I’ve got an issue with my Taz 5 suddenly… It’ll print about 2mm tall worth of a print then all the sudden the herringbone gear and hobbed bolt stop spinning. I guess for whatever reason the stepper motor stops rotating.
I checked my small herringbone gear and made sure the little screw in the side was tightened… Restarted a print and same issue. I did notice that the small gear was sitting a bit “cock-eyed” in relation to the larger gear… but the teeth were locked together just fine and up until the 2mm point it spins the large gear just fine…
Piercet suggested that if it wasn’t the small gear then it could be a motor cable short, a failing motor coil or a failing control chip on the rambo board. Thus I am going to change the motor cable now since it came with 2 cable and see if it works from there… I am hoping it’s not the latter – not sure how that gets repaired.
Any other suggestions / sanity checks? I added a few pics…
