We have:

Halftone generator on Cutrocket

This was announced/demoed in a limited way a while back — had occasion to reference it in a support ticket recently, so here’s the text from that: We have a halftone generator which will accept black and white images, so you will need to convert any image into a black and white picture. That is the only type of picture the generator will accept. Help file: https://cutrocket.com/halftonehelp.php

Thanks Will that looks like it will work for me,have one problem,I am still on 2009 I Mac and I am running out of memory and can not get a detail finish.Looks like I am up for a Mac book

[WillAdams (William Adams (Carbide 3D))]

Might be able to just adjust your settings.

Let us know at support@carbide3d.com what settings aren’t working and send the image in and we’ll do our best to look into this w/ you.

Hi Will everything seems to work except I run out of memory,what is the lowest number I can use for grid density if I had a suitable computer?I can get down to 3 and that’s when I hit trouble.

Post the file or send it in to support@carbide3d.com ?

@Graham Check out RasterCarve . It’s free and open source.

[Graham (Graham Murray)]

Hi Will,this is only a trial photo in black and white I am trying to get a finer detail in halftone,can not get the numbers down low enough to make it useable,it has to be the 2009 I Mac

[Graham (Graham Murray)]

Hi Neil,tried to open but apple is giving me big warning signs about it,also saying licensing is out of date

After 13 years, I think your Mac is ready for retirement.

[Graham (Graham Murray)]

You are not wrong,in NZ we have been trying since beginning of February to get an I Pad,out of stock,I will see what happens on Tuesday for the apple event to see what Mac books are coming out

[neilferreri (Neil Ferreri Ω)]

I see that too, excited a couple of weeks ago. I submitted an issue on GitHub.
If you’re comfortable with the command line, you can run it that was as well.

EDIT: Should be fixed. @Graham Try again. https://rastercarve.live/

@graham sorry about the issue you are having, but that there us a NICE looking Golden Retriever you have there.

[Graham (Graham Murray)]

Hi Gary,we have photos of golden retrievers I want to put on acrylic but for a trial went out and took a black and white of one of our Llamas

[Tail-wagging-the-dog (Gary Hazel)]

Just poking fun as my favorite dogs are Golden Retrievers and Labradore Retrievers. lost the little guy in my avitar a short time ago.

[Graham (Graham Murray)]

Hi Gary,that’s not very good,we have had 3 Golden Retrievers one after the other,they are great dogs,hence wanting to set them in Acrylic LED

[Graham (Graham Murray)]

Hi Neil,yes we are working,now need to try on some scrap whatever

[Graham (Graham Murray)]

Hi Neil,have you produced any projects from Raster Carve and how was the quality??

[neilferreri (Neil Ferreri Ω)]

Just a test I did a couple years ago…just playing around.

@neilferreri

This was a test I did with a picture of my sons.
White PVC, spray painted black.
