An occasional problem has developed with ACP and Scheduler. The system goes through 5 good cycles of guiding at which point ACP starts flashing EXP. But MaxIm DL does not begin the exposure. So ACP just sits, waiting for the exposure to finish. Today it sat for 3 hours before I noticed. Yesterday it ran all night without a problem. I have looked at the log files and they say, "guider check OK," but don't say, "starting exposure."
Does anyone have any ideas?
