How does Mach send the PWM back to SuperPID?
« on: August 02, 2021, 07:47:48 PM »
Hi,

Is there anyone that could help me understand how Mach talks to the PID to modulate the RPM? Does Mach need to see an RPM to calculate the Pulse back to the PID? I can turn the router on and off through Mach but it will not control the RPM  its just wide open and when you turn on the spindle I see no RPM in Mach. I see RPM on the PID but I am wondering if this is a calculation or if I am missing a wire back to Mach to see the RPM? There is no videos that helps to set up Mach3 for spindles or trouble shooting. I would appreciate any input on this.
