Hi there.
Im having big issues with my lathe. Z axis started to judder and alarm out (ORD1 contour monitoring Z). It does this randomly. Now the X is jumping and alarming out when trying to reference (ORD1 contour monitoring X). Our main service company have looked at it numerous times and now washed their hands of it! Anyone got any ideas, ive checked all connections. Any help will be much appreciated.

Many thanks,

Marx
