Pinter Stops convey fillament through Extruder

Hello :slight_smile:
i have a new Problem with my Pinter.

As you can see on the picture, the fillament cant be pushed through the nozzle.
The Printer was working for about 3 Hours and then it Stops extruding fillament but the Printer was still moving. The Extruder wheel (that conveys the fillament to the extruder) was also still turning, but it rubbed off the fillament.

It Stops extruding the Fillament and i think its because the Extruder doesnt heats up to the Temperature it Shows me on the Hyperpixel. is that possible ?
At the Moment i could just measue with a Pyrometer the Nozzle exit and it Shows me 170°C, while the Printer is Set to 230°C.
Ive never measured the temperature at the nozzle while everything was working well - so is this difference normal ?
And is the Temperature shown at the Display from the Printer a real measured temperature ?

Or do i have to teardown the extruder - maybe there is something Stucke in it ?

Maybe you can find something in the log Files.

Attached pictures of the fillament after i pulled it out of the extruder.
Logfiles (are to Big, so i had to use my Dropbox): Dropbox - Printer Forum - Simplify your life

thanks in Advance

A clogged nozzle can have different causes. Maybe it's some debris in the way.
Also, the outside temperature of an hotend can differ from the inside temperature.
These thermistors are quite reliable as long the correct parameter is set in the firmware.

In all, it's a printer issue, not one of OctoPrint.

BTW: If you have printed with higher temperature material before (PETG, ABS etc), some of that can clog the nozzle too. Heat up to a higher temp (250°C or so) and extrude again to remove the remnants.

Thank you :slight_smile:

can you rcommend me a good Forum for questions regarding Printer issues ?
Im quite new in this Forum thing so need Held findinga good one for me...

And for removing the clogging, i have to teardown the extruder - is there a YouTube for that ? :slight_smile: ?

I was just printing PLA all the time and raised the temprerature to check if it will also raise on the nozzle :slight_smile:

I'll recommend :
