It attaches securely to the 2020 extrusion, keeping your RAMPS board stable and preventing stepper motor drivers from overheating. This helps prevent situation where stepper motors lose steps. The recommended screw size is M4-10mm, with two screws attached to the 2020 extrusion. You can connect fan power in one of two ways: 1. Connect the end stop port (5V-GND-Signal) or 2. Connect directly to a 12-volt power source To set up your driver fan, follow these steps: Step 1: Attach the RAMPS board and Arduino to DriverFan_B using M3 screws. Step 2: Securely attach the board shelf to the 2020 extrusion. Step 3: Mount the 70mm fan on DriverFan_A with an M4 screw. Step 4: Connect DriverFan_A and DriverFan_B directly. Step 5: Complete the setup by connecting remaining wires on RAMPS.
