Well I wish I could say how easy this was but it took me an entire day to switch over to an all aluminum platen for the Shapeoko 2 CNC. Broke a tap off In the last hole I was working on and it took almost 5 hours to recover from that mistake!!! Without any adjustments the table is square forint to back and only out .005 side to side. I will add some .002 shim stock and hopfully that will bethe end of that. Overall the the CNC is more rigid, but then again I haven't cut anything yet...
