4' x 4' x 8" Router Build

Hi Jazz, thanks for the reply, I appreciate the help.

I thought I'd read about gearing the motor / ballscrew to lower the screw speed to prevent whip whilst keeping the motor running at it's most efficient speed? Maybe I've got it all wrong. So 1:1 is the way to go is it?

As I mentioned the electronics side of things is really not my strong side, the more I read about it the more lost I get. Could you point me in the direction of some suitable closed loop steppers? I've had a look but they seem to be around £200 each? I had been thinking of going with a UCCNC ethernet controller, is this a good option? Do closed loop steppers need a different controller & drives?

I had put the big pulley on the motor based on what Joe did in his video: https://www.youtube.com/watch?v=gQz9G_Dlv3w about 45 seconds in.

The cable chains I have modelled are 50 x 17.5 internal - I'll increase this to 25 x 58mm as you suggest.

Thanks again
