    Re: small mill project.

    Nice work. Good to have a big mill when making a little one

    Have you used it enough to determine if the Y axis chip shield works? I didn’t know if chips would jamb up against the table?
    I may steel your idea for my Acer

    Re: small mill project.

    working on getting a spindle encoder mounted.. There isn't an easy way to mount an actual encoder - so I went with a gear and using gear tooth sensors..

    Machined a gear and mounted it to the spindle pully (the gear was something we had laying around...) 36 tooth + index



    This is where is is going to live...



    Testing the index hole... (pully flipped...)



    Making a bracket... (the gear tooth sensors will be potted when I am sure the quadrature signal looks good)
