Slic3 Laser Cutter (wip)

This is the laser cutter I've spent alot of time on a few months ago, It uses a gantry crane design to cheaply and effectively make a laser cutter that is very accurate. It requires 2x nema 17 motors, 1/4-20 threaded rod, 1/8in smooth rod, 1/8 bearings, 1/4-20 threaded nut, laser assembly, a 3d printer (duh), and some ingenuity. At 13y/o I can design virtually anything in solidworks, and 3d print it with my da vinci, but i'm not great at grbl programming. That's where I could use some help setti
