Duet 2 Wifi Bad Drivers
-
@Chris2010 there are glitches in your config, eg you use drive 5 and 9 for the extruder, but dont have a M569 definition for it. U uses 4 microstepping, but Duet doesnt support interpolation for it, only for 16.
Datasheet says 2.0 A maximum for the xy steppers 42sth60, so current setting is too high, should be 50-85% of it. At z position the current was set lower, this may explain why they work there.
-
I could if its necessary, but that would require removing the whole board from the machine. Would you like me to do that?
-
Well if the drivers are damaged you'll have to remove it from the machine to exchange it, so...
-
@JoergS5 Im planning on installing another extruder shortly. I can lower the current on the steppers but as its not moving at all, that seems like its not the issue? That should be a factor for overheating but as far as I can tell they aren't. Is that correct?
-
@Chris2010 i had too high current once at a stepper, they dont move then and heat up. its worth a try.
-
@Phaedrux Great point lol. And Ill give lowering the current a try. Thanks for the suggestion!
-
I don't think there is any extreme error in the config. At least none that should generate the problem observed.
Mainly you're missing M584 to create the U axis.
The current is high for X and Y, so worth a try reducing it, but I don't think it would generate the issue seen.
-
I might also suggest getting a fresh config from the web tool with just the basics. No Duex connected. Just the default drivers defined and test that.
-
@Phaedrux Thats a good Idea as well. Guess Ill try that next.
-
So XY currents were dropped to 1560 mA and retested. No luck. Still no movement. On to the new config test...
-
Ok, retested with fresh config, Z moves (connect to tool lock) X and Y do not. It looks like the drivers to me. Any other ideas?

Please contact filastruder and initiate a warranty exchange for the Duet Wifi. Link to this thread as authorization.
I'd still be curious to see photos front and back when you get it out.
-
When RRF reports both phases of a driver may be disconnected, it's rarely a driver issue.
Are you sure you have identified the driver numbers correctly? Your photo of the Duet WiFi shows a motor connected to the Z driver, which is driver 2, and nothing connected to driver 0 or driver 1.
-
You are correct it seems odd to me about the drivers as well, but the pictures posted didnt show the 0 and 1 drivers. Here is a pic of that. Again, the motors for X and Y worked when plugged into Z but not on their respective spots.
-
Ok so here is the removed board front and back. As far as I can tell there are no bad solders or visible damage.
