    Hi all, I have been researching a 3 axis stepper motor kit, from the advice I have been given this forum, I have decided to go with a 80v set up, have seen some stepper motors from cnc4you, they are 8 wire 4Nm model number 60BYG401-03, and also the drivers to match which are 6.0A, 80V CNC Microstepping CW8060, also from cnc4you, i need advice on the the psu and the breakout board to with the motors and drivers, I am not quite sure which would best, either from cnc4you or elsewhere. Any advice would be very much appreciated. Thanks Paul

    Hi Paul53,

    Checkout post #95 in my buildlog.

    Clive S pointed out the parts for a diy psu.


    https://r.tapatalk.com/shareLink?url...2&share_type=t

    It is excelent advice.

    When i measure voltage there is only about 2 volt drop at max speed running all 4 4nm nema 23 steppers.

    I have 235volt input 72volt output rectified.
    I have 3 4700 capacitors.

    Did you say you have the UC300eth ?

    Best board out there is sold by:

    https://www.cncroom.com/interface-cards/uc300eth-ub1

    Also sold separately.

    https://www.cncroom.com/interface-cards/ub1

    It is expensive though.

    I went for cheap dual 5 axis boards.
    I added cheap relays.


    I have all the IO i need.

    There was some tinkering needed to run 24v signaling icw cheap boards.

    UB1 has native 24v support for IO.

    For the machine I think you have I would just use a simple bob to get you going if the PC has a PP https://www.ebay.co.uk/itm/5-Axis-CN...gAAOSwHUlbkLzl

    Hi Clive, regarding the machine, I have basically stripped it down, I am rebuilding the whole thing, replacing wooden frame with 10mm aluminium plate, everything is being made out of this, the spindle mount, side supports etc, the only thing I am using is the spindle (water cooled) and the inverter, so basically starting again, haven't decided whether to mount all the drivers etc in a pc case or get/make a purpose built control box
