Well here goes... Aluminium frame router design

I've got a Nema 34 on my X axis, in theory a Nema 23 would do it but I wanted to be sure....

Cheers, Just noticed your build seems to have a long belt on, Does it whip much on change of direction and whoa, there big pulleys, do they need to be that big? I was going for minimal?

Sorry, that last post was to njhussey, You posted to quick, I know I can get a belt long enough but I don't know if the flex/whip will cause issues such as catching the inside of the box section which I plan on using just because that is whats left from my cut plan :-) If theres a problem then I would rather rectify it now rather than buy stuff that won't work...I'm tight like that ;-)

The problem with big pulleys I am led to believe is the inertia that they have. I have no idea on how much the belt will sag but you can always add the belt cover when you have it up and running.
You will need to run a 70V power supply for the motors.
