Hi guys,
Many of us are facing clogging problems ( often or not so often ) especialy when prints with flexible filaments and try to figure out what in the world is going on. An E3D V6 or so hot end is a very clever as well as simple design to spread the melted filament onto heated bed. During the high temerature - from 200 deg Celcius and over- for long periods ( over a month and a half - if you print almost 24/7 ) , clogging appears and the prints are only in fairy tales. What is happening here? Some of you guys i'm sure you know it, but others don't, so here i'm to show the solution:
Right before the nose and the heating block, there is a smal diameter PTFE tube ( 3,2mm Φ if i'm correct ) that guides the filament right into the nose feeded from the feeder Alu body. ( sorry for my english, but i'm trying to help
).
The side of the PTFE tube that " touches" the hot nose, tends to burn and shrink and this cause the filament clogging. See attached picture.
This tube nedd to be changed every one to two months. It's cheap and 1 meter lasts at least one year.
If something seems unclear to understand, please tell me!
Cheers
