My machine is a Shopmaster combination Lathe/Mill. Had to change out the computer a few days ago and upgraded from Windows XP to a computer with Windows 10. You guys helped me get the proper driver for my UC100 adapter which allowed the Mill portion of Mach3 to work well. However, the 'Turn' (Lathe) portion bombs during the loading process. From previous posts, I learned to use the edition of Mach3 which corrects of Windows 10 problems (ends in '62'). I can try deleting all my work, reloading Mach3, and see if this helps but it sure would be nice if there is a simpler solution. I've tried shutting down the computer and rebooting a number times. When the program bombs, a light blue Windows screen comes up and which tells me it is rebooting Windows. Thanks for the help so far.
