Min-Temp Bed Error

Is there a way to disable the Min Temp Error? My Mk3+ printer is in my garage which has background heating to 10 degrees C.  Every time I turn on the printer it refuses to start due to the temperature being too low. However when the temperature falls further to 0-4 Degrees the firmware does not register the temperature as too low and the printer heats up and prints perfectly. Can we not turn this function off or have an over-ride facility on first start? Otherwise i have to hold my hand on the bed and nozzle for 5 mins before the printer works!! There must be a better way to determine if the thermistors have failed?

RE: Min-Temp Bed Error

Yes, there is but you don't want to do it. It's a safety feature that is necessary because the thermistors used are inaccurate at low temperetures. Thermistors are very simple devices that change their electrical resistance with temperature change, so no there isn't a better way.

I'm very interested by you finding that error not triggered at 0-4C. I'm sure one of the clever people on this board can explain that.

Joan suggest a cup of tea placed on the bed, just to get things started. Perhaps a better long term solution is a heated enclosure.
