Glob of filament around nozzle
Glob of filament around nozzle
New to Filament printing (started with a Form2 resin printer three yrs ago) and have only printed a few D&D tiles so far. Came in this morning and found this lovely mess of hardened filament around the printer head/nozzle of my FLSUN delta. (see attached) What in the hell happened and how do I get this stuff off now that its hard? The filament also snapped off at the real above too. Not sure if that has something to do with it. Would appreciate any help you veterans can give. Thank so much for your time and effort.

Re: Glob of filament around nozzle
We've all been there before.
Once heated, you should be able to work it off.
The easiest way to remove it is to use a heat gun (like an industrial strength hair dryer). Don't set the heat too high though as you could melt the insulation around the wires. If you don't have one, turn on the extruder heat to PLA level (~210C) and let it warm up. Once heated, you should be able to work it off.

Thank you for your helpful reply. Any idea how to prevent this or how its caused?

Re: Glob of filament around nozzle
To prevent this from happening would require getting a good first layer adhesion.
As @gruemaster mentioned we have all experienced this beginner and advanced 3D Printer users alike.
In your case you are probably lucky that the filament broke or you may have had a much larger glob of filament.
It could be possible your nozzle is too close to the bed surface and the filament is rolling up on to the nozzle.

Thank you for your help. Bed adhesion was an issue I believe form the AC in the room the printer is in was making the room temp too low causing warping of the first layers on my last print.

Could also be that the Z-Axis skipped a step or two and broke the model loose it melted around the nozzle.
I print smaller models with a skirt/brim to keep them attached to the bed.
