Help needed...

At some point in the middle of my g-code, x goes negative (x being the cutting axis) and this is bad since my cutter tries to cross the piece to the other side and then continue cutting from there... except there's a workpiece so it cannot...

HELP pleaaaseeee

Mach is doing exactly what your gcode file tells it to do.
Check your setup.....change the code....

Sorry to bump an old thread, but for others reading this I feel I should clarify what happened here.

In actual fact Mach3 wasn't doing what the GCode told it to do. There was a glitch somewhere in the OS. The toolpath window would show a toolpath that did not follow the provided GCode. X would suddenly flip negative for no reason whatsoever- not a single negative X value in the file...

The solution for him was to format the hard drive, reload windows and the Mach3 software. Nothing short of this seemed to help.

Thanks,

Chris

Glad you got it working and sharing what you found. It's shurely an odd one.
