Mach3 Setup
With your spindle wired and programmed, it is time to set up Mach3. You must enter in your maximum RPM for
the spindle motor so Mach3 knows how to scale the analog voltage output. If you have different gears, you can
set up multiple maximum speeds. Mach3 uses a different pulley for each different speed configuration. For
example, one pulley could be set to 75 to 300 RPM for a low speed (at 300 RPM the control will output 10V). A
medium speed pulley could go from 300 to 1200 RPM and high speed pulley could run from 1200 to 2400 RMP.
To change your pulleys, go to Config -> Spindle Pulleys. The Pulley Selection window will appear as shown in
Figure 7.

Use the drop down menu titled Current Pulley to select the pulley you want to update. Enter in your maximum
and minimum speeds for each pulley. Then select the pulley you want to load and press OK.
