Hi there, my name is Nick I have only just started in cnc and in the process of building my first xyz table, I have connected the machine and trial running Mach3, but am having a problem withe Z axis, in the program it shows the z axis as going up but on my machine it is actually going down and vise versa, is there a setting in Mach 3 to change the rotation of the stepper from VW to CCW or do I have to change the wiring on the motor or the drivers? Like I said I have very little knowledge of the whole cnc concept, only what I have learned from the internet and looking at a lot of utube videos

Hi Nick,

Welcome to the forum.

Within Mach - Config / Ports & Pins / Motor Outputs - change the Dir Low Active state for your Z axis.

That should do it.

Thanks for the info Tweakie, sorry I took so long to get back to you, I was out of town for the week, I tried it and it worked!!!!Thanks again

Nick
