Hi Everyone.#

CR4CU220812S12_ota_X2000E_V1.1.0.27.20251225.img is the latest firmware for K1 Max with the upgraded motherboard.

I installed the v2 firmware originally just to support the CFS , but is there a way of using this new latest V1.1.0.27.20251225 firmware which supports the CFS with my new upgraded motherboard. I have upgraded the motors and pulleys to support the new motherboard version CR4CU220812S12. There really isn’t any information regarding this anywhere and i don’t want to brick my machine. There must be a reason why they uploaded it. Anyone got a clue.

cheers

I having the same issue with my K1C converted to use CFS. They shipped a build for the board ending in 11 and didn’t mention it in the instructions. Huge bummer.
