Setup Gears in Mach4

Setup gears

If you do not know the gear ratio on the spindle, setup the spindle as follows:

  1. Turn on spindle at the max spindle speed of the current pulley loaded
  2. Read RPM using spindle encoder or TACK
  3. Set pulley to above RPM

The Max Spindle Motor RPM from Mach4 is not used in this instance.

Also, note that for Gear 1, the 0-10V from the Apollo III will be scaled by 0-814 RPM. So with pulley 1 active, 814 RPM will output 10V on the Apollo III.
