H2D start G-code seems to use a blocking G150 trying to cool down the nozzle below chamber ambient temperature, when chamber is ≥40 °C. This causes infinite wait during homing for ASA/ABS. Reproducible at chamber 65 °C. The problem is when there was a print going on and the chamber still hasn’t cooled down from the previous print (I don’t see the need to cool down the chamber between high-temp prints, waste of energy and filament seems not to be an issue for BL)
A reply to myself:
It was due to plate offset failure. I pressed “Ignore” hoping it really meant “Ignore”
However, some firmware macros took over and they made it stuck in loop. Waiting to reach 60 degC when the chamber is already 65 degC.
It should be fixed. Although fault, it should be more graceful than capturing your printer in a heat loop. Might as well happen with any non-recognized 3rd party print plate.
You can reproduce it if you ‘offset’ your plate so that offset detection fails. Press ignore with ABS/ASA, and witness the bug.
