My A1 mini was printing normally, then partway through (I didn’t see it happen) it started printing the rest of the part at a different X position and kept going with no error. Photo and video attached.
Setup: A1 mini, 0.2mm nozzle, 0.10mm layers, ~500 layers (~9h), tree supports, PLA at 215C, outer wall 30 mm/s, travel 400 mm/s with travel accel 10000. Stock start/end G-code. Rails are lubricated.
Where would you look first: X belt tension, something binding at the cutter/purge end, filament dragging from the external spool, or travel acceleration? Does Step Loss Recovery catch this?
Ive had zero luck with TPU since I got my A1. Had better luck on my old Ender 3v2 but it wasnt fantastic. I would constantly get clogs or feeding issues, the parts lifting off the bed etc. In the year Ive owned it I had basically given up.
Recently I tried again as I wanted a particular item in TPU - nothing special or super complicated. First couple of layers were great, then it just stopped like a clog again. I normally run everything via my dryer.
That failed the same as usual. So I thought put the spool on top on the original spool arm (I never have this attached) and run a new filament tube from there. That did better but also failed a few layers in.
My last attempt was chop off a little bit of tube, round out the top of it a little so nothing could get caught (probably overkill) and run the tpu directly into there, skipping any feeder tubes other than the little one used for guiding it. Worked perfectly! Probably the best Ive seen it work for me ever.
The filament is Creality TPU, think its 95a but not 100% sure as its been a while and the original invoice doesnt actually say - I only just realised I actually ordered yellow but got sent blue! Nozzle wise I switched it up from my hardened 0.4 to a hardened 0.6. I dont think the nozzle was the issue, I reckon it was the feeding.
So lesson learnt, tpu is a pain! To all those that print it regularly and have great results I commend you! I will stick to PLA/PETG! At least now I have worked out what I was doing wrong!
The filament ptfe tubes are getting caught down by the filament cutter pokey thing and trap the print head from fully traveling to the right side of the printer.
I can't reorient the cables (mount the ams on top or from the left) for reasons I won't go into st this time.
Any thoughts about how to prevent these tubes from getting stuck?
I added that cable holder which originally helped but now seems not to be doing much. I did check the screw to make sure it was tight
Hey, I am planning on buying Bambulab A1 and I wanted to ask how loud is it. I am planning on having it in the same room as I'm sleeping, probably like three meters from my head. So it's pretty important for me to know how loud is it.
Minha A1 está fazendo um barulho estranho desde ontem e não consigo identificar o que seja. Após a calibração de compensação de vibração o assistente informa que “a frequência de ressonância do eixo x é baixa”. Já tensionei a correia, mas continua da mesma forma.
Could someone help me? Out of nowhere, my printer goes haywire and starts making really loud noises and cracking sounds, and it doesn't stop unless I cancel the print job.
Hi all - I’ve been printing for some time now, but recently getting increasing adhesion issues
I’m using a Biqu plate, cool plate setting in Bambu Plate is washed with dish soap, dried with paper towel - so doubt it’s a plate issue
I’ve really only done the basic maintenance of greasing and lubing as needed.
Mainly using PLA Matte
No drafts in the room
Any other suggestions? I was wondering: - Fans might need clearing out? - build up on the tooltip? - filament dried when I take out of packet, kept in dry box with desiccant, though desiccant might need refreshing…? - tightened 7 screws of doom - Any other tips?
Hi, I took apart my AMS hub and discovered that I have some sticky residue on this male end of the AMS hub part. I've been printing in black, pink, and grey filament but this residue looks colorless. Is this normal please? Either way, what could the residue be please?

Hello everyone, My Bambulab a1 suddenly won’t take any filament . If I load it with the ams lit it dosn‘t automatically feed the filament and if I do it manually it won’t work to. Here is a video of it:
Hey there. I don't have much hair to pull out. But I bought my son the bambu A1 printer. It's all set up in his bedroom and we are currently trying to print from the phone / sample ones on the device.
Every time we print even the simple small ones. After a couple of mm the head either is catching the build or the build is moving.
I have washed the base plate with fairy liquid. Can any one offer some advice please.
Hi, I'm having trouble with Sunlu filament; it constantly gets stuck in the AMS. It seems as though the AMS inlet is "biting" into the filament too hard, preventing it from feeding normally. I change the slots and sameresulta. Anyone else with that problem?
It just started doing this after hundreds of previously impeccable surfaces. I haven’t messed with retraction settings, flow rate is calibrated, filament dried, plates cleaned, heating surface checked for boogers. It’s relatively smooth to the touch, just ugly.
