Over temperature TMC2209 error even with replacement TMC2209
got a GSTAT error the other day. So swapped to higher flow fans on my BTT Octopus Pro 446. Ran two big prints without a problem.
Last night, than again today got over temp errors again from stepper_y. IR temp sensor says yes, stepper driver _Y was definitely hotter than the rest (~55°C diff others at ~35°C... yes cooled a bit after shut-down after the error state that stopped the print) Checking the motors, Y was actually cooler to the touch than X. So examined the wiring. No detectable issues when ohm-ing them and jerking the connectors around (no opens or shorts). Same for the motors themselves. (ohming)
the error didn't appear to show up in klipper.log (see attached)
This is stock RatOS (not 2.0) high perf stepper configs, BTT TMC2209s with the larger heat sinks. I'd already backed down the motor currents to 1.5A well before ever getting this error.
What I don't understand is it's the same Y stepper, even after replacing the TMC2209 in the socket on the BTT Octopus Pro 446 popping up this error. What should I start probing/looking at? Electrical is my bag to begin with so no problem digging deep into the hardware.
(how do you attached a .cfg or log file to these posts)
Ideas? suggestions? HELP!
