I’m new to 3d printing, got an A1 mini just to test the waters before diving into something more advanced. It has been really easy to use and an amazingly engineered machine.
Only things I encountered so far has been fillament falling off of the spool and getting tangled at the start, which I think I have found out a fix using an adaptor and AMS rotary spool holder. But the second issue I can’t figure out:
A bit of filament is hanging from the nozzle when a print ends, and on sending the next print the head taps on the plate and sometimes drops it on there and sticks to the print later, other times I have seen it coming off and blown away to random locations, etc.
Here’s a photo of the nozzle and the filament piece after the print is done.
I think if I can make it poop and shoot once right at the end that comes off, but I don’t know how to set that up, or does anyone know a better solution?
I noticed the same , but next print will clean it itself.

That’s normal, it will clean itself off when it starts the next print.

That happens because your filament needs to be dried. The post-print dribbling is mostly just an annoyance. Before you start your next print, just grab it and snap it off.
But it’s an indication of another issue (filament has absorbed moisture from the air) that is probably reducing the quality of your prints. It’s noticeable when the printing ends as the nozzle cools off, but it’s happening all the time during the print, too. Whenever the printer stops extruding to move the nozzle someplace else, a little filament is oozing out. And the mechanism that causes the oozing (water vapor heats and expands) also causes some slight over-extrusion.
So if you get and use a filament dryer, this issue will go away and your prints will probably look better.

Thanks everyone for the help.
It seems to try to clean it off next print but then goes and taps the plate with that bit already hanging, where it sometimes come off there.
I can pull it off when I pick up the printed piece though no problem.
@RocketSled I printed a benchy it came out perfect, I have a filament dryer though that I bought for PETG which I haven’t unboxed yet, I will put this PLA in that to see how it goes.
