    painting machine

    Hi all,
    Recently solicited to take part to this cnc community, I would like to show you the machine I built. It is basically a router with a rotating head and four brush-tipped syringes that are lowered by a Z-axis. Please see attached pictures and follow the link below to see a short video of the machine at work:

    I will appreciate any comment/suggestion ...
    Thank you.
    Andreas

    That's very impressive! Is the rotating head commercial or did you design and build this yourself?

    painting machine

    I personally devised and built the painting head mostly by trial and error. To change any of the four colors I just give the right angular G-code to the step motor and it turns 90/180/270/360 degrees, then to make the syringe go down I give an M3 command to the motor pushing the piston low. Consider that control and timing is accomplished with a microprocessor. See picture for more details.
    The whole thing is still work in progress and improvements are on the way.
    I want to get to the point of selling my art work.

    Thats a CRAZY and COOL creation!!!! I like it!!!

    What kind of inches per minute was it running at in the video? Looked very fast.

    The video was accelerated at times, but the machine paints at 2500mm/min(about 100 inches/min) and does rapids at 7500mm/min. I tried to make it paint faster but it gets too jerky and the painting loses fidelity.

    This reminds me of the crazy wheel driven gantry with a spray gun someone started to build. I don't remember who though...

    andreas2,

    Good job on your machine.

    I thought about doing something like you have.

    Keep up the good work!

    For everyone who has produced a product, alot of others will have roughly the same idea. I described this to my wife last month while we were working on some business ideas.

    Good job!

    Thank you Switcher and Svenakela!
    Interesting what you found... I imagine the fun of having a machine like the one of VacPress (with my painting head instead) moving around my studio doing art on the floor!

    Hi Skip,

    Thanks for your appreciation. I am building a new painting machine that works vertically on a wall, so it will be larger (about 70" by 80") and more fit for art exhibitions. When it is ready I will notify this community with photos and videos.
    Cheers!

    painting tips

    I use the synthetic hair of paint brushes and the color is slowly but continuously sqeezed down from the syringe by the piston and motor+screw (see the picture of the painting head).
    Hey, do you want to build another painting machine?
