General Mach Discussion / Mach3 closed loop speed control
« on: October 30, 2010, 02:40:53 AM »
I'm trying to help a friend who has a CNC machine.
He wants to use the Mach3 closed loop speed control to control the speed of his router.
I know very little about Mach3 - I'm giving him advice on the electronics issues.
Could someone please point me to a description of what type of feedback signal the Mach3 PWM speed control needs.
I assume it is pulses derived from an optical shaft speed detector.
Also, how is it connected to the computer?
I have a copy of Mach3Mill_Install_Config.pdf but it lacks detail on the speed control function.
Any advice will be appreciated.
