First off I would like to say that building the PMCNC has got to be one of the best projects I’ve ever done. When I built my MPCNC I broke all of the rules, like building it too big. I have not run into any issues as yet but I also haven’t cut anything solid either. So far just foam. The video and photos show my cnc and how I cutout foam tool holders. I have yet been able to master relief cutting (any direction there would be appreciated) so these are just 2 plain cutouts. For the most part I’m very satisfied with the results. No more loose tools and no more misplacing tools only to find out later down the line.
Very nice! May need to give that a try once I get my Jackpot board installed on my Burly.
Giving up on the arduino? 
I love hearing that!
Nice job on that foam.
The only reason I had the Uno and CNC shield in the first place was that a vendor sent me the wrong thing, then didn’t need me to return it when he sent me the RAMPS kit I’d ordered. Looking forward to moving to a more modern controller.
