@Brook_Drumm Yeah I had ordered a spare tip + Ubis hotend on one of my last orders. Changed the tip and so far so good. Will the all metal extruder be an exact retrofit to the Ubis?
Just catching up on this thread. @Andre_Courchesne1 , I had some crazy struggles a while back and found swapping the hotend and new print head solved everything. I too thought I had a clog and was also using the stove to attempt to ‘torch’ the nozzle. I also was using a small needle to help clear the opening.
What I learned though is you don’t realize how much you may end up opening up the nozzle by drilling, poking, etc. When I got my replacement hotend from Brook, I’d forgot how small the opening was and how fine the filament should be.
Yeah I changed the tip last night and did a small print without any issues. Will start a new print job later and see how it goes.
I found that the filament was jamming in the hotend. If you remove the filament (likey have to remove the tensioner cause the filament will be balled up). I’d bet that it’s clogging due to heat creep up the hotend. I was already running a fan on the extruder, but for some reason something goes awry with the hotend over time. I think you’d have to put a fan on the hotend like the E3 ends have to solve. Or just get another hotend. I’m printing the awesome Halloween items from @Mark_Durbin without any issues using my replacement hotend.
