Hey folks. Getting ready to fire up the tinyG on he OpenBuilds plate machine for the initial communications testing. Quick question. I have a 24v fan that has 3 wires (red, yellow, black). I am wondering if the signal wire (yellow) should be removed? I tried to turn the board on once real quick and the fan did not spin with the signal wire attached. Is this normal if there is a signal wire connected (because it's not getting signal yet), or is this something I should just remove and it will fire the fan constantly? Thanks.
