Duet 3 Mini 5+ Short to Ground Error

@3dmakerkid said in Duet 3 Mini 5+ Short to Ground Error:
I have heard that there was an issue with a revision of the board awhile back with this issue, so I'm not sure if maybe my board was a part of that batch?
I think you may be referring to the Duet3 6HC which had a batch of bad diodes, but I don't think that affected the mini.
Are you using stealthchop?
Can you send M122 and share the result?
@3dmakerkid said in Duet 3 Mini 5+ Short to Ground Error:
Often accompanied by this error is the X or Y axis refusing to move and making an intermittent ticking sound (X is plugged into driver 0 and Y to drive 1).
I assume you've checked out all the wiring?

@phaedrux I am using stealthchop, M122 result:

I think it may be related to stealthchop. Can you test with spreadcycle for a while?
-
@phaedrux Yes, I can.
-
@3dmakerkid actually, Does sensorless homing require stealthchop to be on? I can't seem to recall
-
I think stallguard works with stealthchop, but I don't think you need stallguard configured to use stealthchop.
Additionally, the TMC2209 stepper driver used in Duet 3 Mini 5+ (and Duet 3 Tool board TOOL1LC once stallGuard is implemented in firmware), features stallGuard 4. This is optimised for operation with stealthChop, while its predecessor stallGuard 2 (TMC5160 and TMC2260) works with spreadCycle. You will need to adjust the speed at which stealthChop changes over to spreadCycle. This is set by M569 V parameter. The default is 2000.

@phaedrux Ok, I'm using sensorless homing on this printer and it looks like it can't be used with spreadcycle, as I found out here https://teamgloomy.github.io/sensorless.html .
-
Well you'd switch between as needed I guess.
Stealthchop isn't really recommended for printing unless you're limiting your speed and acceleration due to the loss of torque in exchange for absolute quiet.
-
@phaedrux It's now doing the same thing as before except just when the machine is powered on instead of after a print, and I changed nothing. So I'm not sure how much switching stealthchop off is going to help in this case.

As we can't rule out whether there is an error with the stepper or not, we will replace the board under warranty.
Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.

@phaedrux You guys are awesome, I'll get that done as soon as I can!
