Thank you Duncan, we've been having trouble with the z axis drive system the
machine keeps outputting "z axis position errors" we belive the aligment to the bar
relative to the drive roller is not being kept by the machine . Have you guys had
trouble with this type of drive systems in the past ? I know your new machines have a belt driven system. If it was up to me I would already had a service rep. from your
company come in and fix the problem. can you give us any suggestions on how to aling the bar and rollers to themselves? We have been following the instructions in the manual but it seems something is missing or we are not doing.

well thank you for help maybe we will see you guys in the near future.
