How hard is it to move the digitize led light from the diagnostic page to the program run page to make sure my probe is functioning properly. I'm running mach 3 version  R3.043.066 ?

General Mach Discussion / 4th axis

« on: January 07, 2013, 12:59:17 PM »

Hi

          I built a 4th axis for my cnc router I used two pulleys and a belt 4:1 ratio. My question is what would the difference be If I connected the stepper motor directly to the headstock shaft running the chuck.
