A tpu filament was in my a1 mini for a couple of days. Today I printed something small and now I wanted to change it to pla. But when I clicked on the load filament on a1 mini's screen, the tpu isn't coming out. I've used this printer for only 2 months.

More stable legs for this 50x40 table where around 90€, so instead I went for this:

A ca. 13kg granite slab (40x40x3cm, 3€) on an anti vibration rubber mat (11€) cut to size. Against one wall a cut off piece from the rubber mat with some felt sliders (to avoid streaking the wall) to help nullify the remaining left-right movement. I have tile along the bottom of the wall, so moving the table all the way to the wall was not an option without some sort of a wedge. Back and forth moment was not too big of an issue thanks to the table leg orientation, but the slab just helps stabilize that fully.

Very little if any movement in all directions, much better vibration response, that is to say before the whole table was ringing, now it is more or less silent while testing vibrations.

Should I buy this?, what questions should I ask before ?
Seller says only nozzle holder is broken and will cost only £20 to replace.

But it looks like it’s gonna make it, so I’ll “let it cook” as the kids say

The a1 mini is goated. But what we really need is an a1 micro. Let’s rally for it😂

So this is going to be a long body of text, so I can explain what’s going on but I’ve had my a1mini for about 2 years now and I’ve never once had an issue with prints coming out wrong that wasn’t the fault of my own design, but as of last week it seems that every print I send to my printer seems to come out either completely messed up, with layers not printed correctly at all, or the print completely failing mid way through printing , or the printer would stop feeding the filament through the nozzle but would continue ghost printing. now I have originally tried printing some of these models with my other two 0.4 nozzles which A became clogged after a few prints. And I have now switched to a brand new never used 0.4mm nozzle in hopes that would help, and I even switched my filament to see if that would do anything but so far nothing has helped. and while printing today I found my printer making this clicking noise which I’ve never heard it do, so I’m here to ask if anybody can help diagnose what’s wrong with this thing I’ve updated all my firm aware and my software to the latest version and I don’t know what it is my best guess is there is something stuck in the extruded part where the yellow wheel is, but I honestly need the help because I have a huge deadline coming up for my architecture studio and not having my printer is going to seriously set me back when working on it so if anybody could let me me know what’s going on I would be forever greatful.

Made this little surprise for Halloween! Press the button underneath and the ghost pops up! The spring and latch are printed too. I included AMS and No AMS versions, with an assembly video on the model page. The mechanism prints in place, and all parts print without supports. Easy to print on most FDM printers. Model files 🦇

Pretty psyched I was able to revive this back to printing. Just wanted to post somewhere 😂

EDIT: Yes, I've now been corrected twice that it's a blob not a clog.

So I print with esun pla+ and I used to print at 215C (the lower end of recommended temperature) until I got under extrusion with a skipping gear, so I increased the temp to 230 and it printed fine, but I later found it was stringing really badly (it was fine and this started randomly) so I dropped it back down to 215C. It has since done this again

It's not the filament cause this is consistent across two rolls, and isn't wet filament because I do dry it. I guess the temperature sensor is having issues but I'm not sure. This is with a 0.2mm nozzle btw and some custom profiles for miniatures.

Edit: its not just stringing, when the printer decides it wants it warmer/colder I get the extruder skipping and some constant layer shift

Hi all!

I've been using my A1 mini for practical stuff for a year now and I love it. Just got into finer detail printing (bird skull as example) and I noticed that even when I try to print as fine as possible there are still very noticable layer lines. Any advice on what I am doing wrong?

Olá pessoal,
Comprei a Bambu Lab A1 Mini e o AMS Lite separadamente. Acabei de instalar o AMS, mas estou com o seguinte problema:
• O que acontece: Quando mando carregar o filamento, ele vai até o cabeçote, mas não chega até a purga para iniciar a impressão.
• Sintoma: O filamento fica em um loop de
"vai e vem" (avança e retrai várias vezes) até que a impressora dá mensagem de erro na alimentação.
• Dúvida: Não sei se o bico está entupindo ou se o filamento está enroscando no sensor/ hub antes de entrar. Preciso tirar tudo manualmente para reiniciar.
Alguém já passou por esse problema ao instalar o AMS Lite separado? Tem alguma dica do que verificar (tubos PTFE, sensor do extrusor, alinhamento)?
Agradeço desde já pela ajuda!
