Clearing Mach3 Spindle Calibration Parameters

Description of the problem:
The 0-10VDC spindle speed signal is not linear. It doesn't change consistently with commanded RPM.
At some point the spindle was calibrated in Mach3. MachMotion motion controllers do not  require calibration.

To clear spindle tuning parameters in Mach3:

  1. Close Mach3
  2. Open C:\Mach3\macros\[your profile]
  3. Delete the highlighted files
  4. When Mach3 is restarted the calibration will be gone
