The company I work for has 3 Makino wire EDM machines. They previously used PEPS as thier CAM package for these machines. When I started with the company we were "upgraded" from PEPS to VISI by Vero (the company that now owns PEPS). After going through the VISI training and using the software for a while, we are having a lot of problems getting up to speed and producing the parts we need with VISI and are starting to look at other options. MasterCAM certainly is the fisrt that comes to mind. Looking to see what others have to say about MasterCAM and are there any other CAM packages that we should be looking at for wire EDM? We use Autodesk Inventor suite(AutoCAD and Inventor) as our CAD package if that makes a differance.
