I'm in the process of setting up a new cnc router and evaluating cut2d/cut3d and I'm getting unexpected behavior when using the g-code files it generates. The machine is set up and moving all axis as expected, but after importing a g-code file from the Vectric software (both Mach3 ARC and ATC post processors), the machines movements are all off as if the scale of the machine has been changed. The Mach3 DRO will tell me I've moved .1", but it has physically moved several inches.

After assuming that I was mixing metric and US, I went back, restarted everything, and did the whole process again. All in inches, and tried both Mach3 post processors again. Same result.

Can someone please point me at what I am doing wrong? Has anyone seen this before.

Thanks,
Mike
