Thanks Dean :)

Interesting to know it doesn't look like 10m/min, I'll try measuring the speed. Haven't verified the steps per yet, I'm merely going off the theory. Steppers are 1.8° per step, 8x microstepping, 10mm pitch screw, set to 160 steps per unit, jogging at 100% (although granted I could be using the UCCNC software incorrectly!)
