A1 can't print due to error

Bambu Lab A1 Series Troubleshooting
21

@RIK_DESIGN oh … okay … thought it’s all moreless the same.

22

Has anyone found a solution to this? I’m currently having the same problem

23

Same problem! Any solution yet?

24

Yeah, Bambu sent me replacement parts after I opened a ticket about it. I swapped the parts and it printed fine after.

25

Did anyone find a solution?
I spent several hours and $$$ trying to troubleshoot this. Things I have tried so far:

  • Dismantled and cleaned the extruder;
  • Changed the nozzle;
  • Changed the filament sensor (twice!);
  • Changed the TH Motherboard;
  • Changed the AMS Lite Filament Hub;
  • Did several factory resets.

I just opened a ticket with customer support, but I’m not holding my breath because of the bad reputation it gets on Reddit…

After watching this video (*), I believe my issue comes from the magnet used in conjunction with the filament sensor, which doesn’t retain its off position.

I tried to use some lubricant on it as suggested in the video, but it didn’t do the trick.

I informed Bambu’s customer service of the defective magnet part, I’ll update my post when I get an answer.

(*) For some reason I can’t include a link in this post, just search " I FIXED My Bambu Lab A1 Mini!" on the “3D Printing Nerd” channel on Youtube.

For anyone with this issue: the Bambu Lab support has been great. They answered my ticket quickly and sent me the part I needed.

My issue was the filament sensor base: the magnet used to sense the presence of the filament (in conjunction with the filament sensor) wasn’t returning to its off position when no filament was in the base, so I needed to change it (see the video I mentioned above, it was really helpful to understand what was wrong).

That’s too bad this part is not on sale in the shop, hopefully Bambu Lab will add it.
