I recently purchased a new cnc router and it came with Mach3, so I installed it and everything works from main screen, but I am unable to load all the other screens (mdi, offsets, etc.). The other screens are in Millbitmaps, but when I try to load them, the only options are for files with .set ext. and bitmaps are .bmp. The main screen file is in 1024.set. Any ideas would be appreciated. Thanks
