I'm using the parallax servo software, with the parallax 16 usb servo controller, I have two servos that work just fine with it, then I'm using the hb-25 to hook a 12v motor to the system, but I cant seem to get it to work. the motor is a 12v 2 amp motor with gear box,

I have the signal from the servo controller running the the motor hb-25, I have 12v 2amp, running to the bb 25, and then pos and neg wires running to the motor. but the motor isn't getting a signal gtom the motor controller. any advice? I need to get this up and running today.


thank you
Jason MIller

    Make sure all your grounds are tied together.

    not sure how to do that, it only has two grounds, one that goes to the servo controller which has a 6v power suply and one that comes from the 12v power that powers the motor controller and the 12v 2 amp motor. if I tie them together I break the flow on one of them.


    so from the 6v servo controller I have signal and ground running, no power, to the motor controller, then I have 12v 2 amp power running to the power in prongs on the motor controller, then I have power and ground, or + amd - running to the motor which is a servo city gear motor Torque of 55 inch pounds.
