Z is unpredictable.
I'm just testing/learning this new system (Omega 6.5 on Win 10). I opened an EPS with a simple arc path about 31.5" chord and 35" radius. I can make the router follow the path but it doesn't get the depth right. I did table init and material init. I set the material depth at 1.625 (chunk of wood) and .030 for depth and same for per pass. Yet, the router plunges about 1/2 inch into the wood. Ideas?
