''See Also: [[Laser Hardware]]'''''

The Buildlog.net 2.x Laser is an open source laser cutter/engraver. The usable work envelope is approximately 260mm x 500mm x 100mm. The machine uses a 40W CO2 infrared laser to engrave/cut. Detailed information on it's operation is provided below, but the general theory of operation is as follows. Inside the laser cutter there is a very powerful CO2 infrared laser that is bounced off of a few mirrors and is finally directed towards the material being cut or etched by a moving mirror and lens that focuses the coherent beam. These mirrors and lenses are gold coated to provide the best possible transmission of infrared energy.

There are two main variables that the laser uses to cut and etch: speed and power. When cutting, the laser power is increased and the speed is decreased so that the cutting beam spends a longer time hitting the material in order to cut though. While etching the speed is increased and/or the power reduced, this way the laser only removes a little material from the surface, leaving just the etching.

== Usage ==
You must take the [[Laser Operation Class]] in order to have permission to use the laser cutter. The laser cutter is a very powerful, but also easy to break machine that requires some training to be able to use effectively and safely. Once you have taken the class, you will be added to the [https://docs.google.com/spreadsheets/d/1dGRW5Dh4zC9mhChBooV--RfmehFxs9Sdpk9r0sWa6_8/edit?usp=sharing Knox Makers Laser Cutter Checkout List].

At this time, we do not plan to schedule the usage of the laser cutter. If usage is heavier than anticipated, we reserve the right to institute a scheduling system to be fair to other users.

When you arrive at the space, remember to sign in and sign out on the log sheet. Please note any damage or issues with the laser when you sign in.

== Materials ==
There are a wide range of materials that the Laser Cutter can cut, etch or mark - but some simply don't work (eg metals) and some are extremely hazardous to either humans or the machine itself. It is therefore imperative that you check the list of [[Laser Cutter Materials]] before attempting to cut materials that you have not worked with before.

== Laser Cutter Settings ==
There has been some preliminary testing with common materials to generate a set of recommended values for speed and laser power: [[Laser Cutter Settings]]. These values have been included as defaults into our laser cutter Inkscape plug-in. The values should be acceptable for the listed materials, and can serve as a starting point for testing for other materials. The laser settings are internally limited to prevent damaging the laser, so feel free to experiment.

Beyond changing speed and laser power, do not attempt to change the configuration of the laser cutter. These settings are calibrated regularly by our Laser Cutting [[SME]] and are not intended for users to change. Doing this messes up other people's work and it's NOT COOL. As with everything in the space, when you're done, leave things better than they were when you started. Changing settings could mean the laser is not right when the next person comes to use the machine.

== Manuals ==
Editor's Note: Do we have anything that goes in here?

== Theory: How it Works ==
Inside the laser cutter there is a very powerful CO2 infrared laser that is bounced off of a few mirrors onto a moving head and is finally directed towards the material being cut or etched by a moving mirror and lens that focuses the coherent beam. These mirrors and lenses are gold coated to provide the best possible transmission of infrared energy.

The infrared (IR) light that the laser cutter produces would blind you instantly if you were to look directly at it - and it's so bright that even you were only looking at the light reflected off the material that's being cut, it could still blind you. The IR light is also totally invisible. Fortunately, IR light doesn't pass easily through the window of the cutter that is made of a Polycarbonate plastic (which strongly absorbs light in those wavelengths). For this reason, if the lid (and the front panel) of the laser are not properly shut, then the IR laser will turn off automatically. The intense white light that you sometimes see when the cutter is operating is actually visible light that's being emitted by the material that the laser is burning off (it's literally 'white hot'!).

For carbon-based (organic) materials (like wood, paper, cloth and leather), you see the material being burned away and there may be black residue left behind. For plastics like Acrylic, the material is chemically decomposed by the laser and you don't see that white hot trail as it cuts. However, when the laser hits the metal grid beneath the material, there will still be bright flashes of light from that.

== Making drawings for the Laser Cutter ==
'''''See Also: [[Using Inkscape with the Laser Cutter]]'''''

The recommended software path is to design your drawing in Inkscape, use the KMLaser bundle to export your drawing into gcode, then import the gcode to LinuxCNC which drives our laser cutter.

However, these are only conventions. The only requirements is that your design ends in gcode that is understood by our configuration of LinuxCNC. [[Laser Cutter Settings]] is a good reference with explanations of the values you will need to set in your gcode.

Bmanifold: /* Coping files */

This page discusses information related to the proper usage of the computer controlling the laser cutter.
==Network Access==
The name of the computer that controls the laser cutter is "goldfinger". It is accessible over the network using this name. The default user account is "jamesbond". This means that the computer is accessible using the credentials "jamesbond@goldfinger".

==Copying files==
Files can be copied to the computer in a few ways. There is a directory on the desktop named "Gcode". You should make a directory in "Gcode" using your name or other unique identifier and copy your Gcode files to that location. Using a USB memory card in the computer is an option. Using the command line, files can be copied using the "scp" command. Example below:

scp <file name on your computer> jamesbond@goldfinger:/Desktop/Gcode/<unique folder name>

In Ubuntu, you can connect to the computer from your file browser. Click the "Connect to Server" option under the "Network" heading on the left tab. Use the address:

sftp://jamesbond@goldfinger/home/Desktop/Gcode/<unique folder name>

You can connect directly to your folder on the Goldfinger computer that way. You can add this place to your bookmarks, and have it immediately available to you anytime you are connected to our network.

Using Inkscape with the Laser Cutter

2014-12-29T05:43:16Z

Bmanifold:

This page should be a tutorial on how to use our Inkscape Plugin, with screen shots, directions, caveats, etc.

Link back to [[Laser Cutter]].

==Inkscape Basics==
* The first thing you will need to do is create/download a design in Inkscape.
** [https://www.youtube.com/results?search_query=inkscape+tutorials Youtube Inkscape Tutorials]

* Once you have created your design you'll want to make sure all your objects are paths so all your extensions will work with them. You can do CTRL+A to select everything then use the method in the video.
<youtube>dxTmhtvMNoo</youtube>

* You'll also need to either move your design to X = 0, Y = 0 or resize the document to match your design (which essentially moves it to X = 0, Y = 0). This way you can more accurately predict where the laser will start cutting.
<youtube>Zv7N2yBfSFA</youtube>
<youtube>gw6DDrSgjog</youtube>

*From time to time you'll end up with designs in the (root) layer instead of an actual named layer. You'll need to fix this before turning your design to gcode. You can just cut and paste it into an actual layer as the video shows. Once there is nothing in the (root) it will go away.
<youtube>RypRpm81QiY</youtube>

* Setting the stroke color of the paths you want to cut/engrave will be important when you want different laser settings in one design (both engrave and cut for example).
<youtube>o9fBSIwVvGs</youtube>

* Sizing your designs to the desired size will be important. Here is a video on how to do that while keeping everything aligned and keeping the aspect ratio.
<youtube>m8iAdZxmLXI</youtube>

==KMLaser Bundle==
We've put together a bundle of Inkscape extensions that you might find useful. You can download the bundle at [https://github.com/KnoxMakers/KM-Laser our github].

==Path to Gcode==
This extension is the work horse for the bundle. It takes the paths from your design and turns them into gcode required to run our laser cutter. This extension is based on part of [http://www.cnc-club.ru/forum/viewtopic.php?t=35 Gcodetools] but has been heavily altered for our purposes.

Here's a video showing how to set up the file options the first time you use Path to Gcode:

<youtube>2WTO7oB30-4</youtube>

This extension lets you use different stroke colors to represent different laser powers (cut, engrave(heavy), engrave(light)). Here's a video showing the use of the By Color presets option:

<youtube>XYkYeYYVZeM</youtube>

When using the By Color option the following stroke colors translate to the labeled actions:

{| cellspacing="0" cellpadding="5" border="1"
!Color
!Action
|-
|#000000
|Cut
|-
|#ff0000
|Cut
|-
|#0000ff
|Engrave (Heavy)
|-
|#00ffff
|Engrave (Light)
|}

'''NOTICE: When setting the hex values in Inkscape, the value is actually RGBA which has an alpha (opacity) value at the end so you will need to add an ff to the end of the values above.
'''

==Hatch Fill==
This extension allows you to fill in any closed figure in your design with lines or crossed lines. This is useful when you want to engrave an entire area within your design. This extension is based on part of the [https://code.google.com/p/eggbotcode/downloads/ eggbot] extensions.

Here's a quick video on how to use it:

<youtube>qdIjZXzT-QE</youtube>

==Hershey Text==
Hershey Text produces single-stroke text that is appropriate for cnc engraving or plotters. This extension is based on part of the [https://code.google.com/p/eggbotcode/downloads/ eggbot] extensions.

Here is a quick video on the difference between it and Inkscape fonts:

==Tabbed Box Maker==
This extension creates the paths necessary to cut out tabbed boxes. This extension is based of the extension you can find [http://www.keppel.demon.co.uk/111000/111000.html here].

Here's a quick video on how to use it:

Laser Cutter

2014-12-05T16:03:34Z

Bmanifold:

[[File:lasercutter.jpeg|350px|right|thumb|Our Homemade Laser Cutter|alt=Our Homemade Laser Cutter]]

We have a [http://www.buildlog.net/blog/2011/02/buildlog-net-2-x-laser/ Buildog.net 2.x Laser] on site at Knox Makers. It is capable of cutting, engraving, and marking a number of different materials quickly and accurately when driven from CAD software such as Inkscape.

== Buildlog 2.x Laser ==
'''''See Also: [[Laser Hardware]]'''''

The Buildlog.net 2.x Laser is an open source laser cutter/engraver. The usable work envelope is approximately 260mm x 500mm x 100mm. The machine uses a 40W CO2 infrared laser to engrave/cut. Detailed information on it's operation is provided below, but the general theory of operation is as follows. Inside the laser cutter there is a very powerful CO2 infrared laser that is bounced off of a few mirrors and is finally directed towards the material being cut or etched by a moving mirror and lens that focuses the coherent beam. These mirrors and lenses are gold coated to provide the best possible transmission of infrared energy.

There are two main variables that the laser uses to cut and etch: speed and power. When cutting, the laser power is increased and the speed is decreased so that the cutting beam spends a longer time hitting the material in order to cut though. While etching the speed is increased and/or the power reduced, this way the laser only removes a little material from the surface, leaving just the etching.

== Usage ==
You must take the [[Laser Operation Class]] in order to have permission to use the laser cutter. The laser cutter is a very powerful, but also easy to break machine that requires some training to be able to use effectively and safely. Once you have taken the class, you will be added to the [https://docs.google.com/spreadsheets/d/1dGRW5Dh4zC9mhChBooV--RfmehFxs9Sdpk9r0sWa6_8/edit?usp=sharing Knox Makers Laser Cutter Checkout List].

At this time, we do not plan to schedule the usage of the laser cutter. If usage is heavier than anticipated, we reserve the right to institute a scheduling system to be fair to other users.

When you arrive at the space, remember to sign in and sign out on the log sheet. Please note any damage or issues with the laser when you sign in.

== Materials ==
There are a wide range of materials that the Laser Cutter can cut, etch or mark - but some simply don't work (eg metals) and some are extremely hazardous to either humans or the machine itself. It is therefore imperative that you check the list of [[Laser Cutter Materials]] before attempting to cut materials that you have not worked with before.

== Laser Cutter Settings ==
There has been some preliminary testing with common materials to generate a set of recommended values for speed and laser power: [[Laser Cutter Settings]]. These values have been included as defaults into our laser cutter Inkscape plug-in. The values should be acceptable for the listed materials, and can serve as a starting point for testing for other materials. The laser settings are internally limited to prevent damaging the laser, so feel free to experiment.

Beyond changing speed and laser power, do not attempt to change the configuration of the laser cutter. These settings are calibrated regularly by our Laser Cutting [[SME]] and are not intended for users to change. Doing this messes up other people's work and it's NOT COOL. As with everything in the space, when you're done, leave things better than they were when you started. Changing settings could mean the laser is not right when the next person comes to use the machine.

== Manuals ==
Editor's Note: Do we have anything that goes in here?

== Theory: How it Works ==
Inside the laser cutter there is a very powerful CO2 infrared laser that is bounced off of a few mirrors onto a moving head and is finally directed towards the material being cut or etched by a moving mirror and lens that focuses the coherent beam. These mirrors and lenses are gold coated to provide the best possible transmission of infrared energy.

The infrared (IR) light that the laser cutter produces would blind you instantly if you were to look directly at it - and it's so bright that even you were only looking at the light reflected off the material that's being cut, it could still blind you. The IR light is also totally invisible. Fortunately, IR light doesn't pass easily through the window of the cutter that is made of a Polycarbonate plastic (which strongly absorbs light in those wavelengths). For this reason, if the lid (and the front panel) of the laser are not properly shut, then the IR laser will turn off automatically. The intense white light that you sometimes see when the cutter is operating is actually visible light that's being emitted by the material that the laser is burning off (it's literally 'white hot'!).

For carbon-based (organic) materials (like wood, paper, cloth and leather), you see the material being burned away and there may be black residue left behind. For plastics like Acrylic, the material is chemically decomposed by the laser and you don't see that white hot trail as it cuts. However, when the laser hits the metal grid beneath the material, there will still be bright flashes of light from that.

== Making drawings for the Laser Cutter ==
'''''See Also: [[Using Inkscape with the Laser Cutter]]'''''

The recommended software path is to design your drawing in Inkscape, use the KMLaser bundle to export your drawing into gcode, then import the gcode to LinuxCNC which drives our laser cutter.

However, these are only conventions. The only requirements is that your design ends in gcode that is understood by our configuration of LinuxCNC. [[Laser Cutter Settings]] is a good reference with explanations of the values you will need to set in your gcode.

Laser Cutter

2014-12-05T15:07:36Z

Bmanifold: /* Software Tools */

[[File:lasercutter.jpeg|frame|right|x350px|Our homemade laser cutter.|alt=Our homemade laser cutter.]]

We have a [http://www.buildlog.net/blog/2011/02/buildlog-net-2-x-laser/ Buildog.net 2.x Laser] on site at Knox Makers. It is capable of cutting, engraving, and marking a number of different materials quickly and accurately when driven from CAD software such as Inkscape.

== Buildlog 2.x Laser ==
'''''See Also: [[Laser Hardware]]'''''

The Buildlog.net 2.x Laser is an open source laser cutter/engraver. The usable work envelope is approximately 260mm x 500mm x 100mm. The machine uses a 40W CO2 infrared laser to engrave/cut. Detailed information on it's operation is provided below, but the general theory of operation is as follows. Inside the laser cutter there is a very powerful CO2 infrared laser that is bounced off of a few mirrors and is finally directed towards the material being cut or etched by a moving mirror and lens that focuses the coherent beam. These mirrors and lenses are gold coated to provide the best possible transmission of infrared energy.

There are two main variables that the laser uses to cut and etch: speed and power. When cutting, the laser power is increased and the speed is decreased so that the cutting beam spends a longer time hitting the material in order to cut though. While etching the speed is increased and/or the power reduced, this way the laser only removes a little material from the surface, leaving just the etching.

== Usage ==
You must take the [[Laser Operation Class]] in order to have permission to use the laser cutter. The laser cutter is a very powerful, but also easy to break machine that requires some training to be able to use effectively and safely. Once you have taken the class, you will be added to the [https://docs.google.com/spreadsheets/d/1dGRW5Dh4zC9mhChBooV--RfmehFxs9Sdpk9r0sWa6_8/edit?usp=sharing Knox Makers Laser Cutter Checkout List].

At this time, we do not plan to schedule the usage of the laser cutter. If usage is heavier than anticipated, we reserve the right to institute a scheduling system to be fair to other users.

When you arrive at the space, remember to sign in and sign out on the log sheet. Please note any damage or issues with the laser when you sign in.

== Materials ==
There are a wide range of materials that the Laser Cutter can cut, etch or mark - but some simply don't work (eg metals) and some are extremely hazardous to either humans or the machine itself. It is therefore imperative that you check the list of [[Laser Cutter Materials]] before attempting to cut materials that you have not worked with before.

== Laser Cutter Settings ==
There has been some preliminary testing with common materials to generate a set of recommended values for speed and laser power: [[Laser Cutter Settings]]. These values have been included as defaults into our laser cutter Inkscape plug-in. The values should be acceptable for the listed materials, and can serve as a starting point for testing for other materials. The laser settings are internally limited to prevent damaging the laser, so feel free to experiment.

Beyond changing speed and laser power, do not attempt to change the configuration of the laser cutter. These settings are calibrated regularly by our Laser Cutting [[SME]] and are not intended for users to change. Doing this messes up other people's work and it's NOT COOL. As with everything in the space, when you're done, leave things better than they were when you started. Changing settings could mean the laser is not right when the next person comes to use the machine.

== Manuals ==
Editor's Note: Do we have anything that goes in here?

===Prerequisites===
Basic electronic theory will be helpful, but not required.

===Further Information===
The basic class provides an overview of the machine itself, what materials you can and can't use, and basics of operation.

You will be provided 3 12x12" (roughly) pieces of material: poster paper, plywood, and acrylic. The poster paper and acrylic are utilized in two exercises during class time, and the wood is left for you to experiment with on your own.

Using Inkscape with the Laser Cutter

2014-10-13T15:22:11Z

Bmanifold:

This page should be a tutorial on how to use our Inkscape Plugin, with screen shots, directions, caveats, etc.

Link back to [[Laser Cutter]].

==Inkscape Basics==
* The first thing you will need to do is create/download a design in Inkscape.
** [https://www.youtube.com/results?search_query=inkscape+tutorials Youtube Inkscape Tutorials]

* Once you have created your design you'll want to make sure all your objects are paths so all your extensions will work with them. You can do CTRL+A to select everything then use the method in the video.
**[http://youtu.be/dxTmhtvMNoo Make sure your objects are paths.]

* You'll also need to either move your design to X = 0, Y = 0 or resize the document to match your design (which essentially moves it to X = 0, Y = 0). This way you can more accurately predict where the laser will start cutting.
**[http://youtu.be/Zv7N2yBfSFA Resize your document to match your design.]
**[http://youtu.be/gw6DDrSgjog Move your design to X=0, Y=0]

*From time to time you'll end up with designs in the (root) layer instead of an actual named layer. You'll need to fix this before turning your design to gcode. You can just cut and paste it into an actual layer as the video shows. Once there is nothing in the (root) it will go away.
**[http://youtu.be/RypRpm81QiY Fix designs with (root) layers]

* Setting the stroke color of the paths you want to cut/engrave will be important when you want different laser settings in one design (both engrave and cut for example).
**[http://youtu.be/o9fBSIwVvGs Setting the stroke color]

* Sizing your designs to the desired size will be important. Here is a video on how to do that while keeping everything aligned and keeping the aspect ratio.
**[http://youtu.be/m8iAdZxmLXI Resizing your Design]

==KMLaser Bundle==
We've put together a bundle of Inkscape extensions that you might find useful. You can download the bundle at [https://github.com/KnoxMakers/KM-Laser our github].

==Path to Gcode==
This extension is the work horse for the bundle. It takes the paths from your design and turns them into gcode required to run our laser cutter. This extension is based on part of [http://www.cnc-club.ru/forum/viewtopic.php?t=35 Gcodetools] but has been heavily altered for our purposes.

Here's a video showing how to set up the file options the first time you use Path to Gcode:

[http://youtu.be/2WTO7oB30-4 KMLaser: Path to Gcode File Options]

This extension lets you use different stroke colors to represent different laser powers (cut, engrave(heavy), engrave(light)). Here's a video showing the use of the By Color presets option:

Lasercutting

2014-10-13T15:04:25Z

Bmanifold:

There are a wide range of materials that the [[Laser Cutter]] can cut, etch or mark - but some simply don't work (eg metals) and some are extremely hazardous to either humans or the machine itself (eg PVC and ABS). It is therefore imperative that you check these lists before attempting to cut materials that you have not worked with before.

It is not always obvious which materials will work - for example: Polycarbonate/Lexan produces flames and doesn't burn well, or even etch without lots of soot and yellowing. Yet Acrylic - which looks, smells, feels and tastes just like Lexan - cuts smoothly and cleanly and is one of the best materials to use with the laser! So check and double-check what you're cutting.

== Where to Find Materials ==

There are some materials at the hackerspace, but in limited quantities. If you need larger quantities or a unique material, you can try one of the places listed here:

* The big chain hardware stores will have a few options for 3mm/6mm plywoods and clear acrylic.
* [https://www.facebook.com/pages/Jeffries-Wood-Works/446121655478402?sk=info&ref=page_internal Jeffries Wood Works] is a great local wood supplier.

== NEVER CUT THESE MATERIALS ==

'''WARNING''': Because many plastics are dangerous to cut, it is important to know what kind you are planning to use. Make has a How-To for identifying unknown plastics with [http://blog.makezine.com/archive/2011/09/identifying-unknown-plastics.html?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+makezineonline+%28MAKE%29&utm_content=Google+Reader a simple process].

{| cellspacing="0" cellpadding="5" border="1" align="center"
|-
! Material
! DANGER!
! Cause/Consequence
|-
| PVC (Poly Vinyl Chloride)/vinyl/pleather/artificial leather
| Emits pure chlorine gas when cut!
| Don't ever cut this material as it will ruin the optics, cause the metal of the machine to corrode, and ruin the motion control system.
|-
| Thick ( >1mm ) Polycarbonate/Lexan
| Cut very poorly, discolor, catch fire
| Polycarbonate is often found as flat, sheet material. The window of the laser cutter is made of Polycarbonate because ''polycarbonate strongly absorbs infrared radiation!'' This is the frequency of light the laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Polycarbonate is a poor choice for laser cutting.
|-
| ABS
| Emits cyanide gas and tends to melt
| ABS does not cut well in a laser cutter. It tends to melt rather than vaporize, and has a higher chance of catching on fire and leaving behind melted gooey deposits on the vector cutting grid. It also does not engrave well (again, tends to melt).
|-
| HDPE/milk bottle plastic
| Catches fire and melts
| It melts. It gets gooey. Don't use it.
|-
| PolyStyrene Foam
| Catches fire
| It catches fire, it melts, and only thin pieces cut. This is the #1 material that causes laser fires!!!
|-
| PolyPropylene Foam
| Catches fire
| Like PolyStyrene, it melts, catches fire, and the melted drops continue to burn and turn into rock-hard drips and pebbles.
|-
| Fiberglass
| Emits fumes
| It's a mix of two materials that cant' be cut. Glass (etch, no cut) and epoxy resin (fumes)
|-
| Coated Carbon Fiber
| Emits noxious fumes
| A mix of two materials. Thin carbon fiber mat can be cut, with some fraying - but not when coated.
|}

== Safe Materials ==

The laser can cut or etch. The materials that the laser can cut materials like wood, paper, cork, and some kinds of plastics. Etching can be done on almost anything wood, cardboard, plastic, marble, stone, and tile.

=== Cutting ===

{| cellspacing="0" cellpadding="5" border="1" align="center"
|-
! Material
! Max thickness
! Notes
! WARNINGS!
|-
| Many woods
| 1/4"
| Avoid oily/resinous woods
| Be very careful about cutting oily woods, or very resinous woods as they also may catch fire.
|-
| Plywood/Composite woods
| 1/4"
| These contain glue, and may not laser cut as well as solid wood.
|
|-
| MDF/Engineered woods
| 1/4"
| These are okay to use but may experience a higher amount of charring when cut.
|
|-
| Paper, card stock
| thin
| Cuts very well on the laser cutter, and also very quickly.
|
|-
| Cardboard, carton
| thicker
| Cuts well but may catch fire.
| Watch for fire.
|-
| Cork
| 1/4"
| Cuts nicely, but the quality of the cut depends on the thickness and quality of the cork. Engineered cork has a lot of glue in it, and may not cut as well.
| Avoid thicker cork.
|-
| Acrylic/Lucite/Plexiglas/PMMA
| 1/2"
| Cuts extremely well leaving a beautifully polished edge.
|
|-
| Delrin (POM)
| thin
| Delrin comes in a number of shore strengths (hardness) and the harder Delrin tends to work better. Great for gears!
|
|-
| Kapton tape (Polyimide)
| 1/16"
| Works well, in thin sheets and strips like tape.
|
|-
| Mylar
| 1/16"
| Works well if it's thin. Thick mylar has a tendency to warp, bubble, and curl
| Gold coated mylar will not work.
|-
| Solid Styrene
| 1/16"
| Smokes a lot when cut, but can be cut.
| Keep it thin.
|-
| Depron foam
| 1/4"
| Used a lot for hobby, RC aircraft, architectural models, and toys. 1/4" cuts nicely, with a smooth edge.
| Must be constantly monitored.
|-
| Gator foam
|
| Foam core gets burned and eaten away compared to the top and bottom hard paper shell.
| Not a fantastic thing to cut, but it can be cut if watched.
|-
| Cloth/felt/hemp/cotton
|
| They all cut well. Our "advanced" laser training class teaches lace-making.
| Not plastic coated or impregnated cloth!
|-
| Leather/Suede
| 1/8"
| Leather is very hard to cut, but can be if it's thinner than a belt (call it 1/8"). Our "Advanced" laser training class covers this.
| Real leather only! '''Not''' 'pleather' or other imitations!
|-
| Magnetic Sheet
|
| Cuts beautifully
|
|-
| NON-CHLORINE-containing rubber
|
| Fine for cutting.
| Beware chlorine-containing rubber!
|-
| Teflon (PTFE)
| thin
| Cuts OK in thin sheets
|
|-
| Carbon fiber mats/weave that has '''not''' had epoxy applied
|
| Can be cut, very slowly.
| You must not cut carbon fiber that has been coated!!
|-
| Coroplast ('corrugated plastic')
| 1/4"
| Difficult because of the vertical strips. Three passes at 80% power, 7% speed, and it will be slightly connected still at the bottom from the vertical strips.
|
|}

=== Etching ===

All the above "cuttable" materials can be etched, in some cases very deeply.

In addition, you can etch:

! WARNINGS!
|-
| Glass
| Green seems to work best...looks sandblasted.
| Only FLAT GLASS can be engraved in our cutter. No round or cylindrical items.
|-
| Ceramic tile

|-
| Stone, Marble, Granite, Soapstone, Onyx.
| Gets a white "textured" look when etched.
| 100% power, 50% speed or less works well for etching.

Laser Cutter

Bmanifold: /* Cutting/Engraving Material Suppliers */

{{side box|text = this is a test}}
[[File:lasercutter.jpeg|frame|right|x350px|Our homemade laser cutter.|alt=Our homemade laser cutter.]]

We have a [http://www.buildlog.net/blog/2011/02/buildlog-net-2-x-laser/ Buildog.net 2.x Laser] on site at Knox Makers. It is capable of cutting, engraving, and marking a number of different materials quickly and accurately when driven from CAD software such as Inkscape.

== Buildlog 2.x Laser ==

The Buildlog.net 2.x Laser is an open source laser cutter/engraver. The usable work envelope is just under 12” x 20” x 4” or 300mm x 500mm x 100mm. The machine uses a 40W CO2 infrared laser to engrave/cut. Detailed information on it's operation is provided below, but the general theory of operation is as follows. Inside the laser cutter there is a very powerful CO2 infrared laser that is bounced off of a few mirrors and is finally directed towards the material being cut or etched by a moving mirror and lens that focuses the coherent beam. These mirrors and lenses are gold coated to provide the best possible transmission of infrared energy.

There are two main variables that the laser uses to cut and etch: speed and power. When cutting, the laser power is increased and the speed is decreased so that the cutting beam spends a longer time hitting the material in order to cut though. While etching the speed is increased and/or the power reduced, this way the laser only removes a little material from the surface, leaving just the etching.

== Usage ==
You must take the [[Laser Operation Class]] in order to have permission to use the laser cutter. The laser cutter is a very powerful, but also easy to break machine that requires some training to be able to use effectively and safely. Once you have taken the class, you will be added to the [https://docs.google.com/spreadsheets/d/1dGRW5Dh4zC9mhChBooV--RfmehFxs9Sdpk9r0sWa6_8/edit?usp=sharing Knox Makers Laser Cutter Checkout List].

At this time, we do not plan to schedule the usage of the laser cutter. If usage is heavier than anticipated, we reserve the right to institute a scheduling system to be fair to other users.

When you arrive at the space, remember to sign in and sign out on the log sheet. Please note any damage or issues with the laser when you sign in.

== Materials ==
There are a wide range of materials that the Laser Cutter can cut, etch or mark - but some simply don't work (eg metals) and some are extremely hazardous to either humans or the machine itself. It is therefore imperative that you check the list of [[Laser Cutter Materials]] before attempting to cut materials that you have not worked with before.

== Laser Cutter Settings ==
There has been some preliminary testing with common materials to generate a set of recommended values for speed and laser power: [[Laser Cutter Settings]]. These values have been included as defaults into our laser cutter Inkscape plug-in. The values should be acceptable for the listed materials, and can serve as a starting point for testing for other materials. The laser settings are internally limited to prevent damaging the laser, so feel free to experiment.

Beyond changing speed and laser power, do not attempt to change the configuration of the laser cutter. These settings are calibrated regularly by our Laser Cutting [[SME]] and are not intended for users to change. Doing this messes up other people's work and it's NOT COOL. As with everything in the space, when you're done, leave things better than they were when you started. Changing settings could mean the laser is not right when the next person comes to use the machine.

== Manuals ==
Editor's Note: Do we have anything that goes in here?

== Theory: How it Works ==
Inside the laser cutter there is a very powerful CO2 infrared laser that is bounced off of a few mirrors onto a moving head and is finally directed towards the material being cut or etched by a moving mirror and lens that focuses the coherent beam. These mirrors and lenses are gold coated to provide the best possible transmission of infrared energy.

The infrared (IR) light that the laser cutter produces would blind you instantly if you were to look directly at it - and it's so bright that even you were only looking at the light reflected off the material that's being cut, it could still blind you. The IR light is also totally invisible. Fortunately, IR light doesn't pass easily through the window of the cutter that is made of a Polycarbonate plastic (which strongly absorbs light in those wavelengths). For this reason, if the lid (and the front panel) of the laser are not properly shut, then the IR laser will turn off automatically. The intense white light that you sometimes see when the cutter is operating is actually visible light that's being emitted by the material that the laser is burning off (it's literally 'white hot'!).

For carbon-based (organic) materials (like wood, paper, cloth and leather), you see the material being burned away and there may be black residue left behind. For plastics like Acrylic, the material is chemically decomposed by the laser and you don't see that white hot trail as it cuts. However, when the laser hits the metal grid beneath the material, there will still be bright flashes of light from that.

== Making drawings for the Laser Cutter ==
'''''See Also: [[Using Inkscape with the Laser Cutter]]'''''

The recommended software path is to design your drawing in Inkscape, use the KMLaser bundle to export your drawing into gcode, then import the gcode to LinuxCNC which drives our laser cutter.

However, these are only conventions. The only requirements is that your design ends in gcode that is understood by our configuration of LinuxCNC. [[Laser Cutter Settings]] is a good reference with explanations of the values you will need to set in your gcode.

The IR light is also totally invisible. Fortunately, IR light doesn't pass easily through the window of the cutter that is made of a Polycarbonate plastic (which strongly absorbs light in those wavelengths). For this reason, if the lid (and the front panel) of the laser are not properly shut, then the IR laser will turn off automatically. The intense white light that you sometimes see when the cutter is operating is actually visible light that's being emitted by the material that the laser is burning off (it's literally 'white hot'!).

For carbon-based (organic) materials (like wood, paper, cloth and leather), you see the material being burned away and there may be black residue left behind. For plastics like Acrylic, the material is chemically decomposed by the laser and you don't see that white hot trail as it cuts. However, when the laser hits the metal grid beneath the material, there will still be bright flashes of light from that.

'''''See Also: [[Using Inkscape with the Laser Cutter]]'''''

The recommended software path is to design your drawing in Inkscape, use the KMLaser bundle to export your drawing into gcode, then import the gcode to LinuxCNC which drives our laser cutter.

However, these are only conventions. The only requirements is that your design ends in gcode that is understood by our configuration of LinuxCNC. [[Laser Cutter Settings]] is a good reference with explanations of the values you will need to set in your gcode.

Laser Cutter

[[File:lasercutter.jpeg|frame|right|x350px|Our homemade laser cutter.|alt=Our homemade laser cutter.]]

We have a '''Buildlog 2.x 40W Laser''' on site at Hackerspace. It is capable of cutting, engraving, and marking a number of different materials quickly and accurately when driven from CAD software such as Inkscape.

== Buildlog 2.x Laser ==

Inside the laser cutter there is a very powerful CO2 infrared laser that is bounced off of a few mirrors and is finally directed towards the material being cut or etched by a moving mirror and lens that focuses the coherent beam. These mirrors and lenses are gold coated to provide the best possible transmission of infrared energy.

There are two main variables that the laser uses to cut and etch: speed and power. When cutting, the laser power is increased and the speed is decreased so that the cutting beam spends a longer time hitting the material in order to cut though. While etching the speed is increased and/or the power reduced, this way the laser only removes a little material from the surface, leaving just the etching.

== Usage ==
You must take the [[Laser Operation Class]] in order to have permission to use the laser cutter. The laser cutter is a very powerful, but also easy to break machine that requires some training to be able to use effectively and safely. Once you have taken the class, you will be added to the [https://docs.google.com/spreadsheets/d/1dGRW5Dh4zC9mhChBooV--RfmehFxs9Sdpk9r0sWa6_8/edit?usp=sharing Knox Makers Laser Cutter Checkout List].

At this time, we do not plan to schedule the usage of the laser cutter. If usage is heavier than anticipated, we reserve the right to institute a scheduling system to be fair to other users.

When you arrive at the space, remember to sign in and sign out on the log sheet. Please note any damage or issues with the laser when you sign in.

== Materials ==
There are a wide range of materials that the Laser Cutter can cut, etch or mark - but some simply don't work (eg metals) and some are extremely hazardous to either humans or the machine itself. It is therefore imperative that you check the list of [[Laser Cutter Materials]] before attempting to cut materials that you have not worked with before.

== Laser Cutter Settings ==
There has been some preliminary testing with common materials to generate a set of recommended values for speed and laser power: [[Laser Cutter Settings]]. These values have been included as defaults into our laser cutter Inkscape plug-in. The values should be acceptable for the listed materials, and can serve as a starting point for testing for other materials. The laser settings are internally limited to prevent damaging the laser, so feel free to experiment.

Beyond changing speed and laser power, do not attempt to change the configuration of the laser cutter. These settings are calibrated regularly by our Laser Cutting [[SME]] and are not intended for users to change. Doing this messes up other people's work and it's NOT COOL. As with everything in the space, when you're done, leave things better than they were when you started. Changing settings could mean the laser is not right when the next person comes to use the machine.

== Manuals ==
Editor's Note: Do we have anything that goes in here?
