Hi, I have had a cr-10 for about a week now, and have been very impressed with my first 3d printer.
To get away from the noise, I have relocated it to my outside unheated shed.

I did a print last night, and when it was finished I went to remove the part and saw the minimum temp error. Didn't think much of it, but this morning I tried to run another print but it wouldn't let me because of the same error. Both bed and nozzle temps were reading 0 degrees C. Ambient temp was right around 0C.

I am assuming it is a failsafe, and that the controller must see a minimum temp somewhere above 0C before it will try to run the heaters.

Does anyone know the minimum accurate reading of these thermistors? I'm wondering if I can change the firmware to allow for a minimum temp of -5 C or so.

Thanks.
