    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,

    I wanted to say that the board works perfectly on my new K40. Also, their support is excellent. Anytime I send a question Paul normally answers in a few minutes. Can say enough about this company. Highly recommend their controller for the K40 laser. After communicating with Paul I am going to change out the stepper drivers with the new 2208 drivers for even more smother movements and quieter.

      Thanks Rickm! Great to get feedback like this, can’t wait to see what you produce with your upgraded K40.
