Airbrush painting, not really about painting. OT

Tell me what you need for the air end of your project. I have lots of plastic air hose, fittings, 12/24volt valves, etc.,etc.. I'll send it to you. This is all top quality from Festo here in Germany. Although I still think a monkey would work fine.

Thanks for the kind offer but today I found a coffee dispensing machine that is waiting to find its way to my workshop!

Project paused while I look for a compact solenoid valve to control air flow, I might even have to make one!

We do not have many sheep now as dairy cows have over-run our green pastures...

So old fashioned! My way is much better! Good luck with this project. I am keeping a watchful eye on this thread. My neighbor makes a lot of signs.

You could take a baby lamb, dip in paint, Zip tie to the Z axis and have at it. Or a trained monkey. Poke him with a stick when it is time to dip the brush again until he gets the hang of it.

I only come here for these good ideas!

Sorry but you gave me so much crap when I was building my sheep shearing machine that a little pay back is in order!

A picture, just for you 'Mr Forest'....

I have an Arduino dedicated to the control of the airbrush, initially it will control paint quantity (needle) only. This Arduino will have a manual input so that I can 'tune' for best paint quantity.

Paint ON/OFF will be controlled by Z axis.

Air control will be manual.

I need a method for the airbrush Arduino to eavesdrop on the GCode stream to the GRBL Arduino, there are a few ideas but yet to be tested.

Please refer to post #6. There is this I found on-line....

I had watched the video this screenshot is from before you made this post and thought what he was getting for lines was more than reasonable for a 4’x8’ sign, probably much smaller as well.

Without seeing what your current signs are like, if the airbrush works out, how far on programming do you plan on going with height and paint flow control to get different effects like what was in that vid?

Pens, yes all very interesting but as I mentioned in the opening post I have been there and done that.

The ones in the Link posted above can be had empty, just use the paint or ink you want. Its as simple as touching it to the surface and using as a plotter pen. No interfaces to mess with and of course any width you want. When I get some of my other projects done I will try on my setup.

One advantage of the airbrush is the ability to use any reasonable paint. The plotter pens use what they use for ink, you do not get a choice. That normally needs no particular resistance to weather or sunlight. Paints can be had of any type, with resistance to those and other environments.

When I had my large CNC as opposed to the one I have now, it was 4x4 feet. I made a holder with slight spring action to hold HP plotter pens and it worked great. Same idea could be used for those markers in the Link above.

My post did quote your post #6, all I'm pointing out is that you will not
get a sharp line that a brush or pen will give you, if that's what you're after.
The picture you found online the lines look soft to me because it's sprayed.

It may be that the results will not be good enough to use.
