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

the Install for my k1se was pretty smooth and everything made sense. In terms of the CFS it does its job and it will auto feed well. Though it does seem like a few filaments have trouble and not because of the filament itself but certain spool brands just don’t fit in there well but other multifilament systems like this have the same issue so meh. Still great and works well with most of what i print with and keeps with other brands with similar multicolor filament systems

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

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.

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

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