I think I did a terrible mistake. I put a 12 V 30 W hotend thermistor (replacing the original 24 V thermistor). It worked (I set the temperature to 90 deg C, just for testing, and worked), but when I changed back to original 24 V thermistor the temperature does NOT go above 160 deg C (!! big surprise for me). It is not a tempsensor failure, not a firmware bug. I think is the worst that can happen: the current pulled from the board was to big ( ) and something burned. Can you help with any advices ? I already wrote to DMS, if nothing can be done I will order another board.
I didn't think the thermistors came in voltages? They change resistance according to temp and are rated in ohms. Our boards use 100k ohm varieties, I have a pack sitting right here. Does anyone know different?
Hello. I solved the problem: when I mounted my E3d hotend I left no space between hotblock and cooling part. So the heat went from hotblock directly to the cooling part. In this way the printer hotend can not reach the setted temperature. I googled and found the answer: the air separation between hot block and cooling part is very important. Is good to know.
