Sorry to revive this old thread, but i was trying to troubleshoot allignment of my mount and ended up here. I only just found out that during allignment via synscan app, the last slewing direction need to be Up and Right before tapping... Will try that tonight hopefully, but... I also have 2.11.A1 Motorboard firmware and was wondering, should i Upgrade to the attached firmware? 2.16 i believe And if i do, can i go back if required? Is it known what the differences are exactly?
