    Great job @pedrofernandez this looks really cool. I like how you have the freedom on this design to adjust one side up and down to allow for different bottle shapes.

    this was a half time show idea !!! that rotary is for the franken40 and will be attached to the z axis structure but removable not permanently fixed like the k40 cube, profile is tall in order to be able to engrave large beer mugs with handles cheers..

    Let me know how you like it when it's finished. I use a chuck rotary and I love it. A few months back I purchased a rotary off of eBay with a similar design but I found it to be too jerky, especially when the print job was done and the machine would reset to the home position, the glass would just end up flying. Could have just been me though but I returned it. When I'm done with the current build (oh so close) I'm planning on making my own chuck rotary.

    I went ahead and added a link to the eBay listing. Hey, who knows if it turns out good you could make some money selling those. @$245 each there is a nice profit margin.

    Co2 Laser Rotary Engraver cutter attachment works with K40 x700 and others! | eBay

    This is for the DSP controller, the one for the Cohesion board on the K40 Cube is all set and running with a dual stepper on series using GRBL-LPC 4 axis external driver firmware.

    Hi Pedro,
    Very cool! A rotary Laser tool on a Laser cutter opens up so many more applications.
    Please keep us updated. Also, can you post a pic of the Yeti tumbler, that was worked on?
    It would be interesting to see the engraving detail. TIA.
    Regards,

    That looks great!
    I know very little about using lasers in reality, so it begs this question.
    I was thinking the other day about reflection? Do you not have to take care of any chance of reflection from the surface of, say, glass or similar?
    I know they do make a spray material for this sort of thing.
    Do you, or will you, be using something like that?

    Normally you want to protect your self more from the "welder flash" generated at contact with the material with this lasers than a reflection, but the machine is covered with acrylic sheet on the lid and all safety precautions are taken in mind, The product used for engraving the bare metal SS is called Laserbond, Cermark, and many other brands, even CRC dry moly lube from your local autoparts will work but as well
