Here is a new post for build 769 in the NEW format for Milltronics Centurion 6 Vertical Mills. This post 'may' also work (and should) on the Centurion 7, but I can't test that. I have run this post on 2 different Centurion 6 machines and works well.
Note however that Machine Cutter Comp left/right/comp off (G41/G42/G40) have been replaced with Centurion 6 Auto Comp left/right/off (G45/G46/G47). These can be changed back at lines #11-13 and it also states this in file. Could not test all the 4th axis parts of post, but they should also work.
This post has also been sent to the BobCAD team. Hope this helps someone out, gave me huge headache
