Nevermind.  After reading thru some unrelated posts. I figured it out.

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?

Hey Bob, thanks for asking. I think I have it figured out. I need to experiment a bit more this weekend.

Yeah i've seen that article. It's a great article. But it looks as though what I want to do is listed under "What It Won't Do."

So, when you did your "turnings", you had to machine the whole exterior?  Or did you approximate a design in VC, to make cutter paths for your hand turnings?

I have posted on the Vectric forum also, I started there, but no responses yet.

Bob can you tell me about how you were able to engrave your turnings?  That would be a good start.  Can you project the cutter path onto a contour and get a fairly even depth?

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....

TP you have given me food for thought.

All I really want to do is take it we ms that I turn on my wood lathe, probe them on my rotary axis, then design something that can be cut on the surface.  As Gerry mentioned I can use a single line of points for this, once I figure out how.

It would be nice if there was a program that could convert raw data points from angular to Cartesian and/or vise versa.

How would I convert from angular to Cartesian?

I am not sure what relationship I am looking for. I just thought that a 4th axis digitize wizard would somehow mathematically calculate points such that the resulting point cloud would resemble a 3d object, round or otherwise. Because this object is round, I end up with duplicate sets of points for every rotation.  I guess I thought that there would be a way to calculate Y points based on degrees of rotation. How would I use a point cloud with only X and Z values for a three dimensional object?

I understand what you are saying about probing one line along a single axis, and i plan on trying that if I can find a wizard that will let me.

After reading different areas on this forum, I realized that I have never done the Windows XP Optimization and I had a bunch of startup processes running. After killing all of the unneeded processes I was able to run Art's 4th Axis Digitizing Wizard without a single error (hopefully not just a coincidence.) Now I have new questions:

The resulting file is a triplet text file with CSV data. I probed a round piece on my A axis using center of workpiece as Z zero. What I get are X, Y, and Z values that are all positive. How would that relate to a three dimensional round object?  Also, if I open the file in MachCloud, I don't see anything?  Are there any instructions for MachCloud or any of the wizards?
