Hi all, I finished my mpcnc and it works fine if I use postive coordinates. Negative coordinates are simply ignored, so I am not able i.e. to lower the Z-axis
I loaded the firmware present in this site on my sanguino board (I have a good expertise with 3d printers but NOT with Cnc) and using Repetier.
The machine moves correctly but only if I use Gcode with positive values
Any help will be really appreciated
