Yes it's relatively recent but not quite recent enough - the warranty lapsed late last year. At the time I bought it it had not even been put into service but had been sitting around and most of the warranty period was over. Unfortunately it has taken quite a while to discover and analyse the problem...

PS Nearly 2 years on - I heard another user who reported the same problem from an identical model. Seems it is endemic to this Samsung branded Kuka KR10 R1420... something is wrong with the combination of servo motor and drive. I still use the robot, but with work arounds.
BTW KR10 R1100 has the same wrist motors and mechanics.

when something like this happens, the best way forward is to take KrcDiag, perhaps short video of the problem, record motions using trace tool and send it to KUKA. not sure how the MADA looks like but you can create new project in WoV using regular KRC4 and same robot (not Samsung or whatever variant) then do a comparison of files in KRC:\R1\MADA.

Hi. Yes I went through Kuka originally and they first sent a software patch, which did not solve the issue, then eventually said to buy a new motor - but with no guarantee it would fix the problem.. But there is nothing wrong with the motor - both A5 and A6 have the identical motor and both are afflicted to some extent. Seems unlikely they would both be faulty...
Perhaps I will try running the standard version of the robot as you suggest....
