There seems to be a lot of bashing around those GSO 10:1 focusers. I got them all from Newt to SCT through ED80 and they're fine for imaging, no doubt about that. They're budget focusers and don't handle heavy weight too well but they're a good build and do the job nicely.
As a rule when you image or you're in focus then you should lock the focuser with the thumbscrew and you'll be good to go. If your camera assembly is too heavy and you can't focus up then focus on the way down.
If you're still having issues with the focusing mechanism then move up to a more sturdy type.
