All of the sudden fail to slew during meridian flip

I am not sure. Your mount does not support flips using the traditional method so we use an alternate method where we simply issue a slew command when you scope is pointing past the meridian. The logs indicate SGPro did this successfully.

As you can see, the slew completed in 1 second so the mount did nothing to attempt to flip. This usually means that SGPro thinks your mount is past the meridian and EQMOD does not.

We don’t know too much about EQMOD. You may want to read this and see if it helps:

Something with a physical setting or whatnot…
