Stinger V Micro Mill

While building my OX AI I found myself with left over v slot and thought to myself, what do I need that I can build using them? Well since I make a lot of my own PCB boards for projects I figured a micro PCB mill would fit the bill ;) With inspiration from the OX and OX AI I give you the Stinger V :)

    Curious what your cutting envelope is on this little guy?

    Not sure yet but it can be made as large as one wants.
    I just wanted to use up all my spare odds and ends.
    I would guess at about 12 x 14 inchs

    One worry I have about the Tension 20 design is that it appears to only be adjustable from the inside. Have you found instances where they are not easy to tweak on after they have been installed?

    Wondering if the adjustment grooves would be better placed in the plate itself, and the threads in the Tension 20 so you can tweak on stuff from the outside? Just a thought as I've studied over the screenshots.

    I did think of that but I would have needed to make two different tension designs so I did my best to allow room.
    You would need a stubby Allen wrench for tweaking down the road from wear.

    As long as you can get to them without disassembling stuff I suppose it is not a big deal. Excited to see some more details!

    This looks to be an awesome build. Can you share with us the lengths and cross sections of the extensions used as built? Also, I presume that this is designed for the NEMA 17 steppers. Thanks for sharing your talent with us.

    Hello. I have been reading up on all of the builds on this site. Yours seemed the most rigid. Can either this build or the OX build mill aluminum? Is it rigid enough to mill the OX side plates as the original CNC (with the liquid cooled spindle) did?

    I am looking into building a CNC router to be able to mill an unibody aluminum laptop case(like the macbook pro).

    Anything so far you wish you had done a little differently? Looking forward to an in depth review.

    As of yet not really, I need to replace all the v wheels still and finalize the controls before I can really say anything.
    It is super solid that's for sure and the Nema17 motors from the builds store are quite impressive.
    I'm also real happy with the Z leadscrew, moves smooth and fast even at 1/16 step rates :)
    I will say that I was hoping to find a smaller RC motor for the spindle that wouldn't take up to much space but really making the Y rails an extra 50 mm long would make up for the lost cutting space.

    So after some testing I know the X axis has 360mm of travel from limit switch to limit switch

    Also the RC Motor I plan on using for the spindle has arrived and I will be picking it up tonight.

    Same 890KV 5045 just a different style and make :)

    I will be saving the power supply I got from openbuilds store for my OX spindle and using 2 modified 250w rack mount power supply's one for the spindle and one for the controls.
