How to save yourself an hour when testing your RAMPS

Make sure you set the correct pins in the firmware before flashing.  I'd like to say stuff just magically works after that, but I think being clueless about the pin settings made me recheck all my wiring and connections so it just appeared to work after finally getting the pins right.

More testing tips:
  • Disable endstops in firmware. It'll freak you out when your motors only move in one direction.
  • Test controllers and steppers individually to avoid blowing up more than one thing at a time.
  • Here is the quick way of figuring out how to wire your stepper.
  • Make sure you order pins with your connecter housing (otherwise you'll be left scrounging for connectors in your computer cases).  My fingers still hurt from taking connectors apart.
