Yeah I will have to tame the beast pal. Nearly had one misshap when messing about with the speeds on the X with one motor disengaged and not slaved, I ramped the speed up a little and I capped myself!!
So if I enter that information I should get the correct movement when I enter movement in the MDI? For example: X100 F300 I should get 100mm travel at a feed rate of 300 correct?

Yes just set velocity to what you feel happy with.!! . . Thou ideally you would have calculated the ratio better to make full use of the motors potential and give better resolution rather than wasting motors potential. To be honest with 6:1 ratio you'd have got away with 3000rpm 400w motors.

Actually I've just thought and I think EdingCNC is limited to 125Khz frequency. In which case you won't get the full 2000rpm from those motors with 2500ppr encoders. You'll only get 750rpm unless you use electronic gearing using the drives, if they have that feature.
For the full 2000Rpm you'll need a frequency of 333khz.

I think your right yeah I saw that in the settings... So will that affect the calculations?

What cpu card are you using and how are you handling positioning feedback from the servos?
