Title: Z axis Home?
Post by: highpockets on April 04, 2015, 04:08:23 PM

I have my new CNC router up and running, it's a PDJ 2626 running Mach3.
I have ref home on X and Y working just as they should, but Z is another story. If I turn on Z Home in Port & Pins Inputs when I click on Ref All Home the Z axis goes down instead of up. If I reverse the motor then it zeros to the top but in operation the Z axis moves in the wrong direction. I've tried every setting I can think of I'm just missing something and need help....

Here are my configuration settings.

Take the tick out of Home Negative for the Z axis, see pic. You want the Z to home in a positive direction, ie up the way.
