Struggling with half tone

Hi, I was able to convert an image into half tone svg format but couldn’t execute it on my Shapeoko XXL (Inkscape and Illustrator). After several weekends of searching for a solution online, from what I understand, I may need to download some kind of software. I tried one from http://jasondorie.com/page_cnc.html but didn’t work on my mac. Can somebody point me in the right direction so I can get this amazing portrait printed? Million thanks!! PS I’ll post my progress on here too.
