Michael created a new topic ' Linear focus module..' in the forum. 1 year ago

KStars on my Mac, Astroberry talking to home brew Myfocuserpro2, using the linear algorithm; works mostly GREAT

Occasionally focus fails and aborts the session, typically wildly out of focus. If running from the scheduler the session immediately restarts, and attempts focus again but now from an already bad starting point. In linear focus mode the starting point is initially moved out even more, making recovery virtually impossible.

For example:last night initial focus was around 9600, KStars finally crashed with a focused position of 12600, a typical scenario (I believe the focus module might be crashing KStars??)

If the focuser would return after a failed routine to a “last known good” position, this might be avoided...
