Messing around with halftone carving

[JeremySimmons]

Finally got around to making mine!

Halftoner win

24x29inch mdf, flat black spray paint. 60degree vbit 3-4 hours. One really important lesson learned. Make your background black so you can place all the dots on the subject. This one has 8500 dots on it. For anyone interested in using Halftoner to do this, Easel isn't currently compatible with the GCode halftoner outputs. I'm working with @JasonDorie on a patch to address that. If you want instructions on editing the GCode now, shoot me a message. I'll do a post soon on that, and have a new …

Never posted mine ...

What materials/ paint method did you use?

[FatKatOne]

Heres my shot at a halftone picture, I think it came out awesome found a source of cheap canvas's as well, my local Home depot sells 24"x24"x1/4" MDF panels for around 5$

I have been experimenting on white foam-core board that I spray paint black.
I will show results when the experimentation is done.
Still trying to figure optimum settings.

I REEAAAALLLYY LIKE HALFTONER APP!!!
This one is done without the offset.

Thought I might add a helpful tip for those using MDF and don't necessarily want the natural mdf color for the dots. I normally will cut before I paint. I will then paint the whole board the desired color for the dots, then take a very fine foam roller and very lightly paint the background color on. By lightly I mean very light pressure with very little paint on the roller. It takes a little practice, but will greatly improve the look of your projects. Hope this is helpful!

Yea I have thought about ways to do this, but I have done very fine holes that will fill in I'm
Thinking about trying this translucent spray paint I saw at the craft store as long as the base coat is dark it should only color the "holes"

[NicholasFortosis]

I was able to get it to work on relatively fine/small holes too

I wonder how well it would come out on pre-painted colored MDF like this:

Yellow MDF Sheet

[FatKatOne]

Would be awesome but the price is high on that mdf

[FatKatOne]

The top layer is easy to paint before cutting , I wish I could color the inside of the mdf, I'm working on a few ideas on how to do that I'll post pics when I get a good solution.

[LanceRose]

Wow, your like a mystic or something. I had the exact same effect. I will be fixing my set screw and trying again!

[RickPeterson]

These make me dizzy...

[LanceRose]

All good. I also upped my pot on the Y axis. now it is working like a charm I have done 3 of these this week and they look great.

1st time I tried the lines it wigged out on me. I wonder now that I am 'set up' if the lines will work better? Guess we will find out.

Thanks for all the help.

This is my first stab at half toning using lines instead of dots. Initially I had issues with the Universal GCode sender, where it would not scale correctly. It was cutting the entire picture in a 3inch rectangle. I downloaded the Platform version and it resolved the issue.

Jason's tool will be keeping me busy for many weekends. I love the magic of this.

BTW, I used plywood that was painted black, and then cut.

[FatKatOne]

I actually have an order for 3, 24"x24" "halftone posters"

[FatKatOne]

do you mind sharing your halftoner settings for that image?

[DanielBrice]

I think I used 3mm spacing and 3mm max width. Used the setting to cut each line twice as well. It cleaned it up a lot and left no feathers.

Thanks!
