r/BambuLabA1

Hi all! I just wanted to make a post and ask the community of their favorite or fun upgrades they have printed for their A1. Right now I have a toolbox, a nice display for my swatches, and a filament measure. I’m also planning to print something for removing my ptf tubes when I need to and might look into a cable chain just for fun as I’m kind of bore and in a spot of not knowing what to print right now that would be semi useful. So what are some things you’ve made?

I'm 15 and I really want a bambu lab but I've got a few questions I'm hoping some of you guys could answer

- Am I too young, ( I do have some experience and I'm confident when it comes to machines)

- Bambu lab A1 or A1 mini

- What do I need to know about filament drying

- Are they reliable printers and continuously produce successful prints

- Are they fire hazards

- Is AMS lite necessary

- Will it be safe to leave the printer in the dining room. We usually keep the garden doors open throughout the day for better air circulation in the dining room

- I have a ginger cat, he's pretty curious but also shy at the same time. Is it safe around him. I fear he'll climb all over it, maybe step in the hot bed, his hair getting stuck in prints. He does go outside for most of the day and it's not a problem to keep him out of the dining room but there will be times he'll slip in without me noticing bearing in mind the fact that the garden doors are constantly open

Thanks so much for any help

Hey. My screen keeps freezing and of turning off and not coming back on. I can still monitor it from my phone, but has anyone had this issue? I am guessing it is a software update issue?

So im planning on buying this 3D-printer but I do have cats walking around my room. They are pretty used to sleeping in my room and I honestly also dont want to force them out of my room if I do decide to place the printer in my room. Should i be worried that the printer malfunctions because of car hair for example? I do plan on closing the door when i am printing but not whilst its not. Anyone that has cats or pets in their room while they are still using the printer, could you tell me if its a smart decision to buy this printer or should I choose a enclosed one? Otherwise, im thinking of buying the p1s isntead.

Hey everyone,

I just got a brand new Bambu Lab A1 with AMS Lite. For the first 3 days, it worked flawlessly, but then it started giving me continuous SD card errors mid-print. Whenever I hit "continue," the extruder would just go back to its last position and freeze there. This happened around the exact same layer height on three different prints, forcing me to pause and look for solutions.

After reading some forum posts suggesting the latest firmware update might be causing SD card glitches, I decided to downgrade the firmware to the previous version.

The first print after the downgrade seemed fine until it reached the very last layers. The infill/lines didn't complete; the toolhead suddenly stopped, moved back and forth erratically, and then moved all the way to the back of the Y-axis. It literally slammed the hotend straight into the plastic assembly behind the heatbed (the purge/wiper area) and dug right into it.

The plastic started melting and smoking, so I panic-shut down the machine. After turning it back on, there were absolutely no error codes on the screen.

The hotend or the assembly might be bent, and the back plastic is physically damaged. Since this machine is only a few days old, I'm seriously considering returning it.

Has anyone experienced a firmware downgrade causing a catastrophic head crash like this? Do you think it’s a faulty mainboard/sensor, or should I just pack it up and open a return ticket with Bambu Lab immediately?

Thanks in advance.

Since a recent firmware update, my A1 does something odd on the first print after a full power off:

- I switch the printer fully off with the rear power switch.

- On the next boot, when I start the first print, it behaves as if filament was just loaded. It pauses, asks me to confirm whether filament is extruded, then runs a purge before continuing.

- After I confirm, the print continues normally.

- Every following print in that same session is fine: no prompt, no extra purge.

- It only comes back after another full power off and on.

So it is tied to a cold boot, not to individual prints. The filament is loaded the whole time and never physically changes.

Setup:

- Printer: Bambu Lab A1

- Firmware: latest

- Slicer: Bambu Studio

Questions:

- Anyone else seeing this after the latest firmware?

- Is it a known bug or intended behavior after a power cycle?

- Any setting or workaround to stop the confirmation prompt and purge on cold boot, short of never fully powering off?

Thanks.

Every A1 & A1 mini user (and probably every bambu printer user) has or will have this traumatic experience. Are you close to having one? Let's check. Printer on => settings=> SD Card. There you will find a screen with buttons Format and Eject along with the storage amount & remainder with a bar graph. If that bar graph is approaching full, you'll be experiencing this fail to print soon enough.

2 Solutions: format and destroy the OEM firmware stored on the OEM sd card & all print gcodes, or, remove thru eject sequence and attach to a computer. From here, open in a file management app and move any gcode & the OEM firmware files you want into the computer or other storage. device. Properly remove the card from the computer and re-insert into the printer. Now, select format. Plenty of storage room now.

Edit: I should add when not to remove nor format the card. Do not attempt to properly remove or clean or format the card while printing. Effecting the card during printing will end the print in bad ways, similar to removing a card from any devise during it's use.

The printer does need to be turned on to access the card's storage amounts and the eject & format options.

The card can be removed and inserted while printer is turned off.
