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.
This tutorial shows how to make simple shape in Inkscape.  It is the same tutorial that is used in the [[Moonraker Laser Operation Class]].  The extensions and instructions are unique to the Knox Makers system.
====Creating a shape====
# Open a new file in Inkscape.
# Go to Edit > Preferences and select Geometric Bounding Box  (first time only)
# Create a shape (square, circle, or star button)
# Choose select tool (arrow button)
# Select your shape
# Set X and Y positions to 0 ([https://www.youtube.com/watch?v=gw6DDrSgjog Video])
# Set width and height (click padlock button to keep image proportional)
# Go to Extensions > KM LASER > HERSHEY TEXT
# Type the text into the box and click Apply
# Use the X and Y positions to center your text in your shape


[http://youtu.be/dxTmhtvMNoo Make sure your objects are paths.]
====Setting the color of your shape to determine the level of engraving ====
# On the bottom, to the right of the color bar is a small arrow ( < ).  Click this and select '''KM-Laser by Color'''
#* Clicking palate color will select object's fill color.  Shift+clicking palette will set the object's stroke color.
# Set your shape to black stroke with no fill.
# Set your text to light blue stroke with no fill.
# Once you upload the file you'll be able to use different settings for each color


====Final Processing====
# Select your shape
# Go to Edit > Resize Page to Selection
# Type Ctrl-A to select everything
# Go to Path > Object to Path
# Save your file


You'll also need to either move your design to 0,0 or resize the document to match your design (which essentially moves it to 0,0).  This way you can more accurately predict where the laser will start cutting.
====Uploading your file====
# Go to moonraker2.knoxmakers.org:1337
# Choose your account (or create one if you haven't yet)
# Upload your file to your account

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.

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).

==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:

KMLaser: Path to Gcode 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:

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.

Add it to the svg_fonts folder in the inkscape extensions folder. You can then use it by selecting 'other' and typing the name of your font file. If your text does not convert to the new hershey text font, try changing what font you have the text as in Inkscape (e.g. change it to 'sans-serif' instead of a more specific font.

    • Clicking palate color will select object's fill color. Shift+clicking palette will set the object's stroke color.
  2. Set your shape to black stroke with no fill.
  3. Set your text to light blue stroke with no fill.

  2. Go to Edit > Resize Page to Selection
  3. Type Ctrl-A to select everything
  4. Go to Path > Object to Path
  5. Save your file

Uploading your file

  3. Upload your file to your account


KM Laser Extension

The KM Laser Extension has a few tools to use to make some fun projects.

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 eggbot extensions.

Video: KMLaser Hatch Fill

Hershey Text

Hershey Text produces single-stroke text that is appropriate for cnc engraving or plotters. This extension is based on part of the eggbot extensions.

To add fonts, first obtain an svg font (see this stackoverflow discussion for one way to convert true type font files to svg fonts). Add it to the svg_fonts folder in the inkscape extensions folder. You can then use it by selecting 'other' and typing the name of your font file. If your text does not convert to the new hershey text font, try changing what font you have the text as in Inkscape (e.g. change it to 'sans-serif' instead of a more specific font.

Tabbed Box Maker

This extension creates the paths necessary to cut out tabbed boxes. This extension is based of the extension you can find here.
