hi peggy
thanks for your reply. yes, everything described above is without the feeder, pushing the filament in above the print head by hand.

Just to be sure. (For what you say you already check this). Ptfe isolator coupler deform? Brass heat barrel inside the peek in good condition? No previus leak from coupler or nozzle/barrel that could go carbon and make solid overtime?
hi neotko
as far as I can tell:
- ptfe isolator in good condition, I can't see any deform, but will check again
- brass heat barrel seems to be fine, although it's not shiny brass anymore (normal I guess?)
- no previous leak, I installed the new nozzle maybe 6 months ago, no problems so far
Have you do an external test to see how really hot it's the nozzle. Maybe, just maybe, the heat sensor says one think but the heat it's different. I think @gr5 use to post that for um2 users but I can't seem to find his posts. It's one about moving a pla peace near the nozzle to see how it reacts or something about placing a water drop to see if it boils and banishes.
I think I should test that. maybe I can find this post. one maybe important detail: I tried to increase temperature to see if that would help. Is it normal to get a max temp error at 275°C?
edit: I just checked, this is indeed the maximum, so this shouldn't be a problem
Edited by GuestMaxtemp it's by marlin limit. But that still doesn't mean the heat reading are accurate. Ofc if everything else fails could be the barrel to be with burned material overtime and making your filament to stick at somepoint.
I would try to take out the nozzle and pass filament. Ofc do it manually so you can avoid the huge cleaning on the aluminium block. But first check the temperature to see if it it's really heating.

did you feed the filament by hand or turning the wheel on the back?
can you try to push the filament through by hand without locking the feeder on the back?
Can you check the little black wheel in the locking part on the feeder? If it is turning freely and has no damage?
