Hi All, I just installed Mach4 Hobby. My Taig Mill worked perfectly using Mach3 but after installation of Mach4, the Z-axis is reversed. Z+ now moves the head down and Z- the opposite. Has anyone had this problem? Equipment: Taig 5019DSLS mill, UC-100 motion controller, Mach4 Hobby. Thanks in advance.

Just reverse the motor from "motors" page. Sure must be many with that "problem" but the solution is super easy.

Thanks for the quck reply.
I did try that but no joy.

With what command you see it reversed? With keyboard, from g-code Z+/Z- or when you homing?

Thanks for the reply.
The problem was in the Config>Plug-Ins>UC-100 CNC Drive>Step/Dir Settings; the check box "neg" was set. Unchecking the box fixed problem.
