Configure 2nd Z Axis Stepper
-
@SonnyD1 Is there a chance your stepper motor is fried? You can use a multimeter and measure the resistance of both phases (should be in the single digit Ohms). Alternatively you can short one phase together, this should make turning the stepper shaft by hand more difficult. Try for both phases.
Your config looks good.
You can also try swapping the two Z motors.
Also: Never unplug a stepper motor when it's energized. Either turn the machine off first or send
M18to disable all motors.M17reenables the motors. -
@moth4017 I suppose it could be a bad stepper although its very unlikely. I have several others I could try in its place. @nikscha made a good suggestion of swapping the two Z axis steppers. I'm gonna just plug a random stepper and test it just holding it in my hand so I don't have to tear the printer apart. If the config is good then the only thing left is the wiring and the motor. I've bypassed the wiring with a new one so I'm certain its not the wiring. I'll get back with ya. Thanks for the reply...both of you.

@SonnyD1 said in Configure 2nd Z Axis Stepper:
M350 X16 Y16 Z16:16 E16 I1
Remove the second 16 value from Z. You only need to set it per axis, not motor.
Can you share a photo of the wiring at the duet side just to confirm which drivers you're actually using?

@Phaedrux
Not sure if you can make it out in that mess. Working progress and all. They are plugged in as follows:
X axis - Xstep
Y axis - Ystep
Left Z - Zstep
Right Z - E1step
Extruder - E0step -
SO I think I've managed to isolate the issue. I tried another stepper I had that I know works on the same driver and it did't work either. So I tried that motor on the one that I know that does to confirm. The wiring is good and all motors are good. The only thing left that I can't check is the driver. Is there a way that I can confirm that I have a bad driver?
-
Do you get any error messages after trying to move the suspect driver?
Can you share the results of M122 after trying to move the driver?
Did you remove that duplicate 16 value from M350? -
@Phaedrux I don't get any error messages when moving the Z axis. One motor (Z Left) moves and the one on the right does nothing. I've confirmed that it's not the motor or the wiring by running both motors with both cables on the Zstep driver. I cant get anything to work on the E1step driver. I removed the duplicate 16 value from the M350 line before running the tests. Here are the results from the M122 taken immediately after tests:

@moth4017 I've isolated the issue to the E1step driver that my right Z stepper is plugged into. Swapping wires and motors the fault stays on the same driver. I do not have another driver that I can try.

When and where did you purchase the board?
-
@Phaedrux I ordered it from Filastruder on June 13 (#95005). I had some life events come up which is why I'm only just now working on it.

@Phaedrux I did as you advised and sent that email. I haven't yet received a reply.
