i have a problem with the feeding of the filament, it wont push true the nozzle verry good,
i removed the nozzle a couple of time to see if nothing is blocking it als replaced the little tube thingy a couple of time in different sizes but the problem still keeps happening , i raised the temp even up to 240 to test it out, when it starts feeding it goes for like a couple of sec then it blocked.
Tried the extruder also first to see if the problem is not coming from there but when de pla is removed from the hotend and i extrude it goes very smooth, so the problem must come from hotend and nozzle
it is very frustrating since i tried it like 4 times now with no result,
i had the k8200 aslo before and i had to buy the e3d v5 nozzle for it to make it work decent, its a bit a shame that on the vertex printer the nozzle is also of the crappy kind causing millions of problems , pls in the future replace the crappy nozzle and hotend with an e3d one i am more and happy to pay an extra 70 euro for that and not having to struggle to get 1 good print
i hope there is someone here that can help me out to fix it
Check if the stepper for the feeder is giving a ticking sound or if the feeder is grabbing the filament hard enouph. There can be 2 things that i know of that can cause the symptom. 1 is that the feeder is screwed to hard making the lever to slack toward the feeder Wheel. the other is the stepper driver current is wrong making it tick when it need to press on the steps. Basecly it is missing steps. Have you done the stepper driver current calibrations?

wel i dismantled the feeder and the hotend , the feeder should be ok everything works fine until i put on the nozzle then the ticking sound comes back , out of fustration i ordered the metal hotend online its just a shame that there are always problems with the hotend and nozzle and eventually you need to buy the metal one to make your printer work like it should, had the same with my k8200.
like i said before i would prefer to pay an extra 70 euro on the printer that has a high quality hotend and nozzle that does have min clogging than have to order it myself and paying more with shipping and al +i have to wait until i can use my printer now
Instead of raising the temperature, you should lower it. The real temperature is way higher than the displayed one so you’re burning the filament in the nozzle (or it soften and makes a blob before the nozzle entry).
Could it be that the small hole on the upper side of the peek isolator is partially causing this problem?
After some improvements of the printhead i have barely problems when printing (only when I set retracting to a high value and printing PETG filament) but somtimes problems by unloading filament. And the problem is allways the same: The filament inside the teflon tube has a little bit bigger diameter then 2mm (I mesured the end of filament after pulling it out by hand) and the upper hole in the peek isolator is exactly 2mm I think by the rising heat the teflon tube widens just a little bit an so does the filament in the tube.
Next time I will widen it to 2.1 or 2.2mm for testing.
Also I recognized that there could be a little misalignment between the 2mm hole in the peek part and the hole in the coupler because there is no guidance. I aligned it by insert the upper end of a 2mm drill before tightening the screws.
It might be a different issue, however here is my experience :
I had much blocked nozzle issues, I installed a filter (on thingiverse) just before the feeder which probably got rid of dust and small bits of filament.
Have not had a problem since, yesterday I just finished successfully an 18+ hours print job
