Hi, If your z-axis threaded rod is T8, the normal step value should be 400.
If it is 2560, it may be too high.
For the calculation of the z-axis, you can refer to this: steps_per_mm = (motor_steps_per_rev * driver_microstep) / thread_pitch
I hope this can help you.

Should that value be exactly 400 or can it possibly be somewhere around 400?

Hi, If it is T8, it should be 400.
You can calculate by referring to the formula: [(360°/1.8)*16]/8=400
