I have measured and remeasured the calibration values, but every time I set the system to center, it ends up being low. Instead of being 24 in from the top, it is 26 in from the top. Chains are taught.
Distance Between Motors – 3022 mm
Motor Offset Height – 540 mm
Rotation Radius - 120 mm
Is there something I am missing? Any help that can be offered is much appreciated.
