[CAD_CAM_EDM_DRO] Stepper Motor Axial Travel under compression

Nearly all electric motors have some axial shaft play. Your leadscrew
should have a rigid bearing block, usually with a shoulder on one side
and a backup nut or the coupler on the other, to isolate the motor's
axial motion from the leadscrew. You can then use a coupler from the
end of the leadscrew (sticking out of the bearing block) to the
stepper motor.
