hi everyone
im having a strange problem with my 3d printer
i pre heat the nozzle to 250 to change the filament
and today keeps sending ,heating stop heater _id :E0
any ideas
ive already change
heater element
thermistor
What happens if you set it to 220?
if i put 245 it will heat up fine and nothing will happend
but more than that will trow the error code
So why not do 245 for the change?
i was thinking that so i try to print in that temp
and the filament dosen come out so i tested the nozzel
and iwas below 200 so it dosen maintain the original temp
Hi Liam,
If you have a full metal hotend you may need to look at the safety settings in your config to see if the manufacturer says its can go above the temp you want to print. But if your hotend has a different material in the heatbreak (this was an older type), it may not be able to safely print at higher temp.
Also, if you have a nozzle jam, it may not help to print at a higher temp. 250 is pretty high for PLA, although ASA, ABS, PETG could probably all tolerate it. What material are you printing?
If your nozzle is currently jammed, it can help to do a cold pull. For PLA I like to pull at 160-180 depending on the circumstance. The goal is to have it soft but not liquid so you get more material out (at least in theory.). Other filaments would have different temps.

If you have replaced both the heater and the sensor, then maybe it is your power supply or your board heater circuit or even the new heater. Do you have another 24V supply you could try?
Are you running 12 or 24V? I once bought the wrong heater and the 12v heater burned up running at 24 V after not much use. Maybe verify that as well.
I just picked up an ender on Thursday (way too cheap) and the previous owner said it was having heater problems. The heating cartridge wires were corroded at the hot end and the cartridge wouldn’t slide out. The thermistor connection at the board wasnt all the way plugged in and the sensor itself was a style had never seen on a 3d printer. There were a few splices in the wiring I removed as well.
After replacing the hot end and adding a mount kit to move the extruder over the hot end for a direct-drive setup, a quick clean and level, it is printing fine and destined for a friends house next week.
