Still on about the steppers but I notice that your pdf manual shows two different wire color configurations for the 8 wire motors. It's an off-chance but it may be worth checking (with a multimeter) the resistance of the stepper motor windings just to confirm that you have the correct center taps for the COM connections to the controller.
