This new version for the KP3S Pro allows you to use the entire bed surface (210x210), features a heat insert nut version, and supports ADXL, BLTouch, and inductive sensors. It is compatible with the KP3S Pro and KP3S Pro S1.

Attached, you can find the assembly instructions and Marlin 2.1.1 firmware for this mod. This firmware is for the F103 and F303 chips. If you have the latest version of the Kingroon, you need to compile the firmware for the STM32F4 chip (mks_robin_nano_v1_3_f4).
