Hello folks,
I have just finished building a large gantry style CNC and I am in the middle of calibration. The problem I am having is that because of how I built my table I needed to use two motors for the 8ft Y axis. So in Mach 3 It was easy enough to set up the other motor (b) as a slave to Y and I can sync their movements just fine, but now that I am trying to auto calibrate the step count the auto calibrate only moves one axis at a time, which is no good because it will skew the table. Do any of you know of a way to get the auto calibrate to do this? Or does anyone have enough knowledge to tell me where to tweak the API perhaps? I don't think it would be very difficult to add a few lines of code that would allow a user to select a drive and hold down shift to select a slave drive to auto calibrate.

Thanks in advance for any help.

There's no way to use the calibrate on a slaved axis. Just do the math to calculate the correct steps.
