CFS 2 compatible spool size range: diameter 197-202mm, thickness 50-68mm.
Applicable filament types: CFS 2 is compatible with most medium-hardness materials, such as PLA, PETG, ABS, PLA-CF, PET, ASA, HIPS, dried PVA, BVOH, etc.
PLA, PETG, ABS, PET, ASA, HIPS, PA, PC, PP, dried PVA, BVOH, etc., while also compatible with PLA-CF, PLA-GF, ABS-CF, ABS-GF, PETG-CF, PETG-GF; fiber-containing materials such as PPS-CF, PET, PET-CF, PC-CF, as well as flame-retardant grade material ABS-FR.
In the CFS 2 filament box, avoid using spools that are too wide or too narrow in diameter, irregular, or not smooth (e.g., with burrs or damage).
It is recommended to use the official Creality Hyper plastic spool series filaments, which have been extensively tested by us.
Paper spool filaments are not supported due to the risk of deformation from CFS 2's high-temperature drying at 85°C, and filaments with significantly deformed spools will affect normal printing and are also not supported.

A spool diameter that is too small will cause the spool to slip, bounce, and rotate unstably, resulting in retraction failure.
