	We have a super secret, super effective method to get ABS to stick to glass: Garnier Fructis Bamboo Extract ~~Shampoo~~, extra hold. This stuff is STICKY. I recommend to reapply when there are VISIBLY MISSING places on the glass... the hairspray is somewhat bumpy or translucent... whereas clear glass looks like... clear glass. If there are big bare spots in the middle of the plate (or otherwise), CAREFULLY remove the glass, clean it with WARM or HOT water (cold won't remove the gunk), then reapply 3 light coats of spray, letting each dry in between.

There are 3 things you need to acquire in order to use the printer: slicing software which generates the GCODE (slic3r), printer controller software that measures temperatures and sends code to the RAMPS board (printrun / pronterface), and custom configuration software we have created specifically for this project (on github).
	===slic3r===		===slic3r===
	You can acquire slic3r here: http://slic3r.org/ Slic3r takes STL files as input. Essentially what it does is take the STL solid and split it into a series of Z axis sections. Each section becomes a GCODE profile, which is used by the printer to make the objects.		You can acquire slic3r here: http://slic3r.org/ Slic3r takes STL files as input.

	===Configuration Files===		===Configuration Files===
	Configuration files are very specific to each printer, and each type of filament. If you change printers, and sometimes if you change filaments, you will need to tweak the slic3r configuration files. Most likely, you won't need the firmware / Marlin config for normal operations. To get the configs, either ask someone at the space, or get them from here ~~(requires GIT)~~ https://github.com/KnoxMakers/3d_print.git		Configuration files are very specific to each printer, and each type of filament.

Levelling the bed

	===Levelling the bed===		===Levelling the bed===
			Levelling the bed is super important and sort of a pain. It's pretty darned level now. What makes it more challenging is it's 3 point levelling instead of 4. I recommend you leave this alone, but you can tell by moving to X, Y, and Z home, then moving the head around with pronterface to each corner (+180 mm X and Y) to verify the level. Ideally you want to test with a shim, something like 2 sheets of paper, or a leaf gauge.

First Layer Adhesion

	===First Layer Adhesion===		===First Layer Adhesion===
			First layer can make or break your prints. You want something that looks a little squished, but not flat. Completely round is bad, and completely flat is bad. You want something in between. If your skirt isn't printing right, STOP the print, rehome Z, and then restart.

Home the Z axis

	===Home the Z axis===		===Home the Z axis===
			Here we get into some of the tedium / art of printing. Mechanical endstops get close but don't have the required precision (like .1 mm). What you will want to do is go ahead and hit Z home button. Then, click to raise the Z axis by .1 mm until you JUST see the head lift off the glass. Then, click down .1 mm until you are JUST ABOVE or JUST TOUCHING the glass. You need a clean extruder and a level bed for this to work well, but you'll find with some practice what is 'acceptable'. After you find your physical Z, you want to tell pronterface that the head is now actually at Z zero. The gcode command for this is
			G92 Z0

			In pronterface in the top left corner, near the big concentric circles, go ahead and hit the X home and Y home buttons. The mechanical endstops work for this reasonably well.

			You can drop multiple objects in the Plater to print many at the same time, or you can rotate, scale, or duplicate items in the Plater as well.
			Important settings:
			*Print Settings
			**Layers and Perimeters -> Layer height default should be .36 mm. .3 to .4 works, maybe smaller down to .2 if everything is properly calibrated.
			**Infill -> Fill density should be between .1 and .5, Fill pattern rectilinear or honeycomb recommended
			*Filament Settings
			**If you change filament, measure carefully in 3 places and average the results. Put this in Filament -> Diameter
			Once your settings are good and your part added to the Plater, click Export GCode to generate your gcode, which is then loaded into pronterface.
