About the only other thing I can suggest is having a look within the Setup Menu at the guiding Speed, normally the Gemini defaults to 0.5x Siderial, might be worthwhile checking to see if that is what is set.
Are you sure the Gemini has the round DIN motor cables, the earlier models had RJ45 connectors for the motors and a different version of the Autoguider Ports and didn't like straight TTL connections.
Cheers
