  • It has worked fine. No issues with stability or leveling.

    Getting it to the right height is a bit of a hassle if you change material thickness frequently because in order to adjust it I have to remove the work piece and the honeycomb bed, turn the screw, add everything back to check if it’s right, and if not, repeat the process until it’s dialed in. Usually I am working with 3mm ply though so it’s not very often I need to fiddle with it, and when I need to work on something bulky it’s nice to be able to lift it without for added depth.


  • Hey there,

    Lots of things over the past few years. I will list them here and just let me know if you want more details.

    Most recently to oldest

    *Built a new stand/rolling cart with laptop drawer and monitor mount

    *Air hose regulator so I can easily toggle the air for the assist on and off without messing with the compressor valve

    *Microcontroller based thermostat that triggers LED lights when water for the coolant gets too hot

    *Cohesion 360 board so I can use lightburn and control power intensity from computer

    *Secondary power supply to run case upgrades

    *Extra case lights

    *Intake fans

    *Laser crosshairs

    *Drag chain for air assist and laser cross hair wires

  • Did you ever find the answer to your question?

    It will depend on your lenses and their corresponding focal length. Normally for cutting you want that focal point to hit halfway through the thickness of the material you are cutting. For etching slate I would put that focal length right at the surface.

    The standard focal length for a k40, which is the laser I use, with the stock lenses is 50.8mm I believe.
