Hi all!
I've done mastering with EMD device for new KUKA KR8 R2100 ARC HW 2 months ago. I didn't use robot a lot...about 2 hours in a day.
I have problems with accuracy. And I decided to check mastering. And there was errors: axis - 0.04 deg, motor - 5 deg. I master it two times for checking repeatability. Result was the same.

It's 0.7 mm at 1 m distance. It's very bad for me. Why is it? How often I need to do mastering?
Axis 2 had 0.01 deg error and other axes had smaller error.
I have wall mount of robot.
