Title: Z-axis +/- reversed
Post by: msffemt4147@gmail.com on November 17, 2021, 07:18:39 PM

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.

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.
