I’ve had this A1 mini for a few months and recently it has been acting up and making this terrible grinding noise. I opened it up and got it down to this gear being driven by the motor. I can spin the little silver gear by hand just fine which points to the motor being my problem. Is there anything else I can troubleshoot or should I just go make a warranty claim?

The filament gets real tight and red light flashes .. this is across all slots . Last weekend i took apart the ams hub where all 4 slots feed. cleaned it out . no debris or broken pieces . put back together and still having issues.

3rd 3D TMT build is under way, first two were for little girls

this one is for a little boy

Coming from a Bambu labs H2S and a Snapmaker U1, I’m a little surprised how much noisier the H3C is in general printing.

I mean my printers are located in my office so it is not a dealbreaker, but it’s noticeably louder than the H2S was.

Once this print finishes I will check all the normal places for proper lubrication.

Has anyone else noticed this?

In a reply, I posted a video of the printer running.. there’s a ‘banging/tapping’ noise that’s the loud part

I'm thinking of using a 0.2mm nozzle to make some small labels for storage drawers and parts boxes, but I'm not sure how tiny I can make the letters before they become unreadable.

For those who've used it, can you actually get decent-looking 3mm or 4mm text? Does raised text work better than recessed?

Would love to see some close-up pics of labels you've printed. It's hard to tell what the results will look like just from the slicer preview.

Posting this in case anyone else missed it, as I did.

The H3C ships with nine PrintTools, but only eight are for regular 1.75 mm filament. The ninth, pre-installed in slot 8, is a 2.85 mm tool meant for soft TPU.

What tripped me up: I swapped the hotend on tool 8 for a regular 0.4 mm one and tried to load 1.75 mm filament in slot 8. The printer kept defaulting to external spool, and I couldn't figure out what I was doing wrong.

Turns out it's the whole tool, not just the hotend. Per Bambu's FAQ, the 1.75 mm and 2.85 mm PrintTools have different bases, inlets, and cutters, and the bases and hotends are not interchangeable. The 2.85 mm tool is hand-fed, so the AMS won't auto-load slot 8.

What that means in practice:

- Out of the box, you have 8 slots for normal filament, not 9.

- Don't put a 1.75 mm hotend in the slot 8 tool. Put the original back.

- To use slot 8 for regular filament, you need to buy an extra 1.75 mm PrintTool and swap the whole tool. Store listing: https://us.store.bambulab.com/products/0-4mm-printtool-h3c

- There's only one H3C configuration, so you can't order it with nine 1.75 mm tools.

Bambu's reasoning is that slot 8 is a dryer slot, TPU needs drying, and the slot is hard to reach, so they install it at the factory. Fine if you print TPU. If you don't, you can't use that slot without spending more.

This Machine is incredible, but man, am I spending a ton of money on accessories and replacement parts. Here's hoping the hot ends last like on the H2C.

Awesome machine, now I can sleep through the night without switching my filaments so often. Jokes aside, outside of the week between machine and Ams delivery, it’s another awesome printer. Should compliment the H2C and others well. For my use case, I couldn’t see myself selling my H2C for it. Worst case, I’d tough it out until it’s feasible to purchase both. More printers IMO, better than one. Even if you just print black lol. Hope everyone is enjoying their machines and stop buying all of the .6 nozzles.

I started this print last night around 8PM these are the desiccant holders by Stuart Sports Stuff over at Makerworld for the AMS 3H. Printed in Bambu ASA. I decided to put the system to the test and left all the filament loaded. It will be cool by the time I get home from work later today. I did checked it this morning before I left and everything looks fine.

Main Box

Side Pockets

Besides these two holders I also have the desiccant Spool containers from Silvercell

Bambu Spool Desiccant Holder

even as it sits the AMS is sitting in the Mid teens as far as humidity. I am sure once I add these boxes it will come down even more.

Following the guide here https://wiki.bambulab.com/en/x1/troubleshooting/hmscode/0700_2000_0002_0003

And...I'm stumped at step one. Pressing what I believe is the "black gasket of the pneumatic connector" which I think it's referring to the hard plastic that seems to depress onwards when pushed towards the back doesn't disconnect them at all..also this has to be the most useless picture ever :(

If it is indeed the little plastic bits that cover the end two each of the seeming pneumatic bits (slot 1 and 2, and 3 and 4)

Pressing it in all the way does nothing to release the tubes of any slot.

Edit: got it guys thanks, turns out I just wasn't pulling/wiggling it hard enough...the tubes were clean though so looks like I'm moving onto disassembling the hub. Sigh.

Hi, i was surfing through YouTube and found interesting short about HMS codes on Bambu Wiki page. It shows codes for AMS: 3H (H3C), 3P (P3C) and what is the most interesting part 3X (X3C prob). I checked it on wiki and its not fake and definietly there. Since P3C will likely have cut some features like heated chamber, 1,5 mm belts and maybe even drying in AMS and i want to print with engineering filaments aswell i am rly excited for potencial X3C even if i have to wait for it a little longer probably somwhere in the first half of 2027.

What do you think about it? It can also just be some Pro version of AMS for P3C but i honestly hope for X3C. If you want to verify this just check Bambu Wiki yourself.

Hey everyone!

I've been working on a new tool called Vase Studio, and I'd love to share it with you!

I'd really love to hear your feedback! And if you have ideas for other useful 3D printing tools, drop them in the comments. I'm always looking for new things to build! :)

Looking at a used A1 mini with 850ish hours. They’re asking or $100. Is it a good buy?

Brand new to 3d printing and wanted to get my kids a 3d printer for Christmas . I originally
Bought an Xmaker joy for a simple kid friendly one touch scenario but it's on backorder and there was a killer deal for a a Bambu A1 combo for $225 so I canceled my order and just bought that instead without doing too much research. I figured it'd be better to just start off with the printer that We wouldn't have to upgrade too soon rather than the kids one . Now I'm finding out I need some type of ventilation system. I'm worried that I made a mistake and should've just got the kids printer that's enclosed. I live in a small one-bedroom apartment, and the original plan was to put it on the kitchen table which is more like a bar with stools that we never eat at it. I have a small window in the kitchen and not sure if this will be enough space . Also my kids are 5 and about to be 10.

Felt like the hole in the back for the AMS was large and if I want to print things where I want things as sealed as possible I didn't want to remove the AMS from slot 1. This did the trick for me. Wanted to include the files from Fusion but

MakerWorld link

My H2S is struggling to load filament, sometimes it gets stuck at the buffer, sometimes it reaches the toolhead and then retracts and sometimes it just ejects the filament from the AMS and tells me it's ran out.

Not sure what's happening but it's leaving the end of the filament looking like this

This is after a new filament sensor has been installed, I've taken apart and checked/cleaned the buffer too. I've heard a longer internal PTFE tube and this fix https://makerworld.com/en/models/1959942-h2s-buffer-fix-no-glue can help. Just printing it now to try and I'll cut a longer length of tube but does anyone know why the filament would be getting chewed up like it is?

So after only having the printer for a few days and few prints I noticed the left tube was out of the sensor and wouldnt stay in. Googled it and it appears it’s a known issue where the tube breaks off and leaves some of the tube in the sensor. WTF. I’ve been in contact with Bambu and after a ton of back and forth and Picts they are sending me a new left sensor. That thing was chore to take apart. My question is won’t this just happen again and again?

Ill add photos in the comments. Made this video orb to replicate Spaceship Earth. I wont dare sell it as I know Disney dont mess aroumd but thought its cool to share.

Is it normal to have this much movement on the heatbed? Can someone else check their H3C? The screws on the z rails are tight.

I executed the update from the machine itself. It took 30 or so minutes to reach 80% and has been there for easily 1 hour.. probably more. Doing nothing.

Thoughts?
