My last entry was about the trials of setting up and running my first big project on a CNC machine. Since then, I’ve been able to get back at it and make some of the necessary changes. First thing to acknowledge is that this was my first time extracting vectors from an image (my wife’s logo). When I first did that, I should have checked the vector for any imperfections, but I skipped that step and went straight to the toolpath setup. Heres a look at what the program interface looked like:

At this distance, it looks like it was a pretty good trace, but then I zoomed in quite a bit and noticed some pixelation in my original image file:

Because it was hard to see the outline, I deleted the photo from behind the vector in order to get better clarity. This shows that there were, in fact, erroneous nodes in my path.

I had to do a little research to figure out what controls would allow me to edit/delete the nodes, and was able to go over the entire path and fix it up… A process that took much longer than I would like to admit.

After highlighting, deleting, and fixing a bunch of nodes along the path, I was able to get a reliable vector. I deleted the “toes” and decided it was easier to draw circles, then merge them with the original path. The end result was much better:

Crazy how such small details can make or break a project like it did. Thanks for looking and playing along!

Tooch, I don’t understand entirely how these things work but I love what they can do. I can see a big improvement in the clarity. Keep at it, you’re getting to be a pro.
