Just upgraded to the K2 combo and selling my K1 with CFS. Rooted with klipper access for full tuning and16-tooth pully mod to reduce vfa’s. Supports multi color and multi material printing. Fully enclosed for engineering grade filaments such as ASA, ABS, and PC/Nylon. Everything works great - and the printer has been reliable for me. Selling both the printer and CFS for $400- looking for a quick sell. Cash only - text or message for more info
