Hi, I’ve got a stubborn clog on my Finder - have already checked no jam in the feeder mechanism and can push a cleaning needle up about 2 inches into the nozzle. Pushing down from the top of the extruder isn’t helping so I suspect there is a clog near the top of the heating element. I’m thus looking at removing the nozzle and PTFE tube, but it’s on pretty tight so I think a socket wrench is my best option to loosen it. However, the closest socket head I have is a SAE 3/8th inch head but it is SLIGHTLY too big. I suspect the nozzle needs a metric socket head, but my current set only goes down to 9mm which is too big. Does anyone know what the bolt size of the Finder nozzle is so I can buy just the socket head I require?
Thanks!
I was thinking 9mm but maybe it is 7mm. Did you remove the stepper and drive assembly?
It is not uncommon for the filament to get a blob at the top of the cold tube right under the drive assembly.
Thanks - yes have removed the stepper motor - I can just about see the block but it’s about 1/2 a centimetre down into the cold tube which is too far to grab even with fine tweezers, and trying to push it down isn’t working. I’m hoping if I remove the nozzle then it is either stuck at the top of the PTFE lining or I can otherwise poke something sturdy up through the bottom of the extruder so it comes out the top.
Probably the right plan. Make sure to heat to about 220-230 or so before removing the nozzle.
Same for re-installation. Snug the nozzle while cool, heat and snug again.
Google for instructions also. Brass nozzles will snap of fairly easily.
