AMS Lite colours wrong in Bambu Studio

Real weird this.

On setting the filament on the A1 with AMS Lite i noticed Bambu studio would re-sync but get colours wrong, Basically not show what i had loaded correctly. I rebooted Printer quite a few times, even reloaded new filament and selected it but still Bambu Studio wouldn’t see it correctly. So i factory reset it and alls good again. I have noticed this quite a few time across 2 of them but today was factory reset day. I know yesterday they had an outage but id had this before that. I checked in with Orca Slicer and that also had the same reading as Studio and was wrong. So not really sure what it is.

Also one A1 is still showing external spool even though one isnt being used
Anybody else had this ?

Hello,
In the filament panel, there is a button to synchronize: doesn’t this button work?

For the external spool, as long as you don’t unload it, the filament remains the last loaded filament.

The manual spool was unloaded a week or so ago and I even reset the spool colour etc VIA the printer console so it was showing empty. If I loaded up the AMS configured colours etc and then go to PC when I resync it just come up with 3 colours it’s very weird . Factory reset kicked AMS into gear. I’ll go have another look once this prints finished tomorrow and see if I get the external spool to disappear. Even when I remove it from Bambu studio as shown as 5th spool it comes back even after the reset etc

This is a bug that existed in an earlier version of Bambu Studio that has regressed.

If you only have one printer, the sync button used to (when it worked) populate your filament pool with the ones on the AMS.

Since it regressed, it doesn’t recognise the filaments have been changed on the AMS.

This is true of the filament drop-down you use when changing or choosing a new filament from the AMS.

If you have more than one printer, the act of changing from one printer to another used to (when it worked) automatically checks the AMS of the selected printer so you could use the filament drop-down you use when changing or choosing a new filament from the AMS.

The sync button would know the currently installed filaments on the AMS and map those over.

The current situation usually means the drop-down filament chooser doesn’t list the AMS entries and the sync button maps an earlier set of filaments.

Thanks Malc sounds about right, I know when you use Multi device that also has an issue with filament sync, but I don’t use that anymore because of that

I’ll hang in for a fix I know it also happens on Orca so not sure who fix’s it software side

When the sync fails, normally a restart of the Studio application fixes it for me (after a resync in the fresh process).

i have noticed also that when doing say a hueforge picture with 4 colours the studio shows 8 or 9 colours and doesn’t print in sequence
