  • Marc,

    In those quotes, they are both imperial.

    You need for them to quote you on metric size. 1″ is 25.4mm, so that is too large in diameter. The 3/4″ would be much too small.

    They need to quote you 25.00mm OD Tube and 1.5mm wall. The 1200mm would only be approx 1 foot longer then what I’m working with, so it should be fine with that wall…[Read more]

  • Hi tortfeaser, I see a Sydney phone number, which part of Sydney are you in.

    I went with the Stainless Steel 25mm OD tube, and found it to be very accurate along it’s length. The wall was 1.3mm and over the length of 875mm, I have no deflections.

    The stainless is very expensive though, and I think If I built another MPCNC I would go the…[Read more]

  • The second video does appear to be smoother in operation, but. You need to tighten those belts up. If your X and Y axis are not running perpendicular to each other and/or not parallel to the side rails. This should only effect the job, not cause the jittering that is being transmitted down the belts.

    Have you tested the driver output voltage for…[Read more]

    WOW….that is cutting like it was Balsa Wood, you gotta be happy with that!

  • Maybe the method is not new but the idea and solution of this 3D printer is great.

    I was looking for a small, very accurate 3D printer and found this about 2 months ago.
    I registered to be given heads up on when this was live, and available to purchase.
    This morning I got up at 4am to place my pledge, and I was not disappointed. I ordered

    Is that 3 Ply? You cut that in a single depth cut, wow!

    Very nice work.

    Happy anniversary Ryan, well done.

    I started with this project in July last year, and completed the build around late September 2015.

    So the first build is about 6 months old, still love it.

    Cheers

  • For me I do not see a pen retaining issue. I say this because I see two circles, both of which are very similar.

    If the pen or marker was not being held steady the lines drawn would be more jagged, and the finished circles would be very different.

    I do see an out of square gantry, as you have indicated with your X and + description. Have a look…[Read more]

    Hi Fernando,

    I used cable ties, simple, cheap and works a treat!

    I designed the little end stop and cable chain tower myself. I have not put it up
    as I did not think anyone would be interested. But I will look into getting it uploaded
    and a link posted here.

    Cheers

  • Hi Jon,

    I print in ABS, there is a product here in Australia called Tarzans Grip, works fine for me.

    But I have not glued any parts together on my build. I used an M4 bolt and nyloc nut to assembly those parts!

    The only reason I see for using any glue would be prevent the parts for turn, on themselves. But only a very little bit of glue would…[Read more]

  • Gianluca,

    My thoughts are that if you print in ABS and the result was what you showed in the images, all should be fine.

    ABS requires higher temps to build so there is more shrinkage then PLA.

    If your prints are with PLA, you may see if you could tweak it a little. But to be honest I think your prints are fine
    and the more you worry about…[Read more]

  • Hi Gianluca,

    When I measure a square block such as the one your have, close the vernier jaws along the entire surface, from corner to corner.

    That way you see any undulations and a more actuate measure.

    By the way I would suggest your second photo measures about 19.85mm but without seeing all the digits, not sure. Except to say that it is not…[Read more]

  • My take on what I have read!

    The movement you have shown in all three videos, I would expect if the steppers were not energized!
    So that side of it all looks good to me.

    The oval shape that you seem to be achieving, I suspect it is caused by the fact that your “better Z middle” is slightly longer then it should be.
    By longer, I mean that your X…[Read more]
