Help optimizing simply toolpath. Project is pecking instead of cutting smooth.

Curious what my issue is here. Using a project toolpath, and when cutting the oval you can see it's pecking in many areas rather than just running a smooth oval. Is this a factor of the SVG file it's using not being smooth, or something else?

 

Thanks!

Kind of hard to diagnose the issue when we can only see a picture, we have no idea what settings you are using. For better help, please attach your file.

Attached. Thanks!

If I had to guess, i would suspect it is because of these overlapping lines in the oval:

Perhaps try to modify your sketch by trimming the overlapping sections or delete the oval part of the sketch and draw a new oval.

Pretty nasty sketch you're trying to use! I guess a conversion from a picture, can you share the picture you used to create the sketch. Also what software did you use to convert to a sketch?

I used Adobe Illustrator and Image Trace. It was a large 2600px file, so figured it would have done better, but I guess I should inspect it closer in the future. https://commons.wikimedia.org/wiki/File:Ford_1927-1957_Logo.svghttps://commons.wikimedia.org/wiki/Fi...

Is the attached file any help? I added a sketch with a smoother conversion.

Waaaay smoother! What did you do to  clean it up so I can do that next time?

Message 10 of 15

I used a different program to convert the image on the page you linked. For the file attached before I used an addin in Rhino3d to create a DXF.

 

I've attached a SVG file to this post I did using inkscape that looks pretty good as well. Here's a link to a tutorial on doing this in inkscape.

@longshotsystems If you work with imported SVGs you might find this video useful for scaling to the correct size.

Between the SVG and DXF formats to import line-art is there a preferred/higher quality option?

Message 13 of 15

DXF probably has a higher accuracy but it will depend on the quality of the conversion. All really depends on what program creates the DXF\SVG.

I'll have to check out inkscape and also look into Illustrator more to see if there are ways to refine the conversion more. Cheers!

This might be the problem. Using an image that's too big then shrinking after conversion might be picking up too much detail. I only used the 800x446 image
