looking for a little advice here please, i am building a mechanism using sp3, and using the built in gear function. the problem is, at a 2:1 ratio(what i need), the gears are not keeping good timing when rotating slow(5 rpm) or fast(500rpm). at a 1:1(what i dont need) ratio, the gears are keeping perfect time with each other. ive tried mocking up actual gears, and under loads, the gear teeth cross through each other. note that ive already messed with gravity, density, and the other stuff to no success. does anybody know how to keep gears at perfect time with each other at ratios other than 1:1? any help would be appreciated. thanks.
