Re: Mach 4 running tool off the table at the start?

If you want to work in metric double check the configuration is set to metric.
If that checks out revisit the motor tuning and make sure the pulses/unit (or whatever Mach4 calls it) is set correctly. Mach4 will have a manual explaining the math.
The steppers are most likely 200 steps/rev, don't forget to include any micro-stepping in the calculation.
edit/ A quick google shows Mach4 terminology is 'Counts per Unit'
Anyone who says "It only goes together one way" has no imagination.
