    Upgrading Chain driven CNC machine

    I am upgrading my Chain driven CNC machine to Rack and Pinion and I need to make Rack and Pinion drive plates like the one in the link below.
    I have Nema 23 425oz stepper motors.
    Does anyone have a drawing?
    The link below is to a page that has a file in .step and .igs file format but I can't use them, I am looking for a dxf file with measurements.
    TIA!!!

    Why not download the hobby version of Fusion 360, it's free. It will open the step file and you can dimension the part. Not sure if the hobby version of Fusion 360 will export dxf files. It used to, but they have limited some of the features.

    Hello Keith - That's a very easy part to draw up if you have CAD? Then no need for importing geometry... Peter
