Extruder Temperature drops 10c for 1 or 2h
Hi,
i just discovered a problem. In all my prints the temperature of the extruder drops around 10c from the selected value. For 1 or 2 hours and then goes back again. I tried it different filaments. Anyone else have this issue?
Thanks,
Daniel

Re: Extruder Temperature drops 10c for 1 or 2h
Are you using the standard prusa part cooling fan? i.e. is it possible that the part cooling is blowing too much on the heat block? Does the hour it goes low coincide with the part fan going to full blast or blowing into a closed volume and coming back out at the heatblock?
Are both the thermistor and heater tight in the block?

Hi,
yes all standard and tight mounted. Its strange because it will go up again after that 1h and then stays at the correct temperature till the end.
