This also occurs in Carveco Maker. If you setup a v bit to a profile it will carve each individual line and screw up the detail. Don’t have an answer for but hoping it will start some conversation on the the topic. It is very frustrating.
When I started with a laser burner… I went through exactly what you are going through, and likely many others have and will have the issue. I looked again once I started using my OF last year.
It honestly sounds like something that should be really simple… lol
I found an old thread about an Inkscape add in that did a centerline trace, it did not work well. I found it buried in github somewhere.
What I ended up using adobe illustrator to manually trace and then node editing to “perfect”. It’s worked the best for me. I could then make my manual trace a path.
I tried in inkscape but I was more familiar with illustrator.
Yes, it is a PITA learning curve no matter which way you go.
But there are lots of you tube videos to follow.
I’m really hoping someone chimes in with a better method (shortcut). I tried all the online centerline tracers I could find none worked well for me.
I struggled with this as well. What I eventually learned is that to V-carve variable-width lines, you have to use Fusion 360’s 2D/Engrave toolpath, rather than the 2D/Trace toolpath. Using the Engrave toolpath, I got nice V-carvings.
However, the Engrave toolpath works properly only on flat surfaces. I wanted to use it on a gently curved surface, but no dice. My workaround was to inset a flat “inscription area” in the curved surface.
