Re: Noisy EXOS 2 PMC8?

The exosII is very quiet.  A smooth humming sound with musical qualities when you manually rotate the axes.  If it is making a hacking noise it means the motor is stalling.  Mine did that under certain circumstances.  The cause was binding in the gear train owing to the mesh adjustment.  If you are hearing loud hacking noises then that is the root cause of your inability to align...or do anything.  If your scope is way out of balance you could also cause this stalling to occur.  Have you balanced things?  How heavy is the scope you have on it? If you are balanced and the mount is hacking instead of humming then you need to adjust the gear mesh or send it back for adjustment.
