Hi Steve
I tried that as well, The problem I came across is it works fine till one looses a step then it seems to escalate, I can get it going with the two motors at a decent speed until the first lock up, Then after that you find for some reason you cant get motors back into sync, at a low speed they work fine, but for a timber router a bit of speed is not a bad thing. Ive being giving it some thought and I agree with the Philosophy that you really cant run twin motors in the way I have been. The X axis should work fine if split one motor controlling either side, the y axis the only way to run twin motors is to have a second ballscrew both driven individually from their own motor. I may have the opportunity in the morning to cut my X axis shaft in half, I will keep everyone posted on what happens after that. Thanks again to all your suggestions it has taken me a long way to resolution of my troubles.
