Klipper and linux

hello, im having trouble getting my printer configured. i tried using the printer.cfg that came with the sv07 but i get nothing but error after error. after correcting a handful of errors i ran into error for the virtual pins and i haven’t got a clue how those work. also, in the original printer.cfg there are lines that are. commented out, why do i get a error for the commented out lines on linux but the klipper screen. thanks
