    Thanks, we had been looking for a solution for a while and I made the suggestion to look at home built CNCs. so far it has worked out well. Next we are planning to add the interface and potentially some kind of water dispenser at the end of the blade to keep the tools cool.

    Very nice! I always love a purpose built machine like this and that you married the old and new together is really cool to me. Thanks for sharing looking forward to updates as they happen

    I wonder why the Y C-beam is so long. Isn't it way past the max swing of the lathe? Are you going to use some special cutting tools?

    the y axis is the full length of the table that the lathe is mounted to, the initial idea was that the x-axis was going to be manually controlled so we would have been able to use a bit more of the length, but we have since added a stepper motor to the x-axis. currently we have a small aluminum vise mounted and several different knives (depending on the type of rubber we are cutting). This rig basically replaces the need for a $100,000+ mitchel cutter machine and we can generally get cuts accurate to +/- .070".

    Nick,

    if you're still out there, would you please provides some advice on the software you are using? I have a similar build (although i kinda like yours better), and I'm having a difficult time running toolpaths in fusion 360. I've attached my file, in case anyone out there may be able to help.

    Thanks,
    AMW

    the only software I'm using is Open Builds Control, I figured out how to write the jog commands in grbl and have been using a series of simple jog commands saved as a macro to run my cuts.

    example: this moves my blade into the material to cut, backs it out , moves it to the next cut, repeats then returns everything to zero.

    $J=G91G20y.87F10
    $J=G91G20y-.87F100
    $J=G91G20x2.23F5000
    $J=G91G20y.87F10
    $J=G91G20y-.87F100
    $J=G90G20Y0F5000
    $J=G90G20X0F5000
