I did post this before a while back but tried the suggestion and no change.
My equipment:
Nexdo

  • me observatory with motors
    EQ6-R Pro mount
    Raspberry Pi 3 (trying to upgrade to 4)
    Stellarmate O
S running EKOS / KStars

All runs great on the Raspberry Pi3 which I have Stellarmate installed on.
I'm trying to upgrade to a much faster Pi 4, running either Stellarmete or Astroberry.

Problem:
When I get everything connected fine, then try to sync the dome with the mount, it slews to 270 degrees and that's pretty much it. I don't have any problems running it on the older PI 3, but Pi 4 unit always does this. I have the same problem with either the Stellarmate or Astroberry.
Any ideas what to try? Where in the settings that 270 degrees might be lurking? Can I copy the configuration files from the working Pi3/Stellarmate to the new Pi 4?

I'm totally confused and not sure where to look, I've been all over the settings and not finding a hint of the 270 degree "slew to" or whatever is going on!

Thanks,
Tom
