Thats the part that puzzles me. As I hate to be told the system will know . . . really will it really know? You are going to play with them in a month or so, lucky I have 8 more to go before I need to worry about it. Im already getting the sequencing worked out so waiting for the hardware is no big deal. My goal is 3 2810 strips or pixels, makes no difference to me which way I go as they will all be straight runs. I appreciate any input you add to this or Ill just bug you in a month if you have come up with the answers.
