Hello,

I have a problem with the heated bed. I can’t seem to get it to work. The extruder gets up too temperature, and the thermistor is reading what I think is pretty close. I switched therm 1 with therm 2 and get readings from the heated bed thermistor. When I turn the extruder heater on, heater 1 LED lights up(LD3?) but when I turn the heated bed on, LD4 doesn’t light up?

Any suggestions?

try to switch thermistor

I get a reading of the heated bed when switching extruder sensor with heated bed sensor, so I figure the thermistor works?

Hello cdonnelly,

I have same issue as you do.
Tried switching thermistors and on extruder I get both readings, difference 1degree, which means thermistor is fine.

What else can be checked to sort this out.
