Step 1: Assembling the base. Make electrical connections

Step 1: Trimming Power Leads on Power Supply

'''DO NOT DO ANY ELECTRICAL WIRING OR CONNECTIONS WHILE THE POWER SUPPLY IS PLUGGED IN. IMPORTANT: UNPLUG THE POWER SUPPLY BEFORE PERFORMING AND WIRING OR REWIRING.'''

Follow the pictorials to the left to trim the ends off of the appropriate power leads. Trim 3/8" of the wire shielding off the ends of the wires that are used. Please electrical tape the ends of any cut but unused wires.

Bundle together the black wires as shown. This are placed into a single terminal block slot on the axis control boards. (The black wires are ground wires)

Wire nut together the specific green and black leads shown securely. These leads control whether the power supply will turn on when connected to the wall outlet. This is the first thing to check if the power supply does not appear to get turning on when connected to power and the power switch is in the on position.

Step 2: Making parellel cable connections

First secure the DB25 connector onto the ribbon cable. Make sure to align the pin 1 indicator shown in the picture above so that it is on the same side as the red colored wire on the ribbon.

Peel each wire off the ribbon back to about 8" in length.

Number each wire with a piece of tape, starting at 1 for the red wire and counting up all the way to the otherside.

Mount the axis control boards in the top of the powerbox after seating the power supply in the bottom compartment. Use the shortest fine point screws supplied to screw the control boards directly to the wooden divider. Label each board position X, Y and Z as shown. (There is not difference between the supplied boards). The 4 pin terminal on the bottom should face the front of the power box (the side with the clearances for the power supply fan and power switch.)

Wire the power connectors from the power supply into the terminals as shown. The yellow wire from the power supply is 12V and goes into the top terminal slows as shown. The black wires twisted together are ground and go into the 2nd down terminal slot as shown. The red wires are 5V and go into the 3rd down terminal slot as shown.

Wire the motor leads into the bottom terminals as shown. Note that one of the motors, the Z, is reversed. This is necessary so that it orients correctly with the default EMC2 configuration. DO NOT EVER ADJUST MOTOR WIRING WHILE THE POWER IS ON, THIS CAN RESULT IN DANGEROUS ELECTRICAL CONDITIONS AND HEAT.

The wiring of the parallel port lines is shown below in tables.
