M175 on Taz 6 Thermal Runaway

General

Hello,

@Wrathernaut - using your firmware and things have been printing well.

I had a print abort due to Thermal Runaway in Octoprint recently.

I just went ahead and inspected everything on the Universal Adapter and wiring - looks good.
It felt awful warm when the print aborted so I don’t know if that’s from being in the enclose and above a heated bed (and hot end).

I just redid the Hotend PID -

DEFAULT_Kp 24.51
DEFAULT_Ki 2.25
DEFAULT_Kd 66.76

I had the printer do a few minutes of material purging and no problem.

I just launched a new print and will see how that goes.

Anything else I should inspect?

I never experienced thermal runaway with that firmware, but my environment likely doesn’t match yours. It might also be the PrusaSlicer profile I use which brings the cooling fan on more gradually so it doesn’t bounce off the bed at lower layers.

I’m now running a new build of the firmware that’s more tailored to my setup even further and takes advantage of the newer features of Marlin. Since I’m going through Octoprint for everything, there’s no longer SD card support, and I’ve moved to UBL for leveling (10x10 mesh with 3-point tilt) and MPC instead of PID for the hot end.
