limit the top speed you can cut at. For instance on my router, it will
rapid reliably at 6m/min (236 in/min) but will only cut reliably at
4m/min or so on steppers. On servos it will rapid and cut at 6m/min. On
steppers it's 1:1 drive, on servo's 1:2 (same 4mm pitch ballscrews). If
I changed the ballscrews to 10mm pitch, the resolution would be less
than acceptable on the steppers, but perfectly adequate on the servos,
but in both instances it would move more than twice as fast.
