This video, https://youtu.be/tTyAu8GTBFk, is of a manual 10mm extrude attempt followed by a 10mm retraction via Repetier host. As you can see (i hope, quality may be loww), the gear shakes back and forth, it does spin smoothly in a single direction.
I would appreciate any insight as to what I should investigate, I’m at a loss here.
Apologies, I realize now that this should have been in the mp3d printing troubleshooting board. If you would rather I repost this question there, please let me know and I will.
Still have 3 jumpers under it? using the right steps in the firmware? can you loosen the tension on the spring or is it all the way loose? Have you tried .7V? double check your wires, one loose one will do that? Does it move if you pinch the tension gear out of the way? Is it up to temp, at least 170C?
Can you plug in a another stepper to that driver? Then try plugging one into the end of the existing wires. At this point there are too many things it could be we haven’t really narrowed it down at all. I think it is a wiring issue but maybe not.
After additional troubleshooting, I have discovered that this is in fact a wire problem. I replaced my current extruder stepper motor cord with a new one, and the motor began running as expected. Thanks again for the assistance.
