Diffractometer issues
Centring is not working properly
Check that one of the two centring motors (sampx or sampy) are not on a motor limit (see error message in spec(exp)); if it is true, them check that the cap is well mounted on the rotation axis.
In can be a zoom issue, try to home its position by typing in spec "zoom_init". If it does not fix the problem try to home all diffractometer motors: on ID29 type in spec, "microdiff_init" on other beamlines, "minidiff_init"
