Can you send M122 and M98 P"config.g" and post the results?
Can you also post your homeall?
Does G30 by itself work to use the probe?
-
Yes the probe works by itself. Posted results below:

What is the U axis? You have two endstops defined for Z, but only a single driver. You have two drivers assigned to U, but only a single endstop.
You also seem to be referencing a V axis...

@phaedrux U axis is an external carriage for thermoforming. What is a driver in this case? One end stop on the U was intentional as it doesn't need to be very level.
Whoops the V's should be gone, the firmware was copied from an old one to start which had a V axis. Looks like I missed a few!
-
You can only use independent Z motor leveling with 2 endstops if you are using 2 independent drives for the Z axis.
-
@phaedrux Ohhh, I see. So I can't use both the Z drive connections, the other has to use a different driver.
-
The 2 Z motor connectors on the board are wired in series to the same driver. To get independant control, you'd need to use a second driver for the second motor.
See here for more details.
https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_auto_levelling
You're on the right start. Once you fix up the driver mappings and clean up the U/V stuff it should work.
-
@phaedrux Awesome! Wouldn't have figured that one out for a bit
should be an easy fix then, thanks for the help. -

Here is my new config.g with updated driver setup and elimination of V axis. Made sure my end stop wiring corresponded to the drivers in the same order as the pin call out "zstop+e2stop" as well. I'm still getting a G28 Z Failed to Enable End Stops, error message.

G28 Z Failed to Enable End Stops, error message.
You're only getting that error when you send G28 Z?
Does homeall work?Can you send M119 and share the results?
Can you send M574 and share the results? -
@jrcl said in Independent Z Motors- Endstop Error:
M574 Z2 S1 P"zstop+e2stop"
I suspect that line isn't working as intended. As you have a DueX in the system, you should use this:
M574 Z2 S1 P"zstop+duex.e2stop"

@dc42 Aha! That fixed the problem, Z is homing as expected now. Thank you!
