General Mach Discussion / Motor Setup Problem
« on: August 08, 2008, 06:35:34 PM »
Hello all. I am new to the boards and this will be my first post. 

I am in the process of building my first CNC Router and am having some problems.  My electronics are from Probotix and I am running Mach3.

My problem:  I have wired up everything according to the manufacturer diagrams, set all the jumpers, programmed the ports and pins into Mach3 and my z-axis motor doesn't work.  I get x and y reliably with no problems.  Early on I would have x and y or x and z, but not all three.  Now I just get x and y.  I checked the Inhibit and enable features in Mach3 and they are not inhibiting z-axis movement.  when I run a program the DRO for the z axis changes, but no motor movement. I also measured the voltage at the driver board for the z axis and get no voltages at all.  The x and y axis driver boards show voltages.
So I am down to the following conclusions:
1) Bad driver board (will test this tonight)
2) Bad breakout board (will also test this tonight)
3) Setting I missed in Mach3 (Need help with this one)

Anyone have any other possible sources of errors?

I thank you in advance for your help!
