The screenshot below doesn't look like much but represents way too much work.
I recently finished my probe. Here's a shot of it mounted on the router
After getting the probe to work. I ran gridprobe.ngc from the example files that come with emc2. The file can be edited to control the range of the scan and the size of each incremental step. I set up the file to probe the surface of the router at 1 inch increments in both the X and Y direction. The output of the scan is a list of XYZ coordinates in an ASCII file.
This Guy has a couple scripts for blender that are very handy. One imports a CSV file and the other 'skins' the resulting point cloud by creating faces for the vertices.
The output from the scan had to be edited into a CSV but that was easy. After experimenting with the settings for the skinning script I had a mesh which I exported to an .STL file and brought into HeeksCAD. Voila. A perfect scan of an almost flat surface.
Next up: Try it with something more interesting.
I've gotten so comfortable designing in qcad that it's my default tool for new projects. But qcad is 2d only. So lately I've been forcing myself to use HeeksCAD more. I still find the UI to be a bit clunky but I'm getting better at it. I'd love to see some quick tool bars for things like snapping and selection.
I'm going to build a touch probe so I can play with some of the other HeeksCNC operations. Here's the design I drew in HeeksCAD based on this page
