z axes just humming like not enough current.
this was working perfect for weeks.
i just dont understand. -
have you tried to connect the stepper not working to another axis?

@mikeb said in Axis stop working....:

i just dont understand.The most likely reason is a bad crimp connection in that motor cable. A failed driver chip is another possibility.
-
i will ohm out the wires and try to use different axis driver. thank you for response! thank you
-
ok i hooked up two spare motors and what happened was both are buzzing but one turned as normal and other was back and forth couple of steps. think check crimps one one not turning as normal.

As a side note to this issue, and any other issue that might be related!
I had a project in which we used huge amounts of connectors pretty much identical to the ones used on the Duet boards. It was not the first project, as I had very good previous experience with the same type of connectors. Some if the guys crimping the pins on the wires misplaced them in the crimping tool and they have squeezed the contact area way to much. We had to get the pins out of the plastic bodies and re-spring them for quite a few of the cables. The problems were random, so finding the actual cause was anything but simple!
Also, we saw that even "compatible", these connectors are not 100% identical between manufacturers, with slight variations in the latching dents and the actual pin shape. If all sourced from the same manufacturer, everything is OK. But this is a relatively low cost connector, though a pretty well designed one, so there are a lot of manufacturers and only few suppliers guarantee the manufacturer (go for big suppliers like Farnell, Mouser, DigiKey, TME in order to have guaranteed supplier, but avoid generic ones - like Multicomp for Farnell). I think on Duet the connectors are from Wurth!

im still using supplied ones from e3d.

update...i updated my firmware and that fixed my motor issue on z axes.
but now i have no controle of my eo heater and the bed thermister is what both eo and bed are displaying. crazy -
@mikeb ALL FIXED NOW. i fixed numbering of heaters and thermisters. the configurator had it all messed up. never did that before. was same config as before. guess update changed something. THANKS FOR ALL HELP EVERYONE.
-
ok now z motors stuttering again. started in middle of a print! i just cant win
-
@mikeb i figured out one of the motors has let the carriage get in a bind(one side 3/4 turn off). ?
-
think i will get e3d 2.0a stepper x1 and go overhead belt drive to remedy this. think im having motor issues. and i wont have to check that they are equal all time also(x2 z motors now). if anyone has a clue whats going on please tell me.
