I wouldn't have thought so, they are new Heidenhain scales (with calibration certificate). Part of me is saying he should just tweak the encoder scaling, but the numbers he has look like they should be correct. ------------------
Looks like somewhere there's a very tiny error and with the precision the system can do it's always precisely the same inaccuracy that stacks up during a move. Reverse the move and the error "un-stacks" perfectly back to the origin. Like having 100 1cm blocks that are all actually 0.9999cm Stack them up and they make 99.99mm instead of 100mm. ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
