The products in the Co Print Series II family are designed for broad compatibility. ChromaSet is compatible with all 3D printers not controlled by Klipper. KCM Set, on the other hand, is also compatible with printers that are controlled by Klipper (such as Creality K1, ELEGOO Neptune 4, etc.).You can see the main models that have been tested and are fully compatible below. However, models without Klipper are also compatible with ChromaSet.
