E3D nozzle sock
I bought an E3D nozzle sock pro pack along with a new heater block and nozzle. I though that the sock would keep plastic off the heater block but after about 1 hour of failed prints I removed the sock and found at least 3mm of plastic over the entire heater block. Has anyone else used the socks.
Re: E3D nozzle sock
I use the 3M Scotch 70 self amalgamating silicon tape which NopHead promoted for the Mendel90. I don't like the pre-made sock idea for the very reason you are posting. It looks as if it is a slack fit and unless the area round the nozzle is trimmed back there is a high probability it will block and divert the filament flow.
I do not cover any part of the nozzle with tape.

Re: E3D nozzle sock
I have noticed that any stray blobs would attach to the sock then release later in the print causing the nozzle to break tall prints off the bed. The buildup between the sock and the heater block was awful and probably a reason for my terrible layer adhesion. I have been having extrusion problems and replaced the nozzle and heater block to try and resolve but the sock set me back 10$ and 3 days of confusion.
Re: E3D nozzle sock
No idea where all your socks may come from.
Using a good sillicone sock as lots of others do there should be no problem at all.
I have been using mine ever since I got my MK2S nearly a year ago.
This one I made myself with true high-temp sillicone ( https://www.thingiverse.com/make:384804 )
and there is no chance that anything will stick to that sock.
Having molten filament acumulating between heat block and sock
there most certainly the hotend is incorrect assembled.
Probably the nozzle tightened against the block but not the heatbreak
which could lead to leaks.
A fitting sock in any case could not be the reason for inconsistent extrusion or even clogs.
Quite the contrary, it keeps the temperature stable in whatever environments and fan speeds.
Re: E3D nozzle sock
Thanks. It seemed odd that I was having those problems. For one, E3D puts a lot of time in the stuff they make. I will disassemble the hotend again and make sure everything is correct and give it another try.
