Does anybody Familiar with Pathpilot 2.0 Know where I would go about adjusting the Stepper / steps per rev?
The x axis on my mill overtravels by approximately 0.0002" - 0.0003" per inch. The problem is not backlash or gib related. Backlash checks at (0.0004' - 0.0006"), and small holes will interpolate round within 0.001' TIR or less. The error stacks in a linear fashion. I verified this via both CMM'ing a long plate with reamed holes in it and cutting slots, checking the distance between them.
This is not a new problem on this machine, Ive always noticed pockets seamed to cut tighter in the Y axis, but I have a few long plates that require the holes to be within +/- 0.001" positionaly, so i need to sort it out.

For anyone interested I found it. It is in the Tormach_mill_base.ini file. I was able to modify the Stepcount (steps per inch) based on the error I was seeing. The machine now appears to cuts correctly.

you'll want to edit the tormach_mill_specific.ini for you mill file
thats where you override the base ini file at in PP. the base as I recall will get re-written so you can loose your changes, the specific does not.
just add the AXIS stanza if not there and the parms you want to override
