MMU Extruder Target Temperature is Zero
I have on several occasions seen the extruder target temperature set itself to zero, but the MMU still attempts to load to the cold extruder as if everything is normal. Even if I pause the print and manually set the extruder to the correct temperature, the target goes right back to zero when I resume. I've lost several long MMU prints this way, as there seems to be no way to recover.
As a software engineer, I can recognize that this error occurred because the programmer made an assumption somewhere about the extruder temperature being what it was "supposed" to be, but didn't bother actually checking it. I hope this is enough information for the developers to find and fix the bug.
