The last three cables are the collision board (limit switch) cables. As you have already
attached the limit switch ends, thread the wires along the same path as the other wires-
out through the top plate and back through the side shield. The connectors are pressed
into the sockets on the collision board- use the X, Y and Z tower markings to ensure
the correct cable is installed. The connections at the main board go to the X+, Y+ and
Z+ limit switch position (as the limit switches are at the maximum X, Y and Z
positons).
