CNC or I know what you did last summer…

Well, this is what I did… my CNC machine… It has a cutting area of A3 times 10 cm in depth. The only drawbacks are that it is very noisy, produces lots of dust and it is really sloooooow…. So I am in the process of upgrading it with a holding case to reduce noise and dust and with new threaded rods that are supported on both ends, not just at the motor end as they were.

To the video and some links in this post I add now some pictures:

  • Raw materials
  • Imagen005

  • Basic frame built
  • Imagen002

  • Details of the motor / rod coupling
  • Imagen086

  • The finished monster
  • Imagen004

  • You can see the rod unsupported on the right, which I am extending now to the frame to hold it there with a bearing, so that I can reduce whipping and vibration, and hopefully increase speed

    Where choices need to be made…

    Eduard Punset states that the overwhelming availability of choices present in modern life is a hell of a stress factor and an important cause of unhappiness. Man, he is right!

    At the beginning of the DIY-Cintiq (I should really get a name for mine!), many choices need to be made, and they are difficult to deal with at times: I found a great offer on ebay for a wacom table, but quite a large one: 12”x18” for 50€ total, and I could not refuse it (I know there are far more offers in the US, but post and customs costs to Spain cause you to lose any possible gain). Also I got a very cheap compaq 15” monitor with external power supply for 40€… I got it because it is the only one I could find at surplus dealers with external power supply.

    Now I am sitting with a 12×18 tablet (well, still awaiting for it to arrive!), and a 15” monitor, half the size of the tablet (9”x12”)… and I face three possible options:

    1. Build with what I have: I would have half the tablet for the monitor, and the other half to map to the main screen… it seems nice, but maybe too big an not very practical. Also I need to check the jittering compatibility of these two !
    2. Search for a larger monitor that could fit better my current tablet… problems: cost and difficulty finding larger monitors with external power supply…
    3. Search for a smaller tablet and use my current monitor… uuuumh…
    4. Get both non-jittering monitor & tablet from a friendly guy at Bongofish…

    Choices…

    The bottom-line: read before you buy… this thread would have helped a lot. But to tell the truth, it is stupid why I get confused by measures given in inches instead of meters… why? They are just numbers, equally comparable… some strange wiring in my mind forces me to try to convert them to meters and compare there in an “unreal perfect ethereal world”, instead just compare 12 to 12 and 18 to 9… Punset might write a whole new book from this…

    “If you build it, he will come”…

    Ok, not the most literary quote here, but if it rings the bell, then we are aboard the same boat…

    So, who many times you think, “oh, it would be great if I could build a […], wouldn’t it?”. Just go and google it, chances are someone has already thought about it, and yes, surely built it too, and even have a nice forum set up full of wonderful people willing to share and help.

    Well, how about building a Wacom Cinquit

    The thing is a beauty, but just a bit pricey for just a whim… maybe Art & Design pros can afford it, but not me! I will do the googling for you, and the site to go is definitely Drew’s DIY Cinqit page… and his forums.

    Anyway, isn’t it too much of an effort just to get a tablet PC?… not quite, since Wacoms are much more functional than just a mere tablet: they are pressure sensitive among other wonders… In any case, it is a little overkill if you are not a pro in Arts… hell, I don’t even draw!… but you know what?, it seems so much fun to build one, and I am sure it makes a great present for someone who works in arts.

    So, here I go!… this is not a project for the faint hearted, though: we will be seeing the guts and most likely corpses of LCD monitors, pen tablets and the like… take out your weapons (let’s say s screwdriver and soldering iron) and let the game begin!

    In which a new adventure begins, not knowing where it will take us or how long will the journey last…

    As stated in the  about post, I will be including info on different projects I have  been doing and hope to keep doing in the next months.

    First one I want to include is a DIY CNC machine built from plans purchased from Rockcliff… here I post two videos of the first cuts… The model is scaled up from the original plans, which has caused some problems: the threaded rods that drive the motion are not supported in one of their ends, and this makes the rods bend a vibrate too much, so at this moment the machine is torn to pieces to upgrade it with supported rods, which will hopefully allow me to increase both, stability and speed. I am also planning on builing some kind of isolaion enclosure to reduce dust and noise, which are a no-no when you don’t have a workshop and use an spare room in your downtown flat.

    First video, just trying out the machine…

    Second video, trying the 3D carving capabilities:
