A1 Mini extrusion issues after blob of death - now damaged a brand new build plate
Has anyone experienced something similar with their A1 Mini?
I’ve only had my A1 Mini for a few months and, up until recently, it was absolutely fantastic. Print quality was great and I had very few issues.
A little while ago I had a blob of death form around the hotend/nozzle. I carefully cleaned everything up and after that I actually managed to get several successful prints, so I thought I’d gotten away with it.
Since then though, the printer has become very inconsistent. Some prints work, some don’t, and now I’m having an issue where the printer starts a print but little or no filament is actually being extruded.
The worst part is that the printer just carries on printing as if everything is normal. Because no filament is being laid down in some areas, the nozzle ends up dragging across the build plate and has scratched/melted away part of the surface pattern on a build plate that was literally brand new.
In the video I’ve attached, you can see the filament not extruding properly while the print continues. You can also hear a clicking noise in the background whenever this happens, which sounds like it’s coming from the extruder trying to push filament through.
Before the blob of death, this printer was rock solid. Now I’m wondering if the blob damaged something in the hotend, nozzle, extruder, or filament path that’s causing these extrusion issues.
Has anyone had similar symptoms after a blob incident? If so, what ended up being the cause?
I’ve opened a support ticket with Bambu, but I’d be interested to hear if anyone in the community has dealt with this before.
