Haven't been printing much recently due to the heat but printing today I ran into a situation I thought I'd have to intervene in but, turns out, Bambu Lab had thought of this.
2 rolls of PETG, same make and colour, in my AMS 2 where 1 had minimal filament left on it. Set to auto switch when the almost empty one ran out, but as I was printing something that only need about 18g of filament, there was filament left in the tube going into the print head.#
I thought I'd have to manually pull it out but no, my H2S just purged the filament till the tube/nozzle was empty. I took my printer security, A Kawasaki Teddy Bear, off the top glass and had already removed the top glass in anticipation.
