If you are concerned with your computer (desktop) not having a parallel port, one can be purchased and inserted into a PCI slot on the motherboard. The USB interface board that we sell can only be used with the Planet-cnc control software. The parallel breakout board is compatible to a wide variety of software control packages. Planet-CNC is compatible with our electronic combo's that included our USB Breakout Board. Mach 3 is compatible with our electronic combo's that include the Parallel Breakout Board. I get a "unhandled exception" error message. ThanksĬlick the link to add information to this solution: I had to wipe my computer due to virus and now can not download the USB software again. Will run through the calibrations again today. At first it won't operate my CNC until I read on Planet-CNC forum about loading the drivers on windows 8. Customer Response: I've given up on the wiped laptop and loaded the program on a different computer using windows 8. Unhandled exception issue may be associated with graphics hardware and compatibility. If you upgraded the Windows version, check to make sure your graphics hardware is compatible with the new version of Windows. Make sure that your graphics hardware works in other programs as well. Check to make sure all of the drivers are current for your graphics hardware. Also, make sure that you completely update your version of windows. I would remove any files that could be associated with the program, like setting files, or even register configurations associated with that software. Most likely, this exception is caused by some limit that is being exceeded (or the other way around). An unhandled exception generally means that, in the program code, the program is not checking against every possible exception that could occur.
