3d Printer Hot End Temperature Fluctuation

This component of the extruder is responsible for melting the filament so it can be forced through the narrow opening of the nozzle.

3d printer hot end temperature fluctuation. So far in my other printers i only use the old school 100k thermistor both in a e3d v6 and some other hotend and it is much more stable. When it gets around that temp the fan starts and stops spinning at least 5 6 times during every cool down and the temp fluctuates at least 5 degrees. First layer usually 50c 100c higher than subsequent layers. Glow in the dark use 50c 100c higher.

The hot end is basically a heating element integrated with a heat sink a heat break and a thermistor. I double treble checked id soldered to the right connections. Fluctuations up to 100c around the target temperature during preheat and printing is normal. The printing temperature is one of the most important settings in 3d printing especially when changing from.

Sometimes it is too hot the other time it is too cold. I did the fluctuation hot end mod and afterwards the base plate heater is permanently on full temperature.

Heated the hotend to around 215 and tightened the nozzle then turned the printer off. Upon initial heat up atom firmware has a proportional integral derivative pid control algorithm that takes over temperature controls when the temperature reaches within 100c of the target temperature to help it stabilize. Dropping hot end temperatures can be caused by the filament cooler blowing too much cold air onto the nozzle or a too high of a print speed so that the nozzle is cooled by the filament in combination with a heating element that cannot heat that fast to compensate. After all it remains a plastic process in which temperature is an essential part.

8 put the extruder back together closed up the case to the circuit board and rewrapped the cables. 3d printer temperature is an essential setting for success. With 3d printing it is actually no different. Pla can be printed both with and without a heated print bed but if your desktop 3d printer does have a heated print bed it is recommended to set your print bed temperature to approximately 600c 8 00c.
