I think the issue is the 1074 position is to close to the end of the range. Changing the 1079 O1 focus position from 61.99 to 61.95 to prevent running out of range. This will leave 1079 is slightly worse focus. ___end___ UCoMP COMMENT BY berkey: Fri Nov 12 03:52:17 GMT 2021 Change the focus motor limit switch position, firmware code and labview code to allow motion to get a little more motion in Z. We can now get to 62.2mm consistently. In labview if a position past 61mm is commanded we first most to 61mm stop the motion then do another short/slower move to creap up on the final position. The 1079 position has been reverted back to the nonamial 61.99mm. ___end___ GENERAL COMMENT BY berkey: Fri Nov 12 03:56:18 GMT 2021 Had a nice unexpected window of clear skies between the cirrus. ___end___ ONSITE STAFF: berkey
