Driver 0 only moves in one direction
-
How did you have driver 0 configured when you were testing? As an extruder?
How were you commanding movement? -
@phaedrux
I'm using the DWC dashboard to command movement. I've also tried G1, stepper still moves in one direction even if I tell it to go in the other direction; it's very strange.Yes, I had it mapped as the extruder, just so I could use Extrude/Retract to easily move the stepper to test the functionality of driver 0.
I'll also mention that I've been using this same dual-z setup for a few days now with no problems whatsoever.
Also, sorry, I don't know why I didn't think to include my original config. Here it is:

After further testing and troubleshooting, I am still unable to fix the issue.
I am currently back to using a single z axiz motor, but I'd like to be able to use both. -

@fcwilt Yes, I used an entirely different spare stepper I have attached to driver 0 and I'm still getting the same problem.

Then I would guess that the driver chip has failed.
You could as a test swap the assignment of X+ and E in your config file and swap the connections on the board. You could then test for correct X axis operation.

@exquisite Do you have any way of checking voltages on the board?
It would be at least INTERESTING to check the driver 0 DIRection pin and see if it switches between forwards and backwards.
A volt meter would work.
The SCHEMATIC says there's a testpoint TP12 that is the Dirver #0 DIRection signal. Try moving forwards and backwarsd and see what voltages you get (with the other probe on ground)
-
@alankilian For sure, I'll gladly check that when I get home Tuesday. That would be fairly interesting to me too, I didn't even think to check that.
-
Alright so I cannot find my multimeter, so I am unable to check the output of the dir pin.
My issue still stands though, driver 0 seems to have developed a fault that I cannot resolve.
May I request a warranty replacement? -
when and where did you purchase the Duet?
-
@phaedrux
I bought it from Filastruder on Dec 13 2021. -
Have you tested with a motor with the shaft completely disconnected from any resistance?
-
I tested Driver 0 with a spare stepper I have that's not attached to anything, completely resistance-free. I still get the same result. If I tell the stepper to go right, it goes right. If it tell it to go left, it still goes right.
I know my spare stepper is good because I tested it with my old MKS Gen L.
