I Have an Ox and a CNC Shield (with individual psu's for all the motors). But I have a hard time finding any good info about software for the Shield. It's also hard to find any info how to connect components to it such as limit-swithces and auto zero point etc. Almost all the tutorials use Mach 3. Is that still the best solution? And what is a good card supporting that? Or is grbl now more common and user friendly? I had to put the cnc-machine on ice for almost two years, so I'm totally out of the game at the moment.
