I do not know your leadscrew pitches, but let us assume 10mm pitch and direct drive (no pulley ratio to consider).

One turn of the stepper motor (200 steps) will take you forward 10mm so your resolution (distance per step) is 10/200 i.e .05mm (which is OK for woodwork).

If you use microstepping, you will gain resolution - for example 16 microsteps will give you a resolution of .05/16 or .003125, which is over the top for woodworking and especially difficult to achieve that accuracy with a wood framed machine.

All that microstepping will do for you is make the motors sound smoother. I would suggest a value of 8 is practical, 16 at the most. Any higher and you will lose speed.

There is a common misconception that you gain accuracy with higher microstep values, but if you look at the way microstepping is done, you will see that for the majority of us amateurs, it has little practical advantage.

Have a look at this article https://hackaday.com/2016/08/29/how-...epping-really/ It is a simplification, but an easy read.
