Blocked Nozzle??

John — Fri, 27 Dec 2024 16:12:08 +0000

Hi There, I cannot load a new filament as there is a blockage. It'd not the nozzle as I can push the needel in a fair way so it's somethin further up the tube. Not sure how to approach this problem but wonder if I need to drop the whole of the hot assembly out to see where the blockage is?

Thanks,

John

MK3s and some mods, wont print, minimal extrusion...see text

Well, new to this, got a MK3s, bear upgrade, bondtech extruder and a slice copperhead tip on it, trying to get this to work, bought from some guy who was moving, pretty good deal...anyways, firmware 3.11,0-5475, seems to not be squirting out the media. changed tip out with one in a baggie included with the stuff.... cant get any volume. Passes calibrations, loads/unloads fine, goes through the motions with calibration print pattern with very little stuff coming out, just trickling out and curling up. I've been reading up on this for a week now. ready to sell it...lol.... actually want to get it to work. I have zero programming experience so this may be out of my wheelhouse. Any ideas folks? I appreciate all the help I can get.
