Hello, I am somewhat new to CNC and I am probably trying to run before learning to walk. I have a home-built 4 axis router table which I have been using for a little while now. I have the 2010 screen set and I have added the laser crosshair xy zero and a z axis zero plate. Now I want to learn all that I can about digitizing. I made the probe and I kinda have it working. I have been trying to use it with the 4th axis digitize wizard. One problem I noticed is it occasionally does a arbitrary point without actually touching. I put a stiffer spring inside the probe, thinking git was from vibration. But it still does it. I also noticed that when this happens it doesn't light up the probe led on the screen like it does when it actually touches. I am sharing port 13 between the tool zero plate and the touch probe(inverting the signal when needed.) Any ideas what's wrong? I would also like some idea on how to work with the resulting point clouds. I would like to be able to take something I turned on my wood lathe, probe the surface on my 4th axis, then convert the point cloud to something I could work with to cut and decorate the surface of the wood turning. Any help you all could offer is greatly appreciated.
