When sending it back to the zero position (zero_slew command), it stopped unexpectedly at 11.3 meters and 11.0 meters. We zfined/cen the cart to be sure. When tracking back the star, found the fringes at +500 microns. We changed target, the cart passed at 11.30m and stopped unexpectedly again. New target , cart stops at 12.15m. Then it behaved very nicely....
