Could you upload the log of the machine and Studio? We need that to target the issue.

Same here. Project doesn't seem to matter.

I do have the same issue here. Beta 3 of the slicer and last firmware on the machine.

I cannot upload here the log as they are too big of a file now.

[mtwomey]

My studio logs were also huge, so I cleared them out and restarted studio and recreated the issue. It doesn't produce any logs - I think that is because I literally just open studio and select the filament and it happens. There is no project started and nothing done anywhere at all. I am getting the x1c logs for you though.

How should I send you the machine logs? They are 385mb.

Can't up load machine log file, to big. (376 MB)

Okay, thank you for your log. I understand now. Will be fixed on the printer firmware.

[QingZhangBambu]

will the custom filament be selected displayed in AMS later? or just be "?" forever.

[vndk36]

For my part, it stays with the correct custom name and colour for 10 seconds or so and then goes back to "?". I managed to rapidly click on the "prepare" tab of the slicer and I can see the correct custom filament in the filament list of the machine. However, after 10sec on this tab or the device tab, it reverts back to ?

@DanBao-Bambu I know that it's two separate departments (software, firmware) but... can you ask the firmware department when a new firmware will be released to fix this issue?

[man55]

Same here.
The only chance to select a custom filament is to do so directly from the printer screen.

[MrDB42]

@man55 Weird. I couldn't even do that, until I did a firmware reset on the printer just now. Interesting... But at least now I can select a custom filament.
