    EMC Lathe Handwheel

    Hi ,
    I want to control my lathe with EMC and servomotors and a uhu servodriver .
    The lathe has two handwheels build in , does someone knows in what kind of way this is possible to use the handwheels for convetionell turning , what HAL file I need ?

    Many thanks for your help

    Hans

    Do you mean you want to use the hand wheels from a conventional lathe?
    Or are you wanting to add electronic hand wheels (MPG) to the lathe?

    Adding a MPG is relativity easy.

    setting quadrature encoder wheels is straightforward in emc , but this depends to some extent on spare connections you have available , you will need 2 input pins at a minimum for A & B per wheel . see the axis jog hal commands .

    you dont say if your using a parrell port or mesa card for input i/o
    i'm not aware the uhu servodrive is compatable with EMC

    ok set up as per this link for each axis , should do the trick
    LinuxCNC.org - MPG Example

    if you set up in custom hal it will not be over written if you use stepconf

    set the pins approprately of course
    i presume your encoder wheels are quadrature
