It appears that a panic is possible with the MK4S due to increased cooling. When heating above 80 degrees and cooling above 60% (e.g. the default 90% in OrcaSlicer) the heater bed cannot maintain a the temperature, and starts dropping.
For safety, the MK4S panics as the temperature is dropping while the heater is on.
Example of this inability to maintain bed temperature.
How to reproduce
The standard PETG temperature tower generated by OrcaSlicer with a max fan speed of 90% and a bed temperature of 90 degrees.
Expected behavior
I would expect no panics to occur when operating within the design limits e.g. fan on at 100%. If nothing else, this should be documented (as IMO, any panic should be diagnosed).
