Path workbench. Can't create route for single face

Post by Foxhound »

I'm using KiCad for making routes for my CNC.
I try to cut workpiece from one side. Like at the picture below
The problem is that then I create Profile job using only one face from my model, I got error:

Code: Select all

<Path.Area> Area.cpp(1317): project failed
<Path.Area> Area.cpp(1459): empty projection
PathProfile.ERROR: Unable to create path for face(s).
list index out of range
How I can fix this?

Setting correct values for final depth (and stepdown) works excellent in 0.21. I'm not sure if a profiling single line works already in 0.20.

And what is the correct depth and stepdown?
You select edge or face to create profile operation?

@Foxhound Why don't you use a bit of left field thinking and use another solid as I would call a DummyHelper. This was created in 0.20 just to be clear, see attached.

I can't get this to work with my current version. Will retry with an older one later.

Here we go now (I had selected the lower line and that always works on the wrong side).

- Edit your Profile operation
- clear the base geometry and add the upper edge:

- set FinalDepth to 0
- set StartDepth and FinalDepth to the same value for a single path.
- confirm.

I managed
I select top edge
Then change start depth to 2, final depth to 0, and step down to 0,5
It's workin for me in 20.1 and 21.0
