Feature request(?): Move Z on THERMAL PANIC
Hi @all,
tried /just for the heck of it/ ABS the first time with my MK3S Kit:
designed some simple part in Tinkercad, duplicated it and set Filament to "Generic ABS" (E:250 / B:100 seemed a bit high, especially on the E-side but ...) in Slic3r PE -> and off we go.
OK: Primer-Line + <the thingy drawn around all parts>
OK: Layer1 of Brim, Outline & Infill of Part1
NOK: Printer stopped with "THERMAL RUNAWAY" on Part2 (some light smoke, Part1 got "a bit white")
Outcome: no damage on E3D as far as I can see (changed to PET and the following 2hr-print came out just fine);
... just a tiny little "dot" on the steel sheet which makes me wonder if <firmware> should raise Z -say ~5mm- if this error happens...
I do not see a problem with this:
the print is b0rked anyway, if this happens near Z-MAX it will be -hopefully- caught by the stepper-controller and the motors will power down; nothing [bad|worse] can happen here.
I do know the CNC-Mantra of "in case of ESTOP *do* HALT everything, don't faff around" but I do not think this should apply here.
What are your thoughts about this?

Second that.
It was my experience today two times and would really be great to have it rise.
But, my printer said: bed preheat error. After two layers. Idk why, it raises temp to 110deg after the first two layers and just can't. I'd really like to know why.

Same problem with ABS on my Mk3 using both 3.6.0 and 3.7.0. Getting really frustrated with this. Going to revert to 3.5.2 to see if that helps.

Hi @all,
would be nice if Prusa responded to this one.
BTW: I think I found a bug:
-) Started a 12hr-print the day before yesterday and left it running unattended after ~3 hours (hey, I've *got* to sleep sometimes ;-))
-) of course filament at about 90% of the print
-) the MK3S moved to "front right" and patiently waited for me to feed it some more
-) in the morning I <clicked>, waited for heat-up, fed it the new spool + confirmation re colour etc (can't remember the exact woring)
-) printer proceeded to "last position on the part" and and I got a nice "THERMAL RUNAWAY"
🙁 this is me posing as sad panda and I *really* think that errors of *any* kind should abort whatever the thing is doing / waiting for.
Also I still cannot figure out what is causing my runaways, they a) only seem to happen with long-running prints and b) give NO indication _what_ ran away (Bed or Extruder?) and I really do not want to faff around with the cabling with a hit-rate of 50:50.
PS: the new forum seems to be a ...nice... way to waste screen-estate but that might just be me.

Not saying this is why: I am only curious.
Have any of you done the PID calibration for the nozzle heater?
ps: (at the high temps you are printing at)
RE: Feature request(?): Move Z on THERMAL PANIC
ayup, been there, done that.
/no difference
EDIT:
just as a reminder: how does one do this for -say- ABS @E:250/B:100?
