Hi everyone I finished putting a setup together with the Skywatcher Esprit 80ED with a ZWO EAF. I was having issues with autofocusing. Running it through SGP Pro, the focuser movement was quite erratic. I would occasionally draw the focuser out correctly, other times not, and could rarely draw it in. When I tried the focuser knobs, the focuser itself was inconsistent in its movement. It gets quite tight between the 3 and 3.5 position and again between 1 and 0. I took the EAF off and the same focuser issues persisted. I took the focuser apart and had a look. The four spacing screws were a bit uneven, so I tried evening them up. The rack looks fine. The pinion looked a bit rough and there were some fine shavings in the casing. It looks pretty minor but I'm wondering whether that is affecting the action of the focuser? Is there anything I am missing? I have been thinking it needs a focuser replacement. Cheers!
