I've run into a little problem with decoration spinners. I wanted to make arm decorations move up/down. I figured it would be easy enough. I noticed the decoration spinner has 2 settings...on/off and speed scale. So I thought it would be as simple as using the speed scale setting and activating a 100% strength battery for 1 second and then activating a -100% battery for 1 second. However, it ends up moving more DOWN than UP. Why is this? I have it activated for the same amount of time and same speed for both up/down...how can I fix this?

I don't think your problem is caused by the signal getting wrongly inverted since your decoration spinner already moves up and down. It seems your decoration spinner getting a 100% signal for the downward motion, but less than 100% signal for the upward motion. I think it is caused by the various analog signals not being processed the way that you want. If you are using AND gates to switch the batteries on and off then I think this is where your problem lies. An AND gate will output the lowest analog signal, so if you're using timers the AND gate will be outputting the analog value of the timer and not the analog value of the battery. Try using a 3 port selector to strip the analog component of the timer. Connect a battery to port 1, and connect your two timers to ports 2 and 3. Connect the output ports 2 and 3 from the selector to the positive and negative input ports of a direction combiner and connect the output from the direction combiner to the decoration spinner. How it works:- When you have a signal going to either port 2 or 3 then the signal going to the decoration spinner will be 100% positive or 100% negative respectively. When there is no signal from the timers then the selector will activate port 1 and there will be no signal going to the decoration spinner.

I agree with most of what fluxlasers said. I too think you have a timing problem. I was making something similar and ran into the same problem... The direction spinner favored one direction over the other. I fixed it by using 1 timer with it's output resetting itself and wired to a selector's cycle input. The selector has only two Ports wired to a direction combiner and from there to the deco spinner. I was trying to make walking legs for a top down view. To turn them off I killed power to the chip.

The direction spinner favored one direction over the other. This is not true. If you are experiencing any drift or bias for one direction over the other then it is an issue with your control system and not the decoration spinner.

Sorry, I wasn't blaming the deco spinner. I suppose I could have worded that better. My issue was switching back and forth between timers. It seemed to work better with less logic and only one timer. You have to make those signal durations identical.

Sorry, after reading your message again you meant it to describe the issue you were having. I agree - the important thing is that the time of the signals needs to be identical for it to work properly.
