Does anyone know where I can find a good Mastercam post for a Prototrak SMX Mill. The one I have been using creates code that if I don't go in and edit the first Z-axis move it will rapid down to Z0 then back up to where I initially set the rapid position to. Also I'm having trouble with a program and I'm told to create it as a .GCD due to the Prototrak SMX can't understand the G18 that is in the program I created, but when I try and save it as a .GCD I get the following A error message saying it cannot locate .GCD in the control definitions. Any help would be gratefully accepted, Thanks, Dale
