The moment We've all been waiting for... Or at least I have.
Not sure why Inkscape decided to draw every line twice, something about edge-detection? And where'd it get the curves in the wrenches? Dunno.
USE GOGGLES, and Open The Window. That be burning-plastic smoke you see in the video.
Grbl has been hardware-abstracted and ported to PIC32, per the last log. Also added direct-support for PWM-microstepping output within grbl, to be fed directly into H-bridges, rather than the normal "step/direction" output usually fed into an EasyStepper. (The PWM output is a sine-wave fed into the two windings, 90degrees out-of-phase).
Other tools: Universal G-Code Sender (java-based), Inkscape with the Gcodetools extension, (Inkscape CNC (G-Code) tutorial - YouTube), Grbl, 2 DVD drives (the burning-laser is, I think, from a 20x drive, running at 250mA, just remove the focussing lens, and the focal-point is about a foot away),
