Need Help! Bridgeport Series I X-axis won't move

Dear All,

Hopefully someone can help me out here.
I've got a Series I machine which used to run very well untill it stopped moving the X-axis. When I try to move the table you'll see it trying to start moving but then the motors starts to windup imidiately. No I can't find what causes this failure. This is what I've already tried.

- Checked transistor plates.
- Checked all diodes on the side of cabinet
- Checked SMD-board by trying it on another axis.
- Checked the fuses related to this axis
- Checked motor connections
- Checked mechanical connection to the table.

This is where my knowledge stops so if there's somebody with suggestions about what I should try it would be great!

Thanks,
Bart
