Hi,
I’ve been experiencing sequence aborts in the night as a result of the focuser not quite reaching the commanded position. The relevant section of the log is below. The problem seems to start, in this case, as autofocus commands 17247 and the focuser reports 17246. What is confusing me is the references, later on, that the focuser has been commanded to 15747 ‘but’ reports 15747. Is this a mistake, or am I missing something?
My OTA is a Planewave CDK14 with EFA connected via the PWI3 interface.
Any comments welcome. I have lost several nights’ imaging due to this problem and it’s starting to drive me crazy.
