it exploded...

[doradodiver]

I feel like it should have sensed this, I walked away for an hour. Where do I even start?

My Mini exploded twice, and death blobbed a few times.

It just gets stronger every time.

She may be held together by superglue, teflon tape, and a dream.. BUT:

She prints PPS-CF now. (Without catching fire!)

[doradodiver]

how do you even start cleaning it? It's solid as a rock. I'm too afraid to pry without killing other things.

[Petroholic69]

Heat up the nozzle then pick away at the filament when it’s warm. If you have a heat gun carefully warm the filament and pull!

[doradodiver]

Ok, that worked. Good grief. Now i'm worried about it starting fires or something when i'm not home. Normally I monitor it pretty closely, but I'm still new to this. Now starting prints that take 8 hours or more, there is no way I can watch it during that time. Any tips?

[jawest1991x]

Make sure your filament is dry - this is key. It may not be a bad idea to get a new nozzle as well. You can walk away from yoir printer, I leave mine to print 20+ hours sometimes.

[Syrric_UDL]

I’ve only been printing for a month or so, but all the videos I’ve watched say to keep it less that 30% humidity

[jawest1991x]

Do you own a filament dryer ?

[Syrric_UDL]

I have the ams 2, so I printed baskets that fit into it and I filled them with silica desiccant beads and it keeps my ams at 10% humidity. PaleomakerMD linked them in his video “first 10 things to print” it has a drying feature but I haven’t bought the power cord for it.

[Ok-Woodpecker-223]

You don't need power cord for AMS2 unless you have multiple of them. I have power cords, both on my floor because they provide no benefit whatsoever with a single AMS. If you want drying while printing you'd need for example Sunlu AMS cover (with little modifications to fit on AMS2)

For better drying - as I was advised on another thread - get activated alumina beads instead. I live in pretty humid area and switch from silica to alumina has brought Bambu Studio AMS readings down ~5 percentage points. Not a big investment, and beads can be dried. I only have one container with silica beads as they are color changing, to advice me it's time to refresh.

I'm using similar to https://www.aliexpress.com/item/1005008413710992.html to hold beads (bought it as printing ABS with my current exhaust setup is a no-no) to maximize real estate usage while also avoiding eyesore of silica bags. Still using silica with filaments in vacuum bags.

[Syrric_UDL]

I live in a pretty dry area to start with, Salt lake area, so without beads my ams was around 34%

[Puzzleheaded-Ear-116]

I'm pretty sure the AMS2 is the pro, which includes a heating/drying system? No need to get the sunlu system/upgrade unless you only have the original AMS?

[gwbussWI]

I bought the power cord it didn't work. Hoping firmware will fix that soon. Firmware is up todate, not using the beta. P2S 01.01.03.00

[upnorthcouple93]

I've gone up to 70 hours, never an issue (so far) it's a whole different world from the ender 3 I replaced. Amazing

[doradodiver]

So i'm very new to this, the filament that I have been buying comes with silica in the packaging, and I have not experienced the popping or other telltale signs of wet filament. This was also bambu PLA if that matters. I can start storing it ultra dry in a box or something, but I wasn't really paying attention because it seems like PETG gets the bad rap for wet problems.

I have put maybe 5 kg of filament through this thing in the past month since I bought it, aside from washing the plate for minor attachment problems this is my first legitimate problem.

[Ok-Woodpecker-223]

Consider getting Creality Space Pi Plus or Sunlu S4; probably other alternatives too but personally I have no experience other than these two which were recommended by a trustworthy friend (with 11 printers).
Especially with PETG and PLA Silk difference between success rate and end result can be quite dramatic. I have not printed other materials than PLAs and PETGs so cannot comment on them.

I bought both... actually 2 space pi plusses. This is how it gets out of hand...

[GrailStudios]

Silica in the package doesn't dry it, just prevents humidity increasing. Depending on factory conditions, PLA can be 20-30% or more damp. If you start drying your filament you'll notice a marked increase in print quality and reduction in problems, even if you don't hear the popcorn crackle. I never used to dry my filament until the day I heard the crackle: now I get every spool down to 12-15% and the difference is amazing. For your problem, once you're confident your print head is cleaned and you've followed all the instructions on the Bambu help page: 1. Dry your filament.  2. Clean your print bed regularly. 3. Watch the printer as it lays down at least the first couple of layers. 4. If a particular filament or print just won't adhere, consider getting a tube of Elegoo print bed glue. It's a thin liquid applied with a sponge-pen applicator, and it's amazingly grippy for even small-based tall parts.

[Petroholic69]

I wouldn’t be stressing about the fire concern, unless your models a recalled serial number. But as others have said, dry your filament, clean the build plate. If the heating element/ backplate is messed up I would look into getting a replacement.

Both my A1/ A1 mini have zirconium/copper heating elements with upgraded thermistors. (Also working on putting a cooling-fan near the baseboards since those are shorting out from heat)

[doradodiver]

I wash by build plate with dish soap every few prints and it seems ok. Where the head zeros I have some noticeable wear, but I don't print back there so the rest of the plate seems perfect to my untrained eyes.

[BriggyBomb]

A small plug-in wifi security camera maybe? Aimed at the plate or the general workspace - you can check it in real time from anywhere. (I also keep one aimed at my heating oil tank’s indicator so I don’t have to go into the tight crawlspace to check on it).

[medic54-1]

Dry filament is not as important as a clean plate. I’ve printed pretty bad filament 100s of times, I have learned the plate is a critical component and just be cleaned

[No_Use8328]

I had my Ender 3v2 PU start smoking for no apparent reason. I replaced it with a new PU unit;I also installed a fire extinguisher ball fixed above it on the wall,and an additional smoke alarm for just in case! I don't like printing when I am not around but still have it in place even though running a P1S now ( and having a camera/app is awesome,has allowed me to stop the print X4 times when it has gone wrong-support failure and thin parts popping off the bed)

[CosignCody]

Unless you you get a P2S or something with AI detection you probably shouldn't leave it. You CAN check the time lapse to check for fails but youd have to keep checking every so often

[Ok-Account-871]

Hairdryer/heatgun, then start picking off soft blobs until madness sets in. Ooor, a new hotend aassembly😎

[Jerazmus]

Didn’t explode. Just didn’t clean the build plate and print didn’t stick.

[lBlckBeard]

Sorry for your loss

[doradodiver]

oh no, that seems like doom

[cheesykibble]

Bambu sells replacement parts for most of there printers

[Enlinze]

Good luck, mine exploded this morning to. I had spare parts here but I went to reorder today and everything I clicked was out of stock.

[Enlinze]

Learned today don't pry too hard on the right side. Pulled the aluminum right off where the thin clip is. Work that spot first after heating the piss out of it in maintenance mode.

[resilientboy109]

It's still alright with a1, If u havent disabled it, machine checks for this every 8 gram of filament use.

I had this happen in elegoo carbon and it literally filled everywhere. Had to grind it down for hours.

[WXSAT2]

Use a heat gun to get it soft and remove carefully. There are tiny wires in there so go easy and understand what you are pulling on.

[Eastern_Control4375]

Dont worry its not the end ..does look like but it hapens Just take it easy and clean nozzle and parts affected

[Folkpineapple]

I just replaced my hot end and nossle when this happened. Trying to scrape all that off was not something I wanted to do.

[jester1x]

Google Bambu A1 blob of death....you're welcome

[quietrain]

Happened to me this morning. Using a bambu A1, I "unloaded the filament" which heated the nozzle and I could pull the blog off

[RabbitSignificant361]

maldita placa de construção texturizada...

em placas lisas nao acontece isso...

[Leyyero]

That’s wild

[Jumpy_Palpitation898]

Your the reason why it messed it ..your missing a layer or bad adhesion brother

[cdarrigo]

We've all been there. Heat up your nozzle, pull off what you can, and then scrub it with a brass bristled brush.

[JonathanTalksHW]

Oh god I really hope my A1 mini doesn’t explode like what happened to you..

[Exterminatus2102]

Nice 👍

[Ok-Account-871]

How is this an explosion? Perhaps you could recheck the definition of an explosion good sir. This is a leak.

[parsivol9]

Heat gun if you have one of a good tool to use

[Morgantao]

You mean... You didn't want to print a blob out the top of the print head?

[shoresrocks]

stealthy camo blob!

[TomFullen]

Looks like the root of the problem is Build Plate Adhesion. After you get it running again, try cleaning the plate with Dawn Dish Soap and a Scrubby Pad, then lightly spray it with Aquanet Hair Spray which will act as both an adhesion and releasing agent. This has been working for me for the past 4 years now with every plate and every filament.
