MKS 3MOS Module – Addon 3 FANs to your Board

This module repurposes a stepper socket to 3 extra MOSFETs that can handle up to 2A each. It pulls power from the board VMOT pin to power the fans and uses the EN, STEP, and DIR pins from the stepper socket to turn on/off the mosfets.

This is a DIY part so no technical support is included with this product. YOU MUST HAVE AN OPEN AND NOT USED STEPPER DRIVER SOCKET TO USE THIS.

If using the MKS Monster 8 V2 and our Unified 2 Firmware there are extra options in the firmware to use this in the DRIVER7 (the last one) position on the board.
