    Thanks for that, high current version it is then

    Definitely not me

    Removing the post does tend to make me look guilty though

    Sounds good, I'll go with the high current option.

    Stepper motor wiring...

    When wiring a stepper motor, is there any performance hit when wiring bi-polar series or bi-polar parallel?

    Series takes 2.1A and parallel takes 4.2A on my motors but will one way perform better over the other way??


    Thanks
