the printer is telling you there is something stuck in the printer somewhere and not in the AMS. I had this happen too. until I pulled the extruder gears apart I didnt find the piece of plastic that was jamming it up.
May not be related to your actual cause but I was having the same issue (being told there was a manual spool issue when trying to print and I have never used it). Came across a wiki/support page that talked about all the reasons that this could happen and then in the comments down below someone mentioned AMS and the Bambu labs person responded, Load (in Bambu studio, device section I think) is not for AMS, only use it with an external reel. Hmmm, then why enable the optionâŚ
I had the same problem. To save you time in reading my journal, after hours here is what fixed it⌠I went to the printer screen, filament setting, and told it to unload filament slot 4 (That is where it though the ext. spool was. When I unloaded it, I discovered that the filament had broken about mid way in the boden tube. Now it works perfectly. I donât know if it was the broken filament, or if it got in a strange mode and had to be told to quit using the slot for the ext filament.
There is a setting that tells it to use a different filament if the filament runs out, I donât know but maybe that has something to do witlh it, but thatâs a long shot. Anyhow, it now works!!
Here is what you may try>⌠unload all of your filaments, mke sure the boden tubs are all clear, and reinstall filaments. This doesnât take long, a heck of a lot less time than the hours I spent in trying things.
Also, just leave one filament loaded in a slot that the printer has never though of as the external spool for the time being just to make sure things are back to normal
These are awesome printers, but they still have their quirks.l
Helped me exactly like this. Thank You
Have just come across this issue and after reading all the comments was still stuck, i turned off âauto refillâ and it stopped trying to detect the external spool.
my issue was after a major jam and had to pull the entire extruder aprat.
hope this helps someone
Happened with me, too.
Usually, taking the extruder apart, cleaning, and assembling will solve the problem. Also, check the top transparent throat with the filament sensor. The problem with my printer was that a tiny piece of filament string stuck behind that metal little magnetic pin in the throat that detects the filament, it had not gone back to its place when there was no filament in the throat. It is where the filament tube attaches to the extruder on the top. When a filament is in, the little metal pin pushes towards the sensor, and it should go back when it is empty. That little stuck filament prevented that, making the printer think there is something in it from the external spool. Clean that whole part and check without the sensor plate if it works properly when you push and pull a piece of filament.
Iâm having the same issue. My spool slot #3 will not recognize there is filament in it, and keep saying that it is the external roll. However, I have no external roll, only the 4 rolls from the AMS lite. I can run filament all the way through the third spools tube and it would even print if I said it was the âexternal spoolâ. 1,2,4 all recognize and auto feed the filament but not 3. So it canât be blocked if it printed filament from spool 3 can it? Iâve completed a hard reset, factory reset, switched filament tubes on #3, taken the extruder head off, unplugged the usb c cable, reset the external roll filament from the bambu software - I am at a loss now.
You can try resetting slot 3 in your AMS. Then reenter the details of your role of filament. That might work.
This might have to be performed from the printer screen.
