Hey Zax, got another question. Haven't been able to screw with the firmware & arduinos for a while, life got in the way. I do have a new oddity. Now, on the core-xy machine any time I bring up the laser control screen it auto sets current position to x:0, y:15, z:0. It used to set all three to 0, so obviously something happened along the way, but I can't figure out what. How do I set this back so it auto sets current position to 0:0:0? This has screwed me up several times because I started the engraving where it was at and Y was off by 15...
