I am a noob with a Zenbot Mini , aftermarket controller, Artcam and Mach 3.
As the program runs the second pass moves approx .250" in the +y direction the the third pass moves another .250" and so on.
I have only cut pink foam so far so I have not trashed any bits , but I need to fix this before I try to cut wood.
Any ideas what may be telling it to shift each pass?
Thanks

If you attach your xml and problem code I will have a look.
