Welcome to the forum.

What model of printer and AMS are you using? Double check that your are signed into the correct Bambu account with your printer is linked to it. Are you able to control your printer from Studio?

First easiest thing to do is check the connections between the printer and the AMS. Power cycle both of them. Then double check that the AMS is getting power.

Then follow the recommendations by @JonRaymond. It is hard to give an answer with little information.

I suggest screenshots as well.

  • Turn the printer and AMS off.

  • Remove the cable between the printer and AMS.

  • Wait a minute.

  • Plug the cable back in. Making sure it is correctly seated.

  • Turn them back on.

This normally fixes things.

I am using an Bambu A1 and the AMS Lite. I logged out and re entered my password 2 different times. I normally send programs for my laptop in the house to the A1. I have the App on the phone also.. I tried fixing it from the screen on the machine also . I unplugged it for awhile hoping it would reset or ask for a update and it still only shows External spool option.

I did not check the connection. I will do that when I get home. Thanks

Thanks . I did not think about unplugging the cable. I will do that when I get home. Thanks

Thanks Everyone, The fix was as simple as unplugging the AMS at the base of the printer and plugging it back in.

It is surprising how often this solves things. Cables being slightly loose is too often a factor.

35 years when I sold computers, it was always a floppy drive, fan, hard drive or cup cable coming loose that needed reseating.

You would think we would have learned how to make plugs and sockets that stayed together until we disconnected them.
