Let me share my latest TAZ6 adventure but first here are my printer stats taken from the “About” screen on my printer.
I have a total of 50d 21h 13m 38s of print time (call it 51 days of printing or 1,224 hours.
Total print count 552 and I have completed 507 for a success-ish rate 93%. A completed print does not mean a successful print.
The longest job (print) was 21h 3m
Extruded 1643.6 m of filament.
Early on, I had challenges with cheap/crappy filament, not knowing what I doing (learning the printer do’s and don’ts) and then a thermistor on the hot end not reading correctly that came with the TAZ6. Replaced the thermistor and life’s been mostly good in TAZ6 land.
Done boring you with non-essential information, let’s get to the challenge.
1/3 of the way through a 13 hour print the z-axis step motor stopped doing their job. I did discover the problem about half way through and stopped the print. I was having the same symptoms as “CallDrop” in this thread (see the video they posted):
TAZ 6 - problem with Z axis --- HELP
Verified frame was square – it was.
Verified left and right worm thread height to bearings were equal – there where.
Try to isolate whether the challenge was one or both z axis stepper motors, cables, connectors, or the Rambo 1.3L board with the following steps:
a. Removed connectors at both z step motors. Then removed connector on the x-axis step motor.
b. Clipped associated tie wrap and connected left side z-axis motor connector to x-axis step motor. Operated the TAZ movement in the z axis and got the crazy rattling on the x-axis step motor.
Thus, z-axis step motors are probably good.
c. Opened up electronics, clipped tie wraps as required and connected the left side z-axis connector (remember the other side is connected to x-axis motor) to the x-axis socket on the board. X-axis worked well.
Conclusion, problem is probably not the cable, connector or z-axis motors but the Rambo 1.3L board.
Board on order (no warranty).
