Creality Swaps Purge ‘Poop’ for Sticks with New CFS-C for K1-series Printers

Creality has quietly listed the CFS-C, an iterative hardware solution designed to bring four-material printing to all K1 series printers without the invasive surgery required by previous kits. While the standard CFS launched as a native companion for the K2 Plus, K1 owners were later offered a complex upgrade path involving a complete extruder swap and other fiddly business. Except the 2025 versions, that is. Those machines were seemingly released in the knowledge the CFS-C would follow soon after, and had no direct compatibility with the upgrade kit.

Now, you can sidestep the upgrade kit entirely with the CFS-C. Costing the same as the regular CFS, $319, it moves the mechanical complexity of clean transitions to the outside of the printer’s frame. Unlike the original upgrade, which required a toolhead-mounted cutter to sever filament at the nozzle, the CFS-C handles the break at a larger buffer mounted to the back of the printer.

This allows for a “plug-and-play” installation via the CAN port, requiring only a firmware update and the mounting of the external hardware. It effectively trades a larger external footprint for a simpler installation process that avoids fiddling with the toolhead.

Unlike the regular CFS, the CFS-C cannot be networking with other CFS devices for more-than-four-color printing.
