Steppers for Converting Sieg X2 to CNC?

[Cret]

Ok that's more great info and I'm learning from this stuff thanks! Great to have this assistance in avoiding some of the packages I might end up regretting.

I might message the seller and ask about the PSU thing.

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.

Be nice if there's a package at a sensible price that suits the X2 specifically so I'll look a bit further but may potentially come back to this second one. Maybe.

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.
