6.3 Setting up Pulleys
For Mach3 to know how to scale the analog voltage output, you must enter in your maximum RPM for the spindle
motor. 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 40.
