Bit of an odd one I'm having trouble with.

I run a single extruder, generally E0. I swapped in a new extruder stepper and now when I send any extrusion signal the stepper just locks up until I power off the machine. I have tried the following:

• Changed to E1 to see if maybe it was the driver that's bad, but E1 has the same issue.
• Tried other known-good steppers in it's place, same result.
• Ran M584 X0:3:4 to mirror the X axis, when I move X the extruder stepper turns just fine and seems to mimic X perfectly.

Nothing has changed in config.g prior to me swaping E0 and E1 (back to E0 now)

What would cause the stepper to lock up an force a power cycle yet M584 X0:3:4 works?

Thank you for the help!

It's all nice and secure, Vin stays right at and sometimes slightly above 24.0v

Only had this problem about 3 times in a row then now its running fine again.

Dang, thank you for the help!

It's a new meanwell, I tried not to skimp on the psu.

Hello all,

I've recently built a second printer and went with a Duet wifi for the build. So far I've put maybe 100 hours of print in it with no issues however now I'm getting random resets mid print.

Things will be going well then I'll hear the click click click of the bltouch doing it's startup self test. That's when I find the printer just stopped. The M122 is below, any help would be fantastic. Thank you!
