| | | Chris, it depends on your point of view. As backlash gets less and less, gear train friction gets more and more. The friction is somewhat between the gears but mostly in the shaft bearings where additional force comes to bear. Unless you need (...) (23 years ago, 8-Jan-01, to lugnet.technic)

| | | | Jerry, Precise positioning is my objective. And of course too much friction is a problem. I have'nt fooled around with this too much but, the LEGO gears, as designed, have too much backlash for my project (and as you suggest probably to keep the (...)

| | | | | If you working on a Mindstorms project, then measure your position as close to the output of your gear train as possible. This will eliminate the effect of backlash on your positioning. However if the gear train is expected to hold the final (...) (23 years ago, 8-Jan-01, to lugnet.technic)

I changed the software to wind it all the way back and scan from the same direction (...) (23 years ago, 9-Jan-01, to lugnet.technic)
