Creality K1/K1 max fan mount for extra 4010 fan

thingiverse

This bracket mounts the mainboard fan that is currently bolted to the bottom cover directly to the mainboard and adds an additional 4010 fan. You remove 3 mainboard mounting screws and replace with bracket & 3 M3 SHCS. I wanted to be able to cool the MCU when the printer is idle but since the current mainboard fan is controlled with the heatbreak fan, I had to connect a second fan to the extra fan port on the mainboard. This fan can be temperature controlled. You will need root access so as to modify the printer.cfg file.I re-mixed this bracket from Henlor: https://www.printables.com/model/540070-motherboard-fan-mount-mk2-collection-creality-k1-scomment out this section of the printer.cfg:[temperature_sensor mcu_temp]sensor_type: temperature_mcumin_temp: 0max_temp: 100Add this section to the printer.cfg[temperature_fan MCU_fan]pin: PA0kick_start_time: 0.8off_below: 0.1max_power: 1.0sensor_type: temperature_mcucontrol: pidmin_temp: 0max_temp: 100pid_kp: 1.0pid_ki: 0.5pid_kd: 2.0min_speed: 0.1max_speed: 0.8target_temp: 38
