Calibrating PWM Spindle RPMs by hand
« on: March 21, 2011, 10:29:55 AM »
Is there a way to calibrate the RPMs on a PWM Spindle by hand?

Meaning instead of having the electronic feedback we can just measure the actual RPMs for a series of "S" instructions and then somehow use that to derive the calibration curve for Mach3 to use.

Thanks!

There is a function in the function cfg's menu.

Called calibrate spindle but never use it but maybe this is what you're looking for.

Thanks, but unfortunately that video does use a "C3 index card" for electronic feedback.

I'm looking for a manual method to do that sort of calibration.
