New AP1600 slew noise

Luke Dodd

We have finally had some clear skies downunder to use my new AP1600 delivered a few months ago. I have noticed some slews are very noisy, particularly in the RA, but also Dec gearboxes. Noise is high pitch and varies in frequency, almost sounds like the motor is about to stall. Other Slews are very smooth and the noise very consistent. Mount is well balance and scope weighs 30kg, slew speed 600X. Temp is16 degrees Celcius. Is this normal? Thanks
