General Mach Discussion / Re: Mach3 Turn VFD Setup Help
« on: August 27, 2013, 06:07:47 PM »
Just to complete the thread....
i figured it out.
1. I changed the belt pulley to the slower one on the DC motor.(Biggest change)
2. I tuned the PID in Mach for the best startup and stability (took the most time)
3. I reduced debounce to 0
Running the wizard for thread cutting, (and cutting air), the stability of the motor appears to be great (withon 2RPM of target at all times)
I've tested down to 250RPM, and appear to be stable, and within the good portion of the torque curve of the Sherline motor.
I had to add a 'G4 P10' after the 'S250' command to give adequate time for startup and settling at desired RPM.
I will report more when I understand enough about threading to actually cut something that is testable against a standard.
VR,
Bruce
