So I made a file on solid works for a les paul guitar, and the neck pocket needs to be at an exact angle for the guitar to work good. I have this angle in the solidworks file, but for some reason the cnc router (using Partworks 3D) I use doesn't consistently cut out this pocket correctly. A couple of days ago I tried it with a .5 inch bit with a pass depth of .5 inches, and that worked . The next day all I changed was the pass depth to .25 and it didn't work. it cut out the profile of the pocket but half of it was at ~.25 inches the the other half was at~.5 inches with no angle.

I was wondering if anyone had any ideas to why this is happening because I am completely stumped.

The first URL is the pocket that got messed up and the second one is the pocket that was done correctly.

Thanks,
