So, I know I’d need to code and compile this myself, just wanted to feel out the idea.
My printer currently lives in a detached garage with no heat or AC. Power is controlled via smart switches and filament is left loaded, stored in a desiccant box above the printer. So it works great that I can start prints without ever leaving the house…then go pick them up days later or whenever.
Except of course when its very cold…below freezing, etc where the printer is sitting below MINTEMP. One option would be to add some sort of external preheater to another smart switch to warm everything up…and to be honest, this is probably the best option. (Filament gets a bit fragile when its cold too.)
But I was also thinking about a modification to the thermal runaway protection. Do you think it would still be “safe enough” if instead just insta-kill at MINTEMP when the heaters are first turned on, it allowed it a short time to show a temperature rise? If no rise, then it kills. And if the temp drops to MINTEMP when the heater is already running normally, also kills.
Just lets the heater get started for a short time when its very cold, and then resumes normal protections after the allowance window.
Would that be reasonable? (Not asking for this to be done for me, I know its an edge case.)
