    So I just ordered parts for this open source mill after seeing Tom's Live Stream build of it on YouTube (which is currently missing from youtube at the moment, will post link when it is up again)

    [​IMG]

    Here is the link to the Instructables page for the build: http://www.instructables.com/id/How-to-Build-the-Sienci-Mill-One-Desktop-CNC/

    I am sure I will modify it slightly on the way such as the build area, using thicker MDF and metric angle...but the basics are all there and should be quite affordable compared to using V-slot and still prove "accurate enough" until I fork out for a real Mill down the track :D

    Currently awaiting arrival:

    - 3x 500mm Anti-Backlash lead screws
    - 3x 5-8mm solid couplers
    - 20x 5mm V-wheels

    And already have waiting:

    - Arduino CNC shield & drivers
    - 3x NEMA-17 Steppers
    - an ER11 collet and shaft setup and hobby 1450KV brushless motor with 30A ESC to start with then will upgrade to a Makita or similar trim router when all working...

    now I just need to source the Angie and MDF and then can modify/re-design the printed parts off the thingiverse page for the Sienci to suit metric...

    Subbed, looking forward to seeing this pan out like your HyperCube 3D Printer :thumbup:

    When can I send you by 3D jobs :weirdo::tongue:

    Where did you source the eccentric nuts from? My MPCNC build is stalled out because i haven't found the time to go get the steel pipe yet, but i have been keeping an eye on the MillOne in the meantime.

    Got them from AliExpress, much cheaper than MakerStore...much much...

    bought a fair few of them so hit me up when i post a pic of them if you still need some :D

    Neat design, I'll keep an eye out.

    Cool project, subbed to see how it goes. :thumbup:

    I'd love to build one, but if I'm being honest with myself it would really be like trying to walk before crawling.

    I should probably learn how to use a lathe first.

    Hell, buying a drill press would be a good enough start.

    :lol:

    looks like a nifty design, so envious of those who go through with making little CNC routers/mills - 3D printers are great but it's hard to compete with the ability to cut through metal.


    good luck with the build and keep us posted on progress.

    Looks like a fun build! Subbed to hear how it goes and see how it performs! :)

    Whats the expected total cost? Any idea at this stage?

    Well to my surprise the first parcel has shown up from China already...

    that was less than 10 days and the rods are straight despite the lack of packaging!

    A rough guesstimate should put it under or around $250

    (not including the router obviously which is $195 from Bunnings)

    I'll probably have a crack at this if I can find someone with a mill or something to do the required accurate holes.

    (Or print a template and build a baby drill press for a Proxxon/Dremel etc)

    I plan to laser cut the holes as a template in MDF then just clamp and drill them into ally with the drill press for the first one :) then i can remake them on the machine if need be :D

    Two points to keep in mind: Make sure the template is thick enough to fully locate the end of the bit before it hits the ally. Also, if you haven't laser cut MDF before and you're planning on doing it yourself, you should know the fumes and smoke are bloody awful - have plenty of ventilation. I didn't know this and caused an evacuation of the hackerspace :lol:

    lol!! I'm thinking of just using my laser engraver to cut some paper out to scale. Then just stick that onto al as a guide and drill everything on the press.

    But the smell of laser cut parts I think is wonderful!

    Thanks, I own a laser cutter and have so thats no issue there, run an activated carbon filter and ventilation to try to be a nice neighbour hehe :D

    So unfortunately this project is going to be postponed indefinitely...

    I was given a bit of an old-school "broken" CNC 3040 mill today, ended up only having a broken plug for one of the end-stops and was using a Parallel driver and the e-stop button had disconnected inside.

    I ended up sticking the GRBL Arduino shield I had ready for this mill and hooked the steppers up to that and it works perfectly...so can't justify making another CNC mill at the moment :(
