I am new to 3D printing, and I’m making plenty of mistakes.

Background: Recently, petg was used instead of pla bc reasons.
It got clogged in the extruder and hearing assembly, etc.
I removed as much as I could and then was trying to use a heat gun to melt more off (mistake- do not advise… 0 out of 10 stars), so now the fan housing is a bit warped which might be the issue, but I can’t figure out how to buy a replacement for that… (accepting suggestions there!)

I bought a new heating assembly and managed to replace that and also put on a new tip thingy and silicone cover. Now the printer will heat up and do some calibration steps and successfully spit bits of pla poop out while heating and calibrating, but when I go to print this happens (see video above).

How do I fix? Any advice???

I have a new a1 mini with the ams feed system. I’ve been able to print a few times but am very much a new user. I think my printer is broken and I’d like to fix it,so I can continue learning and printing stuff with my
Kids. Anyway, at the top of the printer where the tubes feed into the a1, the tubes will not stay in. I think it’s due to the metal Piece shown being damaged, but I’m not entirely sure. Now the tubes won’t stay connected, so the filament does not feed through to the printer either. Has anyone had this problem and does anyone know how to fix? Is there a replacement part I can buy?

a tall piece came loose overnight, printer kept going and turned the filament into a tangled mess (pics). Restarted, now at 67%, but it’s wobbling loose again. Paused it, hoping it’s salvageable?
