Brains Development / is there an"OR" in brains?
« on: March 18, 2014, 08:39:12 PM »
Hello,

I am just starting to play around with brains.  I am wanting know how to do a logical OR.  For example when Input1 OR Input2 are active, do this....   Essentially I want to know if I can use it to make 2 inputs do the same function.

Is this possible?

General Mach Discussion / 4th axis 3D model surface cutter path
« on: March 30, 2013, 06:59:02 PM »
Hello I am a woodturner who is looking for a way to make cutter paths to cut designs on the surface of my turnings.  I can probe the surface and create a point cloud.  I can take the point cloud and create a 3D stl file. My question is how can I generate cutter paths to cut designs on the surface?  What software would I use?  I know Aspire can import a 3D model and cut it, but I don`t think it will make cutter paths to modify the surface. I don't mind wrapped rotary. And suggestions are greatly appreciated....

General Mach Discussion / Help with digitizing/probing
« on: March 21, 2013, 08:36:05 PM »
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.
