spindle calibration

Postby charliem » Fri Jan 06, 2017 1:18 am

I finally have UCNC working with super pid and the G540. I notice that what the Super Pid measures and what UCCNC measures is off by about 50 or so RPM. Not that that little bit matters, but is there a way to calibrate the rpm with the PWM signal?

Are you using the tach output on the Super PID to bring the rpm into UCCNC?
Or, are you saying that the commanded speed is off by 50rpm?

If the latter, what I did in Mach3 was adjust the pulley speed to get it as close as possible. But even then, it varied by up to around ±60 rpm, depending on the speed. At the time, the developer of the SuperPID said that was very good.
(I have a pre-release version of the Super PID.)

Hello Gerry,

I am using the tach output on the super pid to tell Uccnc what the rpm is. When I turn the spindle on manually what UCCNC says the rpm is is off from what the super PId says the rpm is. Also If I isssue a M3S6000 It is also off.


P.S

Gerry You close to releasing your screen set? :roll:


Thanks for the reply.
