So I built my Kossel Mini to 760/360 extrusions. Inadvertently, I am using the Tridprinting 12" strong wall rod and traxxas rod kit for a diagonl rod length of (340mm). Using Jay's visual calc, it calculated that my Delta radius would be 173.84mm. Directly measuring my Zmax I got 311mm approximately. However, I can't get the printer to level out. It remains ever so slightly convex(~1mm) but I can get X/Y/Z to calibrate to Z=0. Since my rods are shorter than expected (348mm), I'm not sure how much its affecting my calibration. Thanks guys.
