Hot end always ON!
Posted: Thu Feb 15, 2018 5:07 am
Anyone know what is the problem with my HE280 hot end:
When I power on my Rostock Max V3, hot end starts immediately with red light ON and warming the heater cartridge.
Termistore measure right temp, but I cant stop warming the hot end.
The problem started during the start on a print, when bed was right temp and hot end was warming to reach the right temp.
I thing the heater certridge is good beacause it warms hot end.
I think the thermal safety fuse is good because otherwise heater cartridge not warm.
I think the 100k thermistor is good because otherwise display dosn't increase hot end temp.
So what is it??
