Hi all. New to community but not new to machining. I have run (maintain, program & operate) Mazak lathes for ~15 years. I have been graciously given a Haas lathe from the powers that be. I have been messing around with it for around 4 months and keep having the same issue with the VPS. When using VPS putting a OD GROOVE, with a radius or chamfer, the VPS system does not complete the feature correctly. I end up with dual, square corners. I am using a .125" wide groove/turn tool. Any thoughts or tip would be greatly appreciated. This is not the only issue I have with the VPS system. Below is the output code for the OD GROOVE cycle, that the controller is generating;

I am going to the Haas training center in 2 weeks and will ask the same questions. Until then I'm going to try to only use the Haas lathe for show and tell. My 20+ old Mazak QT250 outperforms in almost every aspect and doesn't fight back so damn much.
