    This may sound a stupid question but I am new to playing with stepper motors and drivers. I am hoping someone can help with my query. Basically I bought some stepper driver boards off Fleebay. The drivers have 6 connectors for the outputs. These are:-

    - Enable +
    - Enable -
    - Direction +
    - Direction -
    - Pulse +
    - Pulse -

    I only have 4 connectors on my breakout board, these are

    XE - enable?
    XD - direction
    XS - Pulse/step
    XN - Ground

    Would I be right to assume the three negatives are linked together and then back to XN?

    Generally enable does not need to be used so just ling the -ve on the others. ..Clive

    I learnt my lesson with floating inputs 30 years ago, so my question is - is there usually built in bias towards the enabled state in stepper drivers ?

    Hi Clive,

    Thanks I shall give it a go, see what happens.

    In my Leadshine manual it says, High level for enabling, low level for disabling. Usually left unconnected (enabled)

    So the default state you might say is 'enabled', I expect that rather than floating, the input has a pull-up resistor to keep it 'high'

    Spelling mistakes are not intentional, I only seem to see them some time after I've posted

    Thanks' for that it saved me replying I do use my enables but as you say it is not necessary. ..Clive

    So let me get this correct. Do I only connect the following:-

    Direction - to XD
    Pulse - to XS

    All other connections are left disconnected.

  8. There are a couple of options but the common one is:

    Pulse+ to XS, Pulse- to XN
    Direction+ to XD, Direction- to XN
