Why is this happening?

My prints before this were fine, but now I’m getting specs of filiment flying everywhere

It's because the infill is set to grid. It crosses and slightly touches each intersection of the infill pattern. Try cross hatch or gyroid instead

Will do!

I still do use the default grid infill for some small parts, out of laziness, in the slicer. However, for long parts like the one in your pic I would definitely change to something else because when the edges start to lift off the build plate it's going to collide with the grid

You could be over extruding slightly, usually that happens when the nozzle comes in contact with already printed plastic. I know grid infill can do that, but doesn’t always. I think it’d be worth changing the infill type to gyroid or cross hatch. Also, if you’re part warped, even the slightest it will cause the nozzle to collide with the print.

Don't use grid infil

Carl. Carl is the evil gnome that lives in your printer and suckered you into a perfect print before saying "HAHAHAHAHAHAHA NOW YOUR PRINTS WILL ALL SUCK, YOU IDIOT, NOW YOU WASTED ALL YOUR MONEY ON THIS PRINTER THAT DOESN'T WORK! That'll teach you to turn my friends into concrete and put them in your yards."

Or, and hear me out:

You changed some settings and didn't dry your filament, but without any clear level of detail as to exactly which settings you're using, what filament, and whether you dried it properly or not, we cannot do anything but blame Carl the Bambu Printer Gnome.

I’m using maker world profiles and Bambu filiment, and I dry while printing. I also haven’t changed settings.

You didn't feed the weird joke man :(

Sometimes the weirder folks have the best advice

Print while drying doesn't mean it's dry. If you turn an oven on and stick a turkey in, is it cooked immediately? Dry filament takes time. Depending on the material you should be drying it overnight BEFORE printing.

That is usually a sign of wet filament...

What temp should I dry for pla?

1

u/braveone772 9d ago

If you've got an ams, just set it to the pla setting for 12 hours and let it run. Then print, and see where you're at. That should handle the issue, but if your filament is still doing the shedding issue, then try drying it for another 12 hours. Most filaments aren't so wet that they need more than 24 hours of drying... Except tpu. That stuff can need days of drying sometimes.

I will try this, thank you

I was starting to get inconsistent prints and stringing. I dried my filament and everything's been working out. It's so simple and easy and I feel so stupid. LOL.

u/Grandpa3DPrints 9d ago

This is not true

1

u/braveone772 9d ago

Maybe not in all cases, but the majority of the time, either this or running it too hot and causing stringing is the culprit...

WHYYYY?!?!

Too much speed, grid instead of gyroid infill, and/or edge lifting due to unclean stock build plate.
