Please indicate if the DTERR is posted against a single axis or several?
This can help narrow down cable vs. encoder issues.Are you experiencing CRCERR errors as well?
Is yours a paint controller?
Exactly which mechanical unit?
Mine is a paint controller and it is on all axis.... They disconnected and then reconnected all the cables in the base. They also removed the cables in the arm when they did not have to. I'm trying to find out what is common to all axis?
