My KR210 + KRC2 with KR 5.10.6 robot, only when axes are streched is not moving smoothly manually at 100% but in small shaking steps increasing in amplitude as it streches.
Reducing to 30% or better 10% is the only way to minimize it. This is an annoyance when milling with some degree of precision and very slow time consuming.
Since this only happens away from a 1.5m radius approx. I believe that is not gears related.
Any advice as to what is or could be the cause ?
