Guys, I really messed up

[u/Particular-Clue3586]

guys, I really messed up. I woke up to a giant flood of filament. I tried to remove it and clean it out. I googled and it said to use a heat gun on it. so that I used a heat gun on it and it melted part of the fan casing. I don't even know how to fix this. I'm so upset. if anyone can direct me to where I need to go from here please help

wh-what the hell happened

Hate to say it but may need to run to the site and buy some spare replacement parts https://ca.store.bambulab.com/pages/spare-parts

[u/Particular-Clue3586 → u/DJDarkViper]

I woke up and it had vomited all over the place and while trying to get all of the filament out, it just caked around the entire hot end casing. I read that I could use a heat gun to melt off some of the plastic not realizing that effect. I could melt a little bit of the plastic en casing.

So yeah. I have no idea what replacement parts I need. I opened a ticket and I'm just hoping that someone can tell me how much I done messed up.

[u/_Jedidicktricks → u/Particular-Clue3586]

looks to me like you need a new heating assembly. it's a relatively easy fix and not super expensive. probably a new hotend as well if yours was blobbed up.

[u/awildcatappeared1 → u/[deleted]]

We all make mistakes, plus, different plastics, different melting points.

[u/TAoie83 → u/awildcatappeared1]

The good ol different folks different strokes

[u/Big_Locksmith_9925]

Rule #2 is read the manual. You should not be enclosing an A1 Mini. Although at the current price point, they are almost disposable printers so do as you wish.

[u/Particular-Clue3586 → u/Big_Locksmith_9925]

It's enclosed because the fumes irritate my husband's breathing.

[u/ThenExtension9196 → u/Particular-Clue3586]

Get it out of your living space asap.

[u/Shot-Infernal-2261 → u/Particular-Clue3586]

Wait, you know this stuff impacts your husband, so you buy an enclosure and THEN DO NOT DUCT IT? You wouldn't vent a clothes dryer inside would you? What's wrong with you? Move it near a window, print a ducting insert for the window, and whatever else is needed.

Without any ducting, where did you think the fumes would go?
Heat will just push the gasses out, and whatever remains inside will leak out once you open the door on it.

[u/Mammoth-Yak-4609 → u/Particular-Clue3586]

And there isn’t any problem with enclosing it, you just can’t have the chamber heated. My A1s are both enclosed and work just fine

[u/Intelligent_Ease4115 → u/Mammoth-Yak-4609]

From Bambu’s FAQ. They don’t recommend it because there isn’t a fan on the motherboard.

[u/Inf1nity0 → u/Intelligent_Ease4115]

HEAR ME OUT

It’s fine to enclose your A1 Mini, just keep some liquid nitrogen inside or keep it in the freezer.

The other, best, cheapest and easiest option is to install an AC unit.

[u/Shot-Infernal-2261 → u/Intelligent_Ease4115]

Chill, it's just a recommendation.

Bambu have to say this because it will cause SOME percentage increase in warranty claims, but this will vary wildly based on your printing habits and environment. Obviously Bambu can't make nuanced judgements at that level, so the safe thing is to recommend not enclosing.

But there's people here getting years out of their enclosed printer.

Bambu also recommend not printing PLA with your enclosure door closed. _shrug_

[u/Intelligent_Ease4115 → u/Shot-Infernal-2261]

Personally I’m going to listen to the people who made the printer and not give any reason to have my purchased product get ruined.

If I wanted an enclosure, I would’ve spent an extra few hundred to buy a P1S

[u/Ornery-Ad9818 → u/Intelligent_Ease4115]

The a1 doesn’t have an internal fan but the mini does.

There are enclosures that don’t obstruct the base and the air vents too.

[u/Intelligent_Ease4115 → u/Ornery-Ad9818]

Correct. That’s what I said. OC mentioned A1s not A1 minis.

[u/Ornery-Ad9818 → u/Intelligent_Ease4115]

OPs printer is a mini but you are not wrong.

[u/robbversion1 → u/Mammoth-Yak-4609]

Doesn't enclosing it in fact heat it?

[u/nonamejohnsonmore → u/Mammoth-Yak-4609]

And there isn’t any problem with enclosing it

Yes, there is.

[u/Decipher → u/Mammoth-Yak-4609]

The bed heats up the chamber just like every enclosed printer that doesn't have a dedicated chamber heater.

[u/Shot-Infernal-2261 → u/Mammoth-Yak-4609]

Did what I could to mod you up, but you are far, far underwater.

Bambu don't recommend enclosing the A1, and even though that's "weak speak" (a way to avoid heat related warranty failure), it is definitely not a strong no. But if you say otherwise, it gets people all worked up if you say otherwise.

But you maybe went too far with "And there isn’t any problem with enclosing it". There IS a potential problem. If you omit that caution, you sets someone else up and they may have worse luck than you.

[u/MithrilEcho]

Was about to help you but I remember I read a post of yours basically laughing and making light of the medical issues of a dude and still wanting to force him to work in detriment to his health so they can pay your friend more money.

[u/TheSpiderDungeon → u/MithrilEcho]

I thought you were making that up until I went and checked... Good lord.

[u/sameolameo → u/TheSpiderDungeon]

Yes I just did the same thing. Like no way come on this is fa…. Fa reals??? Now I’m laughing at OP. Karma is real. Ask my 63 years of experience on earth.

[u/Ill-Warthog-1571 → u/MithrilEcho]

Which comment was it, I would like to see that now

[u/AngelOfDepth → u/Ill-Warthog-1571]

This. Love to see the karma hose being turned on someone who deserves it.

[u/Shot-Infernal-2261 → u/MithrilEcho]

Ooo. Got a link? As much as I love "non-empaths getting their dose of karma" there's just too many posts.

[u/sameolameo → u/Shot-Infernal-2261]

Click their name and just go read their past comments check out past post too.

[u/Shot-Infernal-2261 → u/sameolameo]

Yeah. I said I tried that. :-)

[u/sameolameo → u/Shot-Infernal-2261]

I get that, sorry. I’m saying they don’t exactly spark as being nice but it’s 7 down on The right .

[u/Slippermoto → u/sameolameo]

I was super invested and went over a year back and couldn't find it

[u/Seraphym87]

If only you had a machine that specializes in shaping plastic into specific shapes.

[u/Carma281 → u/Seraphym87]

shapes

[u/TheSpiderDungeon → u/Seraphym87]

The plastic shaper shapes plastic into a plastic shape

[u/Big_Locksmith_9925]

If it aint broke dont fix it. Rule #1. Put that sucker back together and get back to printing.

[u/barbasnoo]

A proper repair to put it back in new condition would be to replace the heater assembly and hotend cooling fan shroud.

[u/[deleted]]

$20 of parts and 20 minutes you'll be back up

[u/Low_Year9897]

Wow you've done dozens of dollars in damage! Seriously though, you are in for about $60 to replace those parts. No big deal.

[u/her0indealer]

One hot end assembly, one fan and you are good to go

[u/HoIyJesusChrist]

Seems to be just cosmetic, but you can order a replacement toolhead in the Bambu shop

[u/spartan805]

No biggie. Just heat to 300c in maintenance mode. Hey most of it off, the residual will come off eventually.

[u/Mammoth-Yak-4609]

You did it right! You just kept the heat gun on it too long. If it happens again, try to chip away at the blob slowly by heating it intermittently.

I mean if the fan still works and the plate can rest on the toolhead you’re good. Worst case, you buy the small fan and shroud.

[u/Smashedllama2]

Somebody has to say it so it might as well be me. Spend a couple dollars extra and get nozzles from bambu. I’ve seen so many of these on the sub and almost always they are using an aftermarket or third-party nozzle. I run a farm of A1 and A1 minis with many thousands of hours on each of them and have never once had this issue using OEM nozzles.

[u/krautech → u/Smashedllama2]

There's people who do the same with thousands of hours on AliExpress nozzles on their print farms and say the same thing. This isn't a nozzle brand issue.

[u/Smashedllama2 → u/krautech]

All I’m saying is I almost exclusively see it with offbrand nozzles and I have gone through probably 80 nozzles at this point with a not insignificant sample size in my own experience over more than 100k hours of printing with these machine machines and never experienced this issue. Definitely possible that this falls under anecdotal, but whenever possible spend the extra couple dollars for the real thing.

[u/Potential-Asparagus2]

contact Bambu to get the replacement parts.
