Athena Board Wiring

Materials and Tools
- Polarity refers to DC power - one of the conductors is positive (+) one is negative (- or 'gnd' or '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! Consequences of failing to observe polarity are expensive.
- There are three motors that control the movement of the printer. The motors are identified as U, V and W. When looking at the front, the extruder drive (with the fourth motor) is at the back of the printer. The U motor is on the left front, the V motor is on the right front and the W motor is in the back center on the apex with the extruder drive.
- The Athena Board has motor controllers and limit switches labeled for both Cartesian (x, y, z) and Delta (u, v, w) printers.
- With the printer upside-down, mark the motors 'u', 'v' and 'w': The w-apex has the extruder drive attached to it; u-v-w are clockwise.
- Loosen all of the screw terminals on the Athena Board and insert a small screwdriver into each terminal and wiggle it around to insure that it is fully open. This will greatly ease insertion of wires in later steps.
