All, Thanks for the input: Indeed it was a mechanical problem. I have a Delta Printer with parallel Poles (D=16) and the carriages do have teflon coated bearing bushes from GLACIER. One of the bushes came lose what was causing this nasty problem. I have changed the design to ball bearing bushes from INA. All is okay now.
