Re: EMC Stepper Calibration???

Steve,
Here are two things to check. If you already set these, please
disregard. Both are in the .ini file
1.Linear Units=1.0 (for metric and 0.03937007874016 for imperial)
2.input scale (AND) output scale should equal motor steps per rev
divided by lead screw pitch. Be sure to included all pulley ratio's
and/or microstep settings in the motor steps per rev section.

I hope this helps.
