SIEG iKC4 Lathe - ATC issues and refit

[PeterE]

If there is only one stepper in the ATC then you might just switch to using a UC100 and Mach3/4

Thanks John. I'll see if the issue is down to the stepper motor or stepper motor driver and if not will head down this route.

I'm hoping it is one of these though because swapping out the offending component would cause a lot less headaches than a new ATC controller.
