homing problem with z on tevo delta
I have a little problem on my Tevo Delta with homing.
z does not seem to home, but after a few seconds the motor starts. Unfortunately it does not reach the top and stops about 10cm before reaching the top. (see attached)
My x and y axis are working fine, but z still causes problems.
I already tried to swap my z controller to e1 (P4), but still no success.
I have checked all wires and pinnings several times. I also crimped some again. I tried different cables. All motors are working. Amperage is fine too.
Now the strange point: If I swap the cable e.g.: from z and y, then the problem occures on my y axis and z is fine then.
I am running out of ideas what the problem could be.
(btw: I am running 1.21. I upgraded too, but without success.)
Thanks for help in advance
I suggest you start by testing the motors individually as described at https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareDeltaPrinter#Section_Testing_the_motors_individually.
When you swapped the Z and Y motor cables, did you exchange just the connectors where they plug into the Duet; or are there connectors at the stepper motor end too and you swapped the stepper motor connectors as well?
Thank you for the quick response!
I tested both ways. But the motors are working fine. I already tested them seperately.
I tested them seperately, yes.
G91 and then seperately.
Z does not react. But if i swap the connector from the z motor to the y motor (cables on board stay), then the y axis does not react.
I also tested moving my z to P4 (second extruder spot on board). Same problem.
Might this be a board problem? Or is the problem still anywhere else?
Do you have 2 jumpers in the unused Z motor connector?
Fixed. Thank you very much!
Have a nice day
