To big steppers?

[JAZZCNC]

At 10800 mm/minute (is 10.8 m/minute with 10 mm pitch) the 2 Nm had 0,8 nm of torque left, which is enough for my machine.
The cutting force was set at 100N in these calculations.

I cant run higher speeds on a ball screw of the length I am using.
Steppers with higher torque had a torque curve that plummeted as soon as they start rotating, the 2 and 3 nm motors were comparatively flat.

Ok if you don't want to listen to experience and would rather go with calculations then who am I to argue.
