I have 2 open 3d printers or bed-slingers, an old CR-10S pro, a new Ender 3 S1 Pro and my newest addition to the stable is a shiny new K1 Max, my first fully enclosed 3d printer, when I first bought the c-10 I blindly went on a filament buying frenzy and included in the 12 rolls of filament were 5 rolls of generic ABS as i planned on making a large 8 wd autonomous vehicle but i didn't realise you couldn't use it on an open printer, but finally I've found a printer that prints it amazingly i thought the K1 was a dud after buying (post buying depression), they call it 😁 but after nearly 14 successful prints including 4 successful ABS prints and 2 ABS failures I'm very happy with the results using PLA, PLA+, including silkand PETG i think it will be my workhorse.
