So we have been using our Robo R2 for a year or 2 now but now the extruder stepper motor seems to be malfunctioning. We wanted to confirm if there was a fix or whether we need a new stepper motor. So the problem started after the printer was moved location then did 2 16 hour prints. After these it then got half way to two thirds of the way through various other prints. We removed the surrounds cleaned any residue assuming it just needed cleaning. Now as you can see the motor seems to be skipping/not rotating. When light pressure applied it will start to rotate then get stuck again (not always in the same place). So long story short i have seen posts about stepper drivers and cleaning out contacts we have looked at but does not seem to fix the issue. So is there a fix or do we need a new stepper motor? Please let me know if you need anymore information!
