I followed all steps on this video (https://youtu.be/ehlgOhsmGAI), but when it try to run spindle from MACH3 it always run a high speed witch is Iangry granput on PD073, and I can decreasing it.
can any one help me with that?
I used Mach3 V3.041 with a Smooth Stepper in PWM mode and the spindle override always started at a slightly higher speed than requested. Then, I pressed “Reset” under the Spindle Speed Tab and it worked. It brought the speed back to the correct requested speed. You can try this way.
