Auto focus failing to move to focus point issue

Hi guys,

I recently had to do a rebuild on my laptop with Windows 10 - not sure if it is related - but have an issue where when the auto focus routine runs after from 1 to 4-5 focus points during the routine the autofocus will start to “hang” saying that moving focuser to new position but nothing happens. I cancel and it will try again and sometime it will work.

Wondering if this is a cable issue, USB port issue or a driver issue?

Being used with a Baader Steeltrack focuser which I have had issues getting a driver for previously and SGP 3.2.0.660.

Below is the last time this happened where I then cancelled the routine.

Happy to attach the complete log file.

Many thanks!!

John.

Hi,

Have you given the autofocuser enough range to make the movement required to get in focus?

This is in the driver.

Clear Skies,
