Hello all,

I had a new problem spring up on me just recently that is leaving me scratching my head. When the machine runs the X axis goes the opposite direction from where it is supposed to go for just a brief moment, then goes the right way. I have the A axis slaved to the X on the other side of the gantry and it does not seem to be doing that, so it must be something related only to the X axis.

I had been planning on replacing my controller computer because the one that has been running it was quite old. Once that problem surfaced I figured it may be something with the parallel port going bad or something, so I configured the new computer and set it up only to find that the problem persists.

So what could it be on the driver/motor side? All connections seem to be tight. I have not moved anything around.

Andy thoughts?

THANKS!!!
