    IK,R? I went up their page menu from there to DC motors to controllers and found USD264 was the cheapest reversible one they had.

    There might be better ways of doing a motor with a bit of go and speed control (even looking at a heavy duty hobby BLDC motor and an O-Drive), but I doubt you'd find cheaper than the trusty old treadmill.

    Treadmill motors are setup like RC car brush motor with the brushes advanced or retard in relation to the permanent magnets.
    I think the brush mount needs modifying to have zero advance for equal performance in forward or reverse.

    Wisdom results from foolishness!

    Also there is a resister you can remove if you don't want the feature that requires you set the pot to zero before going into run.

    I have the MC2100. I'd like to disable the feature that requires you to set the pot to zero before going into run. Which resistor do I need to remove.
