The 2 blue leds are flashing @ 1 second intervals and one or more of the (can’t determine which one) stepper motors is activating in time with the leds. I’ve pressed the reset button but that has not cured it. No other leds are lit.
Received the board yesterday. Is this a dud? Or is this something that can be corrected?
Go back to support. You had an original problem to replace the board so that may still be there or as you said you got a dud. Either way support is the one to help to fix the original problem and/or replace the new board.
