Title: Mach 3 -Z axis problem
Post by: tjbourne on June 24, 2022, 11:20:11 AM

My router has been working fine with Mach3 for almost a year.  Whatever code is sent to the controller now, the Z-axis rises from "0" and continues until it hits the limit switch. The G-code appears to read ok.

Does anyone have a clue what might be causing this? I haven't changed any settings that I'm aware of. I hope this is something really simple that I have missed, as I'm behind with a project that should be finished today. Thanks for any help you can give

 Could it be your safe z settings?
