If I put remnant rolls of red in slots 1 and 2 in the AMS and both run out, I should be able to add more red to slot 1 and press retry rather than needing to put the roll in slot 2.
I forget the exact wording of the prompt on the printer but it essentially asks tells you it ran out and to add more. However if both slot 1 and 2 ran out it’ll only continue working if you add more to slot 2 as that was the most recent to run out. If they’re both set to the same filament, I should be able to add more to slot 1 (Or both), and it start from slot 1 again.
