Anyone interested in V-Engraving?

Yes! Nice work.

Great, indeed. Do you calculate the middle of the characters?

I'm using openvoronoi, (another library from the same guy that brought us opencamlib) to generate the medial line path. It should work for pretty much any font.

Openvoronoi has the potential to do a lot of really interesting things. It needs more exploration.

Awesome! If I can do v-carving, and text around a radius on freecad my workflow would become all freecad for my needs. Thankyou for your videos and work Sliptonic!

Have a look at Macro Circular Text. You can install the macro to FreeCAD from Tools > Addon manager > Macros.

You should be all set. Welcome to the forum. If you need help with the macro or anything else, please ask in the help section of the forum. Oh, and read the directions there before posting, it helps in many ways.

My code is in a branch on my repo:
https://github.com/sliptonic/FreeCAD/tr ... ure/vcarve

This will require installing OpenVoronoi which might be challenging. I don't think it's fully converted to Py3 yet.

Ok. Thanks for the info...

Hmm, will see what i can do...
But V-Carving has a high interest i think

Cool stuffs
Those days I was thinking about all developments concerning PathWB and features like this one, I mean features which use only G01 linear interpolation and segmentation instead of G02 or G03.
I want not hijack this thread, but I would say this kind of strategy is pretty suitable with raspberry Pi cnc limited skills.
As you certainly know Raspberry Pi are usually not suitable with cnc works. Usual strategy is: Raspberry -> gcode sender -
> Arduino -> cnc machine.
RPI 3 doesn't handle itself more than 5-10kz of pulse rate with Linux cnc and preempt rt kernel.
But recently some development which are achieving by pantadeusz seems pretty interesting:
https://github.com/pantadeusz/raspigcd2
With his code it seems he reachs more than 18kz pulses, furthermore do this way could allow to handle fast watchdog for pause or scheduled stop. His code handle only G0 and G01, so it could be suitable with some features of Freecad path WB
That's all, just for sharing information. I hope I'm clear enough with my rough English.
I guess mlampert has some interest about RPI, so:

ping

See you,
Alex
