I've been testing my unit at home and am finding that the start and end points drift from where I originally set them.
In one of my tests I mounted a laser pointer to the pan/tilt unit, and set that up on a tripod. I set it to do a diagonal move (one corner to another of wall features). Unit is mounted about 6 feet from the wall - even when it returns to start position the first time, it's already about 1/2 inch to the right of where I set it.
If I scrub back and forth, both end points start drifting as well.
I guess one wouldn't notice too much in the field, but I'd like my camera to maintain the framing I set for it in the first place - is anyone else experiencing this? I thought the encoders were supposed to be accurate!
