At the top left of the Mach3 screen it says file, then Config, then Function Config's. click on function Config's. The first option is calibrate spindle.

That's pretty good, now have to find out if its only for pid as Dave says and look in the manual to see what I have to do
Thanks

Regarding the Function Config / Calibrate Spindle I was told that’s if you have PID.

I have ordered a RS485 adapter and when I get it I will try the Mach3 Plugin which as I understand gives good results for PWM systems.

Today I set my pulley max to 6000 RPM (ratio is always 1:1) and when I do M3S6000 the spindle went to 23479 RPM / 391Hz, the voltage from G540 to VFD was 9.53v

Changing the pulley max to 24000 RPM I get with M3S6000 spindle = 11300 RPM / 188Hz / 2.29v

It looks like the pulley setting has a big effect on the spindle but I don’t know the relation. I find it strange that when I set the pulley to max 6000 RPM the spindle will go to almost 24K RPM, 400 Hz and almost 10v. I other words increasing the pulley max. decreases the spindle RPM.

Any ideas?
