I own an MN56 with a JMI focuser. My problem is that this focuser is anything but 'buttery smooth'. At room temp. it is smoother, but still has a 'catch'. As it gets colder, the movement becomes stickier. The slower it is turned, the more pronounced the 'catch' becomes. Any suggestions from other JMI owners would be greatly appreciated. Thanks.
