External spool automatic switching not working

Since one of the last updates I’m unable to switch between PLA and PETG for example. Normally I could just select PLA and print, then select PETG and print again. But now I get the error that for example I can’t print PETG because it thinks that there is PLA on the external spool. I’m only using the external spool.

So now I have to manually select PETG on the external spool before I can print by going to Device → external spool and select a PETG filament.

2 Bambu studio versions back (still 2.0) it was working fine from the prepare page.

Anyone know how to fix this, because it is very annoying.

I’ve now installed 2.0.1 again and now it’s working fine again.


I can now just select PLA or PETG within prepare and just click print plate. I don’t have to go to my device and manually switch the type on the external spool. So it seems to be a bug on the versions 2.0.2 and 2.0.3
