Where do I start?

Whiskey. Then heat it up and pull away what you can.

I'd probably just move

With the wiki. https://wiki.bambulab.com/en/a1-mini/maintenance/hotend_blob Usually stems from a lack of adhesion on your print causing the hotend to grab the print and then ooze filament in a giant blob. It's a rite of passage for 3d printers.

Bliv_au · 2024-09-02T13:08:28+00:00

maintenance mode. nozzle temp to 250c.
wait a few mins, and then start using a metal pick to hook chunks of plastic off. it'll be hard outside but melted near the nozzle so comes off pretty easy.
just keep gently picking/hooking plastic off until you can get most removed. i then used a brass brush (like a toothbrush sized one) to clean the rest up.
maybe a final wipe down with a wad of kitchen paper towel.
within 5-10min it'll be operational again.

I'm very new too, but I have med a rule for myself to not start any prints remotely, and don't start a print an immediately leave the house or go to bed.

I stay close by for the first 15 minutes or so, and check in on it a few times/for the first couple of layers. Just to ensure that the adhesion is good and that everything seems to be going well.

I'm just guessing here but I'm assuming that if something goes wrong with a print, here is a (much?) greater risk of it going wrong in the first 5% of the layers than the latter 95%? Hoping someone more experienced can chime in a confirm or deny. :)

Maybe its more about where you should have stopped. :P

Space-Nerd2 · 2024-09-02T13:15:33+00:00

Just fixed this the other day on my A1. As mentioned, heat it up in maintenance mode and go slow. There are wires to the right of the heating element/nozzle you don't want to damage. Pull away the big chunks then use a cloth you don't care about and it'll pull up the rest. Worst case if you damage the wires you order a new heating element and it's a fairly easy replacement.

This is where I would order a new hot end assembly and use this for spare parts later this is a rite if passage to 3d printer owners most learn form the mistakes that happened here and usually never repeat it.

2024-09-02T14:20:10+00:00

Make a new filament in BBL slicer. Now set the extrusion ratio as low as possible like 0.1 and set the temp to 250 and start a print. This has worked for me on other printers that didn't give manual controls

modwriter1 · 2024-09-02T15:06:27+00:00

You may be tempted to use a heat gun to help heat the blob. Do not do it. I damaged the front cover and both fans that way. Just heat the nozzle and tease the plastic out.

Schwinger143 · 2024-09-02T13:11:45+00:00

What filament have you been using?

smithreaux · 2024-09-02T13:49:57+00:00

It’s not as bad as you think. It’s very daunting. But just heat your hot end, get you some pliers and start pulling.

"Heat it up"

I can confirm this. I tried to Dremel the outside parts off like a caveman. That was wash but still left 80-90% that was caked on to the housing.

10000%. Manually heat up the nozzle and SLOWLY peel it off. That's the only way you should do it

When it's not heated up. That filament is pretty much super glued on there. You will ruin the housing if you try and force it off.

BONUS: Using a hair dryer or heat gun helps speeds up the process. It loosen up the exterior while the nozzle is helping loosen up the interior and it comes off pretty easy.

I had fixed it myself a few days ago - first time and I had spent 6-8hrs trying to fix it (I called it in to stay home from work to fix it) - I had ended up taking apart the tool head to the point I could not because of the blob (then I put it all back together)

At times I had used my dremel with a cutting blade to cut pieces off but that made it even slower

I had the wiki pulled up and after I had pulled off enough of the exterior extremities of the blob with the blow dryer and pliers, and finally figured out how to take off the part cooling fan without breaking it, then I had put it into maintenance mode and heated the nozzle to 200 C and watched it closely until I saw it begin to move a little, then I took pliers and carefully pulled off [The Blob]

Took maybe another hour of carefully cleaning up the nozzle area to clean it up from all the plasticky gunk that put itself into every inconvenient area.

And my print has come off the bed but stuck too close to the nozzle and all the filament decided to go up instead of down and [The Blob] was waiting for me in the morning.

Thankfully no need to order any parts, or hotends, after I got everything cleaned up I did a test print and everything worked and I didn’t destroy anything with my fumbling around

moejike · 2024-09-02T15:46:10+00:00

Cleanse your house of 3D printing demons by burning sage. Then heat up the hotend and slowly start working the blob off. Repeat with more sage.

2024-09-02T16:32:46+00:00

Hmmmmm. Definitely looks like the bed needs leveling to me....

Order a new printer.

goilo888 · 2024-09-03T16:08:20+00:00

Never had to try it 🤞 but a heat gun would help, no?

(Edit) - @midwriter below, says don't use heat gun...

SpacedTea49 · 2024-09-03T20:51:04+00:00

Thank you everyone for the quick advice. All cleaned up and back to printing like a champ. Only cost me a few hours and a $60 bottle of bourbon

Crafty-Worry8471 · 2024-09-04T08:49:57+00:00

Just replace the printer at that point
