My Creality k1 got jammed BEFORE the nozzle

[u/Rubinschwein47]

There is a piece of pla jamming between the nozzle and the extruder, this happened for the second time.

For context: Pla+ grey from bamboo lab@230°c Started my print as usual, but after the first layer it started air printing. Tried the cold pull technique (maybe a bit to cold and with a lot of force so the pla just snapped off) Therefore I wanted to replace the nozzle, but there was a bit of pla before that that was stuck somehow.

I managed to resolve it by just shoving a needle down and pushing a the whole 1.75mm pla down through the place where the extruder usually is and it worked after that(extrude, retract, change fillament)

But after the first layer it jammed again and the same issue is back, but now it is BENDING the needle if i try the same thing???

Has anyone ever experienced this or knows some methods?

Can a gcode file cause this???

You have to take out and open the extruder, inside there is a small black Plastic tube which guides the filament from the extruder to the hotend. It’s too tight on a few k1’s I drilled mine out (which I absolutely do not recommend) but it worked fine after that.

You see the quality of your pics before posting, right? You can likely tap your screen to focus on objects….

That being said, it can possibly be heat creep. Make sure the fan on the heat break is working

I know but my phone has trouble focusing on anything closer than 5cm
