How did you get the boxes to stick to wall like that

Life's been great ever since.
Yell if you have questions.

But it is still not what I'd call buttery smooth in some positions. Maybe it will keep settling in after much more use? Does that sound like it's within normal tolerances for these Orion 2-speed Crayfords?
It definitely should not be raspy; metal-on-metal is not good. I would disassemble and inspect it. Mine was not raspy, but rather it would not hold a heavy ep. When I tightened it, it did not tighten evenly - it was either too tight or too loose with the slightest adjustment. I disassembled it (down to the last o-ring) and put it back together making sure the L & R adjusting screws were screwed-in the same amount. It is now buttery smooth (I use my little finger) and easily supports my heavy ep.
1) Slightly and equally loosen the left and right adjusting screws by turning CCW.
2) Slightly tighten the center set-screw by turning CW.
3) Equally tighten the L & R adjusting screws by turning CW.

I'm going to have to call Orion about this.
I agree that's the smart thing to do.

I've always wondered how easy are the XTg dobs to move around manually, to pan the sky?
The XT8g is not as easy to move in az or alt as the XT8i because you have to overpower the friction of the clutch(s). So for panning, moving it manually just isn't practical. For panning I use the slew buttons on the hand controller (you can select a slew speed). I can keep my eye in the ep and fingers on the slew button(s). I don't have to look at the hand controller at all while I'm panning. I had an XT8i for many years (in the metro Detroit area) - great scope. But the XT8g tracking is a great feature.
Thanks Dan! I added the XT8i after I got the 8SE; I didn't want to be 'tied down' to a power source. I watched the videos on the Orion website for the XTg scopes and specifically the one for the XT10g shows Ken panning the scope around very easily. So your report conflicts with what I think I saw.

Well, I changed my mind. I had issues with my first XT8g and it had to be replaced. It's movement was very stiff. I never realized how easy the movement is in my replacement scope. After I watched your video link I tried my scope in manual mode and low & behold it surprisingly moves quite easily. Personally, I would rather use the slew control, but in answer to your question, yes you can use it manually if you wish. (I am going to delete my post.)

So I did the email, and got nothing but silence. After 24 hours went by, I emailed again. Still nothing. After 12 more hours went by, I phoned and was put off yet again. I have to say at this point I'm more than annoyed with Orion.
So I decided I had nothing to lose, so I disassembled the focuser to see if I could figure out what's going on with help from the forum, and elsewhere online.
It turns out there were *two* problems. First, the friction track on the draw tube was not flat, but concave. So the crayford shaft was riding on just the two outside edges of the track and this was producing the grinding noises. This has been reported on the forum before. Also, the tension adjuster was not working right because one of the two parallelizing screws had been cross-threaded at the factory, so the teflon bearing was COMPLETELY out of whack. So I removed the tube and lapped the friction track with a whetstone until it was truly flat. I also fixed the threads on the teflon bearing by running a screw all the way through it from the backside a few times. When I put it all back together it works much better now. However, I note that my focuser did not have the rubber o-rings depicted in the document I linked to above. Is it supposed to? I also somehow managed to lose one of the locking screws while I was working on it. Don't ask me how, I was in one place the whole time...

Add a fan, upgrade the finder, and you'll have a great scope!

Now I have an intermittent issue with the handset, which occasionally reboots itself, sometimes screwing up the LCD contrast setting in the process. And the RDF will not align with the scope even with the adjustments maxed out. So I'll have to log a call with them for these issues. Overall I'm not too pleased with the "2nds" process at Orion. I saved 20% but inherited more than that in headaches, many of which could and should have been detected and fixed before they shipped. I'm confident I'll get it all worked out, but it's taking a lot of time and troubleshooting...
Still, this is a great scope and I'm happy with my choice. But if I had it to do over, I'd have bought a fresh one at full price. I incorrectly assumed that Orion would have gone over and "refurbished" this one before sending it out. That appears not to be the case, or at least whatever process they do put it through doesn't cover enough detail.
