Hello all

Well recently I purchased one of those Inventables CNC mill kits which are basically great little machines for hobby stuff but I want to upgrade it for more accuracy. Basically the main problems I have found with the basic kit is squareness of the XYZ makerslide rails. The ends are not square and they have a slight amount of twist. Anyway I want to replace the makerslide extrusion XYZ rails with similar components that are more accurate and have no twist or other anomaly that effect accuracy. Can someone here recomend anything? I'd be interested in hearing from some of you guys who have been down this road and perhaps ran into the same issues. Please advise.

Christine
