Materials and Tools
Polarity refers to DC power - one of the conductors is positive (+) one is negative (- 'ground' on the controller board). Steps where polarity is a consideration are noted - pay close attention and make sure that the positive and negative conductors are in the correct locations before applying power to the printer!
Controller Power and Jumper Settings
- Braid the extruder drive wires.
- Braid the pairs of limit switch wires.
- Organize the wires from the end effector. Wire tie them to the Bowden sheath at regular intervals.
- The jumper at the bottom of the board enables autoresetting of the controller, which is required for uploading firmware. Set the jumper over both pins so they are shorted.
- Wires can be tucked behind the controller board and secured to the standoffs with wire ties to keep things neat. Secured and well bundled wires are less likely to get entangled.
