Steppers for Converting Sieg X2 to CNC?

[irving2008]

....

In respect of the drivers and the current they can output & the rating of the motors, do the motors only pull the full rating when a load on them demands that? Or do they somehow draw that constantly? I'm not quite sure how that works sorry.
.

As a general rule the power supply should be rated at 60% of total peak current, so 60% of 3 x 4.2A = 7.6A

Switch mode power supplies are not best for CNC work, linear supplies handle the peaky nature of steppers better and are easy to build.

On another note - looks like someone already started doing 3D printer produced stepper mounts:

So will see if I can find design files somewhere....

Flimsy. You have a milling machine - use it.
