Hi Chris,
I’ve got an etx observer similar to yours but the larger 125 with the same firmware. I’ve had it over a year now and had issues to start as well. Mostly it was set up which does affect go to.
I’ve found the base has to be level use a small level across the base behind the forks not the bubble level. ( as useful as a hole in the bottom of a bucket)..
The compass is affected by metal, the small thumbscrew in the eyetube holder may affect it, remove it to see if the needle moves.
Make sure you have your site as your location accurately by gps and that the timezone is +930. Half an hour out is about 7 degrees as i found.
Enter accurate time at start up, ive got atomic clock app on my phone (free)
Yes train drives as others have said on a distant light pole or stobie they have horizontal and vertical aspects on them to move back to when aligning.
You can also train motors if you change power source or put in new batteries.
Everything adds up and it doesnt have to be out by much to miss targets.
Once working the views are great. Now if only these clouds would nick off!
Hope this helps
Al
