Hi All, we just got this thing a few weeks ago and now the nozzles are unchangeable almost.
Extremely hard to thread on and off.
I don't see the threads inside the machine with plastic on them, looks clean. I tried some acetone on a q-tip. Looked clean. Nozzles are clean - I atomic clean them when I swap.
I don't see any damage to the nozzles or the internal threads, meaning I don't think there was any cross threading here.
If there is damage its extremely minute.
Just curious if anyone has experienced this and if the part of the print head that accepts the nozzle is changeable ie: the heating part or if I need a new print head if the threads are toast.
It seemed pretty difficult to change the nozzles (hard to turn) from the beginning. The little wrench they send is a total joke.
