Guys, I'm almost building my CNC. I came up with a question. Say I have a complex geometry that needs to have some drawings on top. Assuming I have the slt drawing of this figure.
This geometry may be flat surfaces, curved, etc. .. If I wanted to just write or draw little lines on the surface .. the CAM software can do this?
In other words, I have as input the complex geometry and the lines need to be drawn on the surface (if I can do engraving on the surface where I need to pass the drill).
In the end, cnc machine would just go the route of the line on the surface (being any type of surface: regular, irregular, etc).
I saw the videos on youtube, usually the part to be machined is a rectangle or a general surface. In the CAM software I can insert my custom initial geometry?
Look for example this computer mouse, I would insert the STL model of the mouse as initial geometry (which will be machined) and the STL model of the mouse --->already machined<---. Finall, the CAM software would generate just the drawing on the picture (the skull **)
Can CAM softwares do it (just engraving on the general surface)?

If yes, Can you tell me some softwares for that?

Some CAM software can project the drawing onto the curved surface. Vectric's Aspire can do this.

I think many softwares will do that, a google search of "project toolpath" shows mastercam, aspire, surfcam, artcam, etc..

How do you know your model matches reality though?

I think the best option is probing the surface to be machined in the CNC control, then transforming the toolpath onto the probed surface.
I have used probekins in linuxcnc to do this. I think another software is "Warpdriver" though I have never used it. another is "Autoleveller"

Ger21, Vectric can do this to curved surfaces? irregular?

in other words, would like to follow a path of a cnc robot welding .... using a cnc to follow a path... https://www.youtube.com/watch?v=HUU3HdxOqZs
