I have a motorized 92" greywolf II I use with my HD70 (came as a package deal)
I need to decrease the drop (ie screen currently goes down too far). According to the manual, I loosen a larger screw in the centre, then another below and to the right, and finally, make adjustments with the next screw to the right.
So I started making adjustments, and bringing the screen about half way up, then let it go back to the bottom of its drop, and am seeing no change. I figure maybe it needs to go all the way up again to work, so I let it go up, and it does not stop. By the time I hit the stop button it had pulled the screen inside the case.
After about 1/2 hour I finally managed to pull the screen back out again. It would seem that contrary to the instruction manual, the rightmost screw controls the stop point going UP, not DOWN. I adjusted it again and was finally able to get it to stop about an inch short of the top, but could not get it back to stopping flush as it did originally.
I then tried adjustments on the screw to the far left, but could not get it to change the lower drop level. Now I have also noticed that if I don't stop the screen manually, it will just keep trying to lower forever.
I am thinking I may have screwed up the limit switches and will need to send the screen back to optoma for repair. Would be interested in hearing from others who have successfully been able to adjust the screen drop on this with any pointers.
