I was doing some work On my new shutter install and I came across a problem. when I told the dome to home from about 245 degrees, it started home but then started skipping the gear on the track. i noticed one wheel was caught on a joint between panels. I helped it by hand and it tracked toward home, but then got stuck again. This happened a couple times.
Has anybody had to fill the underside of the dome in between the panel joints with putty or some kind of filler to smooth it out so the wheels don’t get stuck?
Or or maybe find some way to press the gear harder into the track to make it harder for it to skip out?
I've posted a fix for this that spring loads the drive cog against the belt in the "Modifications" forum. This completely eliminates the problem.
I have noted this problem as well. Basically the gear has nothing but the dome to push against and the track that the wheels run in is wide enough for the dome to shift and the teeth will no longer mesh. Ideally the dome drive and cog should be spring loaded against the toothed belt with enough play to account for variations in the dome track. The solution I came up with, at least until I figure out a spring loading approach, is to adjust the spacing between the gear and the belt (shorten it) until the dome wheel is riding on the inner-most part of the track and can't easily move away from the cogged gear any more without lifting the dome. The bolt that comes with the kit is not long enough. Use a longer belt and a bunch of washers to get it where you want it. This approach seems to work, but there's still the "thump thump" issue. I setup that would let the dome wheel run more in the center of their track would make the thump thump better, but then the teeth will occasionally slip when the dome moves away from the cog. Anybody come up with a spring loaded system???
