Creality - CFS, Multicolor 3D Printer Filament System, Auto Filament Identification & Switch, Filament Run-Out Detection, Compatible with K2 Plus

Why did you pick this product vs others?: easy to install. Good quality, more issues than without but worth it! Clogging: More issues with clogging than without and a bit more difficult to clear out

Jammed because of user error, it works great when I'm not an idiot that day, I even did the heater mod where you 3d print the heater kit to take the guts out of the dual dryer/heater & jam it in the this CFS works pretty good

If you are simply updating a K2 to a CFS system, this will be a direct install solution. If you are attempting to upgrade your existing K1 and K1 Max to multicolor, understand that you are very much getting no support once you install the provided firmware. The firmware is borked and you won’t be able to run flow calibration. Creality doesn’t seem to actively support this, despite selling the upgrade kits.

Purchased for my son to upgrade his printer. Easy to set up. He loves it! Creality products have been great.

Cfs functions great. The upgrade kits for k1 series need some work so knocking down on comparability
