Incomplete shape in KrabzCAM?

CAD/CAM Software Tips
1

As a first project I’m building a router lift for the router wing in my tablesaw. First step: Mounting plate.

I’ve drawn the plate in FreeCAD, exported to SVG, and then bring it into KrabsCAM. I can path the circles in the middle but I can’t get a path for the outside. I suspect the outside shape isn’t being seen a closed line. I created it by filleting a rectangle in FreeCAD. When I select it in KrabsCAM I can select the whole thing with one click.

Does my theory make sense? Is there anyway I can fix this at either the CAD stage or in KrabsCAM?

Why don’t you use the CAM module of FreeCAD to do this?
It’s working perfectly for all my Maslow projects.

Didn’t realize it existed (I have a whole hour experience with FreeCAD :grinning_face:) I used to be pretty good with AutoCAD but that was 15 years ago and my employer was paying for it. I’ll take a look, it would be nice to have an all in one tool.

Hi, if you select the outside path only, you will see some describing text on the top of the screen.
If it says closed=false, then the path is open and you cannot use it as basis for a profile toolpath.

I guess this can quite easily be fixed in inkscape (or some other tool) with

btw. It’s also possible to create rounded rectangles in KrabzCAM with normal scaling.

  1. create square with ‘4’
  2. scale in x/y direction to requested x/y ratio
  3. normal-scale with Shift-S

, … I guess it all depends on your workflow.

Hope this is useful

Several of the CAM programs I use have different colors, or perhaps solid vs interrupted (dashed) lines for closed and unclosed shapes. I do a lot of v-carving on non-Maslow machines, and with Vectric’s VCarve independent closed shapes are both a requirement and a royal pain in the fundament
