@SpencerVaughan You may use an unlimited amount of Y-Cables for motors provided four criteria are met:
*No more than 1 Y-cable is used per port (effectively, no more than two motors may be controlled per port, and also known as “No Y off a Y”).
*A Y-cable is not used on the 2-wire ports.
*No single motor is controlled by more than one port at once.
*Each motor plugged into a 3-wire port is plugged into its own motor controller
