Fourth try on a print. Tried to add some adhesive to the bed to get it to stick better. Watched the first two layers and went to bed. Woke up to a printer on strike.

As a seethingly jealous ender 3 peasant who is still spending most of his time keeping my printer working with kludges and duct tape; it’s nice to know Bambu owners are human after all and still run into problems.
Hope you get it sorted and are back printing soon! 🖖
Haha, my ender is printing at 20mm/s to avoid slippage, with the bed scraper jammed into to filament guide to make it actually grab and feed, and at 105% extrusion, but it’s still chugging along. After a few restarts to get the fan spinning, that it.
Manged to get an ender 3V2 a few years ago, auto bed levelling is a must have feature if you intend to spend more time using your printer than calibrating or fixing it. After that masking tape fixes all adhesion problems.
I eventually turned off auto bed leveling because it just doesn’t help much. You still have to manually level the bed, and the correction it adds is kinda negligible. At least the BL Touch does help with the manual leveling process.
I must have been lucky with my Ender 3 - I only leveled it every few weeks or less. Very solid printer, had it 5 years.
I feel you - I ran an Ender 3 for 5 years but now I have an A1 and honestly don’t miss all the endless tinkering. Learned a hell of a lot in the process. No complaints about the Ender, it was a rock solid machine - now it has a new life as a laser engraver, courtesy of the Creality 1.6w laser attachment which works nice.
Your fuck up is buying an ender…lol Every problem thread in this sub is about a shit ender
👍
It’s a learning experience. Is your nozzle torqued to spec? Only time I’ve seen something like this is when the heatbreak/nozzle weren’t set correctly on a v6 hotend, and even then it just oozed down, didn’t consume the entire heatsink. I kept that in my box of learning lol, swapped everything to hotends that are secured so they don’t spin freely after that, was petg so it degraded in the heat and was such a pain in the ass to remove from set screws, was ok writing it off.
Bed adhesion is often caused by surface cleanliness in my experience, some setting will influence it but you’re going to chase problems if your surface has residual oils, some surfaces are more sensitive to it but even the oils in your fingerprints can cause a loss of adhesion. Light dish soap and water is the general recommendation for a degreaser but be aware that this will damage some surfaces, I’ve got some that explicitly want only 99% IPA and another that only wants a clean microfibre cloth.
Drafts can cause an issue too, seen some abs fail becauae I didn’t have the enclosure latched properly and the doors worked their way open with vibrations from printing, I keep mine in my garage and live in Canada, enclosures are a must for me.
OH NO
I don’t see a beginning of a print anywhere, did it not even manage to do the first layer?
If that’s the case, a word of advice to always be present for the first 2 layers of your prints, at least for the longer ones.
I didn’t take the photo immediately - tried cleaning a bit before it occurred to me to document it.
I had that happen once. it just bout pushed the fan off the head since the clips are broken but it fits good enough™️
I’ve been doing 3D printing regularly for a decade or so now… Never had a blob.
I’ve been printing for two weeks, and I had one.
Apparently the A1 mini is supposed to have a mode to detect this a You just have to enable it.
I don’t think it’s supposed to do that
I’ve run into adhesion problems when the room gets colder.
works 99% of the time, but when ambient temp goes below 70°F everything starts failing.
Interesting. All of my prints that failed were running overnight when the temperature dropped.
Yeah, in some parts of the world, a box surrounding the printer isn’t really a luxury.
Haven’t had problems since I upgraded.
Controlling temperature is important on FDM.
that looks like delicious taffy. like an abba zaba
Nozzle not seated properly?
or no nozzle?
I’ve a massive blob like this one time when the nozzle got clogged and the extruder created enough pressure to push the filament through the threads of the hotend block. It was on an Anet A8 and I ripped a lead off the thermistor trying to get the plastic off so I ended up replacing the entire hotend.
You can try to heat up the hotend to a fair bit under the melting point of the filament to where it’s soft and somewhat pliable but not runny or sticky and then trying to peel it off. Though you’d risk damaging any leads to the thermistor, heater, or your hands if you’re not careful.
Good luck on fixing the printer and getting back to printing again. 3D printing is a really time consuming hobby
Thanks. I am really frustrated with myself for letting this happen. Pulled everything apart and recovered most of everything, but managed to damage the clip that holds the extruder in place, so now I get to learn how to do surgery and replace the entire assembly. I wish I had gotten a bit more time before having to do a major repair…
Hey, ummm… I think I see the problem. Your printer has diarrhea

Atleast it didnt get wedged in the heat sink… Thats what happeneed to my last blob, had to replace the entire hot end.
Aren’t these closed hardware? good luck finding replacements parts
looks at all the replacement parts that came with both my Bambu printers and the extra nozzles I ordered at the same time
What are you even talking about?
Did they include a new hotend or can you get one? I look on their site and see nothing for that.
Edit: I looked under Spare Parts and they weren’t there, but I see them under Accessories. And for $13, I’d sure as hell buy one when I got the printer. Along with a bunch of other parts, they’re quite reasonably priced.
You get a spare hotend with the purchase of a P1S so I assume they give you one with any of their printers.
You do on the P1S? I’m highly tempted to get one with the AMS, I have several printers that I’ve bought or built over the last 15 years, but even the ones I’ve bought need to be fucked with every time I go to print. The word I’ve gotten is that these are pretty much ignorable and ready to go even after a long hiatus. And an enclosed build chamber for potentially using ABS again is very interesting to me. I stopped fighting with ABS when PETG came out, but it has it’s own set of shortcomings.
That’s my exact setup and it’s great. I wouldn’t trade it for any other printer. It being enclosed is fantastic.
It very much is a printer you don’t need to pay attention to. Works as it should out of the box. Only thing you need to do is some maintenance. Cleaning, greasing some rods, etc… It doesn’t tell you when to do it like the X1C (from what I’ve heard) but greasing rods is like an every 3 months thing. All their maintenance on what and when to do it is on the Bambu website.
As it’s my first printer I’m not aware of any issues after a long hiatus. All I can say is that I often don’t print for a month or 2 and it prints just fine when I get back to it.
I’ve only ever had issues with the AMS where it would snap the filament but that has only ever happened when my filament was almost empty and thus very light. I should’ve either weighed it down or welded the leftover on another roll. Plus that doesn’t happen if you’re running out mid print. Only ever happened when I initiated a new print with the almost-empty roll.
It might not be cheap (or maybe it is, I dunno) but replacement parts are available. https://eu.store.bambulab.com/en-se/collections/spare-parts-for-a1-series
There is also a chance that they can rescue it without replacing anything, but it will very likely be quite time consuming and they will have to be careful to not damage anything.
This also doesn’t look too bad.
These nozzles are cheap. And it shouldn’t be very difficult fix this one if you have a heat gun. The hard part will be to get at the latch that holds the the nozzle assembly in the extruder. That’s small, fiddly, and delicate part that there is a good chance of breaking.
So while you are ordering that spare heater assembly, ($20US) you might as well get a new nozzle too, ($10US).
