I recorded some of my work converting the V1 to the V2, this time I focused on meshing my HObbyCNC pro unipolar driver board to a GRBL interface. Then I tested out some options for sending Gcode. Chillipeppr seems to be the best. I still have a 1mm wobble of the pen or bit when the Z axis moves.

That’s a pretty cool rundown of all the software you tried. That’s a pretty crazy setup with that parallel port, but I get that you just wanted to use the stuff you had lying around. Nice work!
