How do you reset it?
I warmed it with my hand to about 15 degrees but when I power cycled it, it still said "min temp error"
// The minimal temperature defines the temperature below which the heater will not be enabled It is used // to check that the wiring to the thermistor is not broken. // Otherwise this would lead to the heater being powered on all the time. #define HEATER_0_MINTEMP 5 //#define HEATER_1_MINTEMP 5 //#define HEATER_2_MINTEMP 5 #define BED_MINTEMP 5

On my replikeo duet0.6 I found 1k pullup resistors, which got me in trouble with temps below 15°C. RRF_DC42 firmware has no parameter to set min_temp.
I use body heat and a fire lighter to raise temp then reset the controller.

That's very cool! No, wait, I mean it looks very warm.
I'd be just a little bit worried about a radiant heat element in there, it may tend to produce hot spots on anything that gets close. I'd guess that a small oil filled convection element would be a better choice, although a quick search on ebay completely failed to find anything suitable

The heater is currently controlled from an external controller, but planning to use E2 thermistor and an SSR for it at some point.
I'm not sure you could control the SSR, when you have a min_temp error on the two other thermistors?!
