keebler303-
I checked all the connectors, and they look fine. I also made sure that the connector was fully seated in the encoders.
Tero-
I added the 100 ohm resistors to the y axis, and nothing changed.
I also removed the encoder cable to the y axis, and there was not a mark on it. I also used a meter and checked all the wires in the cable, and everything checked out.
I moved pieces and parts around, and I could not find anything bad.
Now one of the x axis encoders has stopped working. So now I have three not working

I am going to call US Digital tomorrow and see what they say.
Is it possible that the encoders and the VSD-E's are not compatible?
How can I test the encoders and not have them connected to the VSD-e???
Thanks for the help
