Kingroon KP3S Soft flexible filament upgrade

thingiverse

Things to adapt printer for using soft flexible filament. Must be on direct Titan extruder. First - you must eliminate any dead space on the filament way after gear of extruder and before nozzle. I used adapter and PTFE tube for Titan extruder. The tube should be whole, straight and have no cuts, breaks of bents before the throat tube of hot end.

Used: 636 Bearing (6mm AirSoft BB's) https://www.thingiverse.com/thing:2468780 Spool Holder for Kingroon KP3 https://www.thingiverse.com/thing:4320932 Bobber for spool, you will need M5 rod and 2 friction nuts. If you do not nave rod - saw heads from two M5 bolts and glue them inside bobber. Chech your spool inside diameter to adjust bobber before printing. Damper is optional. Third important step you should consult your filament manufacturer to adjust the temperature of extruder. Even 5 Celsius interval dramatically change behaviour of soft flexible filament. Another things you should keep in your head is minimal retractions, adequate cooling, and low printing speed. Good luck !
