Yes,i know yours is plastic,i post it just for giving you a reference to dismentle your extruder...

ok ... unfortunately I have no Teflon and what I need as yet. This printer is new and therefore I have no spare parts here. Please can you this send?

Hey，buddy
Sorry to bring you the trouble.Was your nozzle diameter set the same as your nozzle's actual size in the printing settings(cuz i knew about your nozzle size is 0.3mm from our sales,and this setting will make a difference)?

If these are corresponding size to your nozzle and it doesn't work yet,then you can ask our seller for the replacement of Nozzle Throat & Teflon PTFE.

I now once again checked through everything and have found that the filament is not tranportiert. the filament is not pushed through this wheel forward see video. I can filament as by pushing calibration times .. that probably should not be so right?

I saw your video carefully.I found the wheel(what i attach) didn't ronate when you moved the filament through it,am i right ?It seems the gap beween the two wheels is too large etc...How do you think?

yes you are right i can push the filament without the wheel rotate ! Although, if I do this with the engine built state rotates the gear from the motor but the filament remains on the spot.
