Step 9: Limit Switches
Solder wire to the NC and common pins on each switch.
Put a little dab of gorilla glue on the switch then place it so the bearing block with hit the switch before going too far. A 1/2" in from the end of the rail is fine. Tape them in place, making sure they make good contact to the wood. The X axis ones were glued to the aluminum plate and it worked fine. If you have switches with holes for mounting you can drill and mount them that way. I couldn't find screws small enough for the mounting holes on the ones I had.
Run the wires up and out the hole for wires in the top of the case. I tacked them in place with wire staples.
Solder all of the common side switch wires into a 6 pin female header. Then solder the NC side wires to another 6 pin female header.
