Ok, now I know. I found the Wally thread and I understand the principle. Problem is, that would eliminate the backlash for the last pair of gears, but not for the pairs remaining, that by the way, have to turn more than 360 deg. Anyway, I think DLCJ are good and will try to incorporate them.
I really would like to get rid of that spring. Another idea to eliminate backlash is to use 2 gear trains, one for turning one way and viceversa. Problem is those would be a lot of gears. I have to think more.
