    Hi Paul.

    I received my Mini Gerbil in the mail yesterday and had it hooked up to my K40 in a few hours.
    I’m not the sharpest tool in the shed so it took me a while as I have a PSU Type II and had to be sure I had the cabling right.

    Wow! Buttery smooth action, accurate, fast and Lightburn recognized the unit and set the params instantly!

    I was giddy to say the least.

    Now I can actually do some cutting and engraving instead of debugging and banging my head against the wall.

    Thanks for a superior product and excellent purchase and shipping experience.
    You and your “team” are the best,
    Rob Hasanen, Canada.
