I guess its about time to call it "Build Complete". It will only have few cosmetic enhancements from now on. (lettering the box and machine's connection panel etc.) I have done some cable management for the control box; And some calibration; Before the upgrade I was having imperfect circles due to backlash, it now seems pretty good in drawing mode. Hopefully it will be the same when cutting aluminium. Drawing random circles in different dimensions to check... And it is pretty accurate..
