We have a Tesastar-i that has rotational movement after rotating the A axis to A90 - does not repeat to same exact B position. Is there any way to reduce this error - almost like it is not seating all the way in the detent position.
When I worked at Valeo, there is also a Tesastar-M head. The guys had the same problem. They called a service person and he reprogrammed the head. The service was 1000 euros. +79608340179 is his number. Nikloai. You can contact him and maybe he will help you remotely.
