Final Wiring of the 3D Printing Modular Tool

Route the stepper motor wires and the hotend wires as shown. The wires should exit "up" towards where it would plug into the EMC02 motion controller board.

Use cable ties to hold the wires against the motor so that they don't rub on the Wade extruder large herringbone gear.

Route the wires to the EAT0004 module.

Note: We'll define which wires go to which terminal block positions in the next step.

Insert wires into the terminal block of the EAT0004 as shown.

Pin 1 and 2: Pin 1 goes to the hotend's black wire. Pin 2 goes to the hotend's red wire.

Pin 3: Stepper motor red wire

Pin 4: Stepper motor gray wire

Pin 5: Stepper motor yellow wire

Pin 6: Stepper motor green wire

Pin 7 and 8: Thermistor (twisted pair, color varies). NOTE: The thermistor doesn't have polarity, you may connect either pin as necessary.

NOTE: Some of the stepper motors had a different wire color coding. If your cables have the colors blue, green, red, and black, please use the cross-reference in the second picture displayed in this step.
