I have successfully engraved a few jobs in the past ( maybe FC 0.19 or 0.20 ). Although it was inordinately complicated, I found a few videos which gave a working method, but now I try to do it on master the goal posts have moved once again.
I tried opening an old project which had worked but the tree seems borked with lots of things out of place. I guess that non backwards compatible changes to FC how borked what was a working file.
could someone outline the process or point to a guide or video which explains what is needed.
These are the first two pinned topics in the Path/CAM sub-forum, which makes it a lot easier to find if you are like me and keep forgetting the keywords to find these!
Thanks. My main problem was not being able to get a path on a ShapeString. I was forgetting the fixer, though last time I used it totally trashed the file anyway.
I did manage to get the path. For reference, this is what I did.
Made rectangular block in Part Design.
In Draft WB I selected the top face with Utilities | Select Plane.
Then created the shapeString.
Flip back to PD WB and created a pocket from the face with the text on it.
Flip to Path WB, new job , add v-shaped tool.
create a deburr path on the main face of the block now hollowed out text.
Reduce W,H of the deburr to nominal small values like 0.1 mm ( could be 10um for precision ).
This gets a path which follows the outline of the text.
On the CNC , I lie about z-0 to get the depth of cut I want on that line.
