    Smile A2918SW circuit

    Hello eveyone
    first I would like to thank you all for the help you are giving and the support

    now my problem is
    I have a broken copier machine so I thought to get the motors and drivers from it

    the driver board that used in the machine is using the A2918SW drive IC

    I want to know how can I take this a part and use it to control the stepper motor from the parallel port of my pc
    I am using mach3 for controlling

    as I know the 2-9 data can be used in the port but where it should go on the IC?? to what pins?

    what is the voltage to operate the IC and if there is a circuit diagram to the IC? not the internal diagram but the full opreating diagram.

    please help me on that.
    thank you all in advance

    Hello dude.
    I just find in the same situation since last month i gott the same printer machine and the same board.
    Wait a week and i will try to figure it out.
    Should be not to dificult to use it.
    You are planing to use the motor wich came pluged to the board?
    I didnt like it too mach. May be i will look to set up for more powerfull motors.
    The schematic of a2918 suggest a peak current of 1.5 amps, and that should be enough for good torke results.
    Chears.
    See you next week.
