Hi, i'm new here, and i was milling today when i encountered "runtime error 9 - subscript out of range". I am cutting 3/4" mdf, and pathed on mastercam X. The mastercam file previews perfectly on mastercam, and the exported NC files preview perfectly on the Techno CNC interface as well. I am able to preprocess and preview it on the Techno CNC interface. However, once i click on the start button, i get the error and the interface crashes. These are simple contour cuts and pocket cuts. Will someone please help me??? Thanks!
