I've been trying to print and every time I want to print, right after it calibrates it tells me ERROR: MINTEMP BED and right after will say MINTEMP BED Fixed Please Restart and I will proceed to do as says and then it repeats the same process and says error. What is the problem? Ive updated the firmware and cleaned the entire bed from dust with alcohol.
You probably have a broken sensor cable. You can measure the resistance of the cable. It must be around 100ohm.
Had exactly the same. Bad wire and ordered a new bed sensor.
it is possible to cut the bed thermistor wire under the bed near the cable clamp, and inside the Eisy box, near the cable clamp, then replace the middle section of the wire, with new wire, soldered and insulated in position, then re fitted in the braided cable covering... the thermistor is not polarity conscious... (Use thin, multi stranded insulated wire, long enough that the repaired cable is as long as, or a little longer than the original)
this will usually resolve the issue
