ID:	30861 do i keep this board as it has the X Y Z axis attached

    UPDATE.....Have connected Axbb-e to the 5v and 12v power psu and also connected network, so now need to build a bigger controller box so all will fit in.

    That is an all-in-one board with controller and motor drives combined so you can't use it because you can't control the drives.

    To use with the AXBB-E you will need separate drives.
    -use common sense, if you lack it, there is no software to help that.

    Cheers Jazz ...will have a look about and order some.

    My stepper motor has this on it NN MOTOR 57HS7416-15-14B 80 Does that mean anything , when I did a search it didn't come back with much except nema 23, so do i order drivers for a nema 23.
    Cheers

    Depends on what you want to do and the motor spec. Model number not showing anything so double check you have it right.
    What are it's dimensions, that may also give us a clue on it.

    Personally, I never run my nema23 motors below 60vdc anymore which requires the nema34 drivers DM860T instead. The velocity you can achieve is so much better.

    This is typical of Chinese machines as they fit oddball motors which you probably won't find any info about. However, doesn't really matter too much because you will only have at best 36Vdc from the PSU so any drive with a 50Vdc max rating will work for you. Because you can't tell the motor current a little trial and error will be needed on the amps but this is no big deal as they will just run hot if too high and stall easily if too low.

    These will work fine for what you need and will work miles better than what you had before. But before buying it's worth checking the voltage coming from the PSU

    If you find that your max velocity is below what you would like, swap out the 36v for a 48v.
    I'd have gone for the DM556:

    I use DM542T drivers at 36V on a pair of 3NM NEMA23 motors to pull an 800mm wide welded steel gantry with a 2.2KW spindle on it. It's fairly weighty but will rapid at over 10/min with reasonable acceleration so they'll probably do.
    However, there is always a case for spending a bit more on something over-specified for your present needs if you might want to upgrade other parts in the future. It's a balance between spend more now to save in future.

    To get a bit more info on the motors you could look at the spec of similar sized motors from stepperonline and others. Measure the winding resistance of the motors you have and look for a match in both resistance and physical size. It's not a guarantee they're the same current rating but will give you somewhere to start.

    An optimist says the glass is half full, a pessimist says the glass is half empty, an engineer says you're using the wrong sized glass.

    Hi All,
    been having a go at building onto the AXXB-E attached are some pics and would like advice as to were I have gone wrong on the stepper drives, also the 3 wires lying by the AXXB-E are from the VFD av1 grnd and +10v were do i attach these to the AXBB-E, also emergency stop and pump.
    All the advice i have had up to now is much appreciated.
