It runs for a set number of milliseconds. It's no where best as precise, but the auto focus routine can still calculate the FWHM (iirc) curve and get closer than unaided focusing.
Simple DC focus motors are supported in Ekos. There are really not recommended at all and I think everyone should invest in a stepper motor based focuser, but they still exist so we gotta support them.
Sorry, it didn’t work. Is apt-get update and upgrade enougth? (Ubuntu mate on raspberry).
Did you changed anything relative to time or kind of? My lx200 sends time and location ok but now kstars does’nt print it well and scope position is moved now ☹️
