Backlash?

Hello,
New owner here of a LXD55 sn 6. I don't know if I have a problem or not with the motors. They seem to spin alright one way but not the other on both motors. Is this what you call backlash? I can't beleive something is wrong with both motors as they both do the same thing. Sometimes it works both ways and somtimes not. I haven't even had it outside to do any alignment on any stars yet. I wish I could explain it better but I'm just learning.
Thanks,
Richard

Hello Richard and welcome to Astromart...

Backlash is "slop" or play in the gear train and affects the aligment accuracy. This is not what you are experiencing.

My guess is that you do not have the telescope properly balanced on the mount so that the motors have to work too hard. WIht the SN=6 balance should be pretty easy, adjust the counterweight so that the RA Axis is balanced when the RA axis lock is released. Adjust the tube end to end so that the DEC axis is balanced when the DEC clamp is released.

Hope this helps
