By the by, I just found this.

Still doesn't really explain distance tolerance.

My understanding of CV distance tolerance, is that it controls when the machine goes from CV to exact stop mode based on # of units. Units being described as, step resolution. While testing different settings, I found what works for my machine. Also during those test I played with the plasma mode. It was very interesting what it does. I had some code that was point based in 2.5D. When running in CV only, it was very jerky. When in plasma mode it was more like a metered flow in all axis.

Just my understanding of it and observations. :)

That did the trick perfectly, I set it to look ahead 200 steps and it ran without a hitch. As a result I felt confident to run a test on a body and neck design using some 1/2" plywood that was sitting around. Not only did it do a nice job, after measuring it to verify consistency with the blueprints I found that it was dead on down to the last 0.001" and had a fantastic friction fit in the neck joint. I now feel confident to move forward with the first complete guitar to be cut with this machine. Here are a couple of pictures of how it turned out:

In case the neck looks a tad wide, that's because it is. When built, this guitar will have 8-strings. Part of the reason it's being delayed is that I am just getting started building a CNC pickup winder and active control circuit that will likely outperform the EMG 808's that the client has requested.
