That's a pretty cool setup John. I've talking to Donald and their prices are really good. But I couldn't believe those Lichuan servo motors are even better priced than Bergerda ones. That's why I'm considering mostly for the router because I need to fit 5 servo motors to drive it (2 for the Y axis of the gantry, 1 for the X axis and at least 2 motors for the two spindles I plan to install one for high speed milling and one for low speed drilling).
