Anyone familiar with Peddinghaus beam drill line? We need help!

We've been having problems with our BDL1250/9 Peddinghaus beam drill line running on Windows 95.

X axis will not reference. Ie: Programmed beam starts of as normal and then shoots back instead of forward.

We've been talking to the Peddinghaus techs for about 2 months now, even had one tech come to our shop to fix this issue with no luck. Uninstalled the BDL software on Windows 95 and re-enstalled with new version from Peddinghaus. We've changed the X and Y-axis modules, checked the voltage,checked electrical, laser.

Please help
