    RE: different output power at different ports? —Elizabeth Mabrey
   (...) Without any precious hardware verification, this is what I did: - symptom: motor C was not able to make turn as well as motor A can - troubleshooting steps: a) to ensure even load on both motor ports, I removed all other attachments, and left (...)

        RE: different output power at different ports? —Elizabeth Mabrey
     Sorry... I meant "precise hardware verification" not precious. I do not the equipment to measure them. Any suggestion, other than getting extra hardware like a power analyzer, for trouble shooting? Trouble shooting is always (well, almost always) (...)

        Re: different output power at different ports? —danny staple
   (...) Okay - did you try a simple program going in a straight line, and check how much it veered after a few meters? Unfortunately - it does not sound an entirely unlikely problem - if there are variations between the h-bridges (general (...)

        Re: different output power at different ports? —Ralph Hempel
   (...) This sounds to me like a good tactic. Your program might have some issue with turning in one direction vs another. (...) I also have trouble believing variations in parts (except the motors themselves) will cause this much difference.
