help with g201 needed

Hi, hope someone here can help. I've got a Taig micromill converted to CNC
with 3 G201A's using CNCpro. It was working well before Christmas. I get
back from holidays and tried to do some work on it and the Z axis only goes
up, it doesn't matter which direction I try to move it. I swapped the
cable with the X axis and then the X axis would only go one direction no
matter which direction I wanted it to move while the Z axis now works
correctly. I did no changes, or even had anything open since the last time
I successfully used it. Any suggestions?

Thanks,
Al
