Octopus or stepper or drive, not sure which but something is broken.
Hello All
Hope you doing well.
Came down to the printer yesterday, and it had stopped mid print. The display was not showing, but it had some light. I power cycled the machine and the BLT didi its test thing.
It has a bit of a "The Magik Smoke" smell to it.
I think I have fired a stepper. but only 1. What do you think?
This is on an octopus board.
When I turn the RHS Z stepper with the machine powered on, if feels like it is "breaked" / Has some current.
Non of the other motors do.
If I power off its fine.
So I pulled the drivers off for both Z, and was still the same.
So maybe a bad stepper?
Please see attached klippy log.

So this is the damage. New octopus on order, and some steppers to replace (not sure how many yet)
After replacing the damaged steppers klipper will connect but as soon as I home there is no motion and klipper freeks.
Is 5hus the sign of a dying stepper? Or just not enough cooling in the electronic cabinet?
over current setting and or cooling. but normally, Klipper should have shut-down with a GSTAT error if over temp'ed. Since that connector is fried,,,Id say over heated enough to have solder melt and shorting motor supply voltage to nearby components. Since the TMC chip itself is smoked...it was defintely a short.
stuff in RED looks all charred.
