Has anyone setup a Shapeoko 3 XXL?

Trying to get it setup correctly. Using GRBL. Can’t get the Positioning to work properly. Jog works OK, but when i attempt to move to a specific X,Y location, the head goes to X0, Y0. When I Home it, it goes to X=-3, Y=-3 (which is the correct location). Also, trying to understand the machine “Home” location which is Upper Right-hand corner (-3,-3) and where the material Home would be, which is about -800, -800. How do I get the axis coordinates flipped so the coordiantes aren’t negative? It’s completely reversed from Carbide Motion.

TIA!!

I think I figured it out. I had to set the Material Home as 0,0, then it seemed to work…mostly. Still having trouble with the Position tab not moving the the specified location. It’s hit & miss for me. It’ll work just fine, then stop responding. Probably need some custom gCode injected somewhere. Any thoughts?

Thx,
Andy

There is no Fix Intermittent GCode command. Check for loose connections or USB communication issues.

Thanks Mikey. I think it was a n00b to concept issue. I figured it out after a little more experimentation.
