Same thing is happening to my slot 2 ever since it had a tangle during a multicolor print with a rigid luminous pla. On startup it doesn’t detect / register until I tug on the filament, and then it will load.
I feel like the AMS needs to be taken apart but I don’t want to, or know what to look for.
I hope someone has a solution soon, otherwise it’s just an inconvenience at the time of start up
