My day 1 experience on A1 Mini

Hi all,

I received my A1 mini combo yesterday, still waiting the the mega pack come later to test the bigger nozzle.

Here is my day 1 experience after near finish a 1kg PETG pool.

  1. Very easy setup, took me less then 15 mins to get the printer up and running.
  2. Default print speed is FAST and output looks good without any tuning. I moved from Ender 5 to A1 Mini due to ongoing printing problem in my ED5. I did number of PETG prints with fan speed max to 60%. The noise level is acceptable when fan on low speed.
  3. A lot of filament waste even print on single colour without using AMS. It still waste a lot of filament during pre-print testing.
  4. Print plate looks small but still able to print majority of my 3D file.
  5. I haven’t print PLA yet, but it working fine on PETG on default profile, however, I need to maually clean up the nozzle in the pre-print testing period to avoid nozzle block.
  6. I missed the kippler + obico.



Got the A1 a few days ago, lots to like about it for sure.

Some issues for me though.

Firmware would not update using the A1 touchscreen, it just kept trying and not working. Running the firmware update through Bambu handy app worked for me though.

I’m getting a lot of failed prints, two times big layer shifts and twice more what looks like parts lifting mid print and saw the nozzle collide with the part.

Have washed build plate and used Bambu liquid glue and it still happens.

Using a straight ruler across the bed it looks like the back left is notably uneven, this is where most problems have occurred. Thinking this is maybe too much.

I have had bed adhesion issues on my p1ps but washing the plate and using glue has been rock solid fix but not so on the A1.

Not really sure what to try next.

You should definitely open a ticket with support.
If the bed is warped significantly, they’ll likely send a replacement. Granted, you’ll have to go through a bit of work to prove it to them first.

Honestly, i’m kinda surprised this would happen on a bed this small. I can understand some of the QC issues they had with the beds of the X/P series printers, but on a 180mm bed?
Hopefully this is just a one-off issue.

I remember their is a bed re-leveling guide in Bambu Wiki, you can follow the instruction to re-level your bed, it is quite easy and shouldn’t take much time.

Hope it can fix your problem. I only had layer shift problem once, but it fixed after I re-slice the model.

Thanks, I’ll look that up and give it a try.

I have since done a couple of individual prints more in the centre of the build plate with four colours and two successful prints in a row, as well as a single colour print that came out well so I think I do just need a slight adjustment in the corner.
