Hi CharlyCR. I believe Ron has been helping you with this through email / our ticket system, correct? We’re happy to share this information publicly for others to find results. However, if at all possible, it would be a little easier (and quicker) for us to help you from one. Is it possible to allow Ron to help from email?
I just found a similar issue with my klic n print printer……X axis did not travel smoothly and sounded like the motor was grinding sometimes. If I wiggled the X axis cable in jog mode while manually moving the X axis……the motor would act normally intermittently. Removed X axis cable and found a broken wire. Repaired wire and printer works normally now.
