Ok, new hot end sensor, the control board is back to 12v
I'm still getting the error, but it's not every time, sometimes the printer can run for 25 hours (about 4 prints) before getting the min temp error.
other times only 2 prints.
Would I get this error if the hot bed temp gets more than 2 deg below set point ? or is it only for the hot end?
what else should I look at to fix this problem ?
