Y-axis motor turns one direction

I have used emc2 for 5 years with no issues. I replaced the z-axis controller and ran the stepconfig file. I attempted to home the machine and my y-axis motor only moves in the negative direction. I compared the new stepconfig to the original one and the values are the same.

I downloaded the 2.5 iso to see if the problem would go away but it didn't. What am I missing?

Background info:
Ubuntu 10.4
Emc2 2.4.3
Drivers: oms mh10

John,

I rechecked all connections and the problem appears to be the controller. I switched connections with a working axis and the motor work perfectly. I then switched the step/direction connection and it continued to work.

I ordered another controller (Centent 142) and installed it Saturday. Much to my surprise, I have a new issue. The motor makes a loud hammering sound and barely turns. In fact it will turn both directions. I installed the controller on the z-axis and it did the same thing. I am hoping for a senior moment and not another bad axis.

What am I missing?

Thanks for your help!

Adrian

Andy,
I will give that a try. My understanding is centent drives are nearly identical to Oregon micro system drives. This driver placement for the centent. I will give it a try and report back.
