So, i have taken apart my HEQ5 following the guide on astro-baby and the guide was great. I have not really used the mount before doing this because it was around 8 years old and a bit stiff. So i just figured to get it done rigt away and then get the lubrication replaced. Everything went fine, the parts look good and it has been re-lubed with white lithium grease.
I have been able to get it tracking to around a bit over 1" rms and i am very happy about that. The only thing that seems a bit off to me is that it has to be extremely well balanced. I know balance is importaint, but if it is just slightly off PHD2 will not move the mount at all when calibrating. I will hear the motor move and PHD2 will go through the calibration steps, but the mount is not moving. My total weight mounted is around 8kg or approx 17 pounds. I have used an alt/az eq6 which was much more tolerant of imbalance, but this is also a much sturdier mount with higher load capacity, so not something that can be compared directly.
Since i have no reference on this mount my question is if this is normal? I would like to go just slighty off balance in the direction i am guiding to avoid potential oscilation in the RA axis. If it is not normal any idea if i should tighten or loosen the RA worm gear? If i move the gears by hand it moves easily and smooth(perhaps a bit light?), there is zero play in the axis if i try to rock it back and forth.
