Thanks for the info but I dont these servo arms are ever going to all level out. By changing the hole I changed the angle, and like a triangle, the the distance is now shorter. The rods were paralell but not are tilted. Dont think the cpu takes this into consideration when priming cause every time nomatter what lengths I make, the arms always follow the same patter. The front remains same level. The right is slightly up, and the left is the highest. Note the left bar is also the longest, that space gone, pulling the arm up over the right side. So servo arms always remain constant. Makes me wonder if the cpu really primes. This info says no. So now every adjustment I make will directly effect how level the plate above is. Trust me, I super glued a knob that broke pulling off, adjusting, rethinking, etc so this is accurate. Really, what does the cpu level if the servo arms always remain in the same PATTERN. Hight ,ay be different but all the other servo arms follow. So should I just eyeball this?
