I have an Avalon M-uno mount with the new StarGo-2 control (Raspberry Pi 4 based). I can setup the mount via VNC or AnyDesk to the StarGO2. KSTARS and EKOS are pre-installed with all the correct drivers.

When trying the polar alignment assistant (PAA), I get an error message when the automatic slewing is supposed to commence.  Manual slewing works fine. The error message states that there is something wrong with the slewing rate. I tried different rates but to no avail. 

In an astrophotography session I can set-up a plan with plate solving, automatic slewing and re-centering. All works. But it does not work with the PAA. 

Any help and suggestions are appreciated.
