Setup Gears in Mach4
If you do not know the gear ratio on the spindle, setup the spindle as follows:
- Turn on spindle at the max spindle speed of the current pulley loaded
- Read RPM using spindle encoder or TACK
- 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.
