SHARCS Problem: Aperture wheel nominally succeeded but...
Manifestation:
-
ShARCS Aperture wheel has trouble unambiguously arriving at some commanded positions (e.g. Pinhole-100um), reporting:
Unknown, nominally succeeded but...
-
Aperture wheel recalibrates succesfully and can be sent to the Open position reliably,
but other positions are less reliable and the Pinhole-100um never settles
unambiguously into its desired position (even after repeated recalibrations).
Solution/Recovery:
-
Set Aperture wheel MOE to On.
-
Command to desired position (e.g. Pinhole-100um).
-
Set MOE back to Default.
Cause:
-
Persistent positoning issue.
-
"Some days it just relaxes when the motor turns off and will still move just outside the range that is set to be on-target.
-
Temperature dependency not ruled-out.
Associated Issues:
Change Log:
- 2024-12-20: First version.
