Re: Remember Mr. Bill's servo lite?

Thanks Dan. I hope Bill gets a little joy out of his hardware still being used!

That upside test I will remember. I've got a couple optical tachs. I think there is a lot of upside left. I used high count encoders to help keep the accuracy high. So far they have worked great. In reality the max speed of this system us not that important. It's more fun than anything else. During pocketing it could help. Fast moves for sure it will help.

I used to race a lot in the past. Since I don't anymore this is one of my outlets ;) That is if I don't go up in puff of smoke first.
