Re: How did you use the FP motors?
To power the bottom two joints in our arm. The lowest is fp on DeWalt 15:1 driving a 20:1 worm driving a 19 to 92 tooth #35 chain 92 tooth drives the arm. Total ratio is 1452:1. Next is fp on DeWalt 15:1 to (20:1 worm has to be assembled at buckeye) then 30 to 135 in #25 arm walks around the sprocket. Total is 1300:1. Tried to use fp at 47:1 and 11 tooth to 135, (567:1) too aggressive and has issues with anti-back drive pins, may have let some smoke out of the motor, good thing we are coming with spares. At least there is less work to be done this year compared to last. We are limiting the fp's to 9 volts RMS in software. Last joint is jidico and globe directly linked on a 19 tooth driving a 135 in #25 chain. (987:1 if you start with the globe). Crossing our fingers and hoping our scale was off by at least 5 lbs.
