That seems to be a poorly considered response. (Recognizing that if First stays with it, that will be the rule.) The control comes over the signal pin. So where the power comes from for the power line is immaterial from a control stand point. The MXP doesn't have a dedicated power pin for each PWM. The Vex motor pulls a lot of current at stall. One reason we stayed away from them in the past.

The motor controller are pulling their power straight from the PD board. Not much different conceptually than using a separate power supply for a servo
