While threading the lead screw, ensure that it moves smoothly. It should thread effortlessly while the second POM block remains loose.

Gently tighten the screws on the second POM block while rotating the lead screw by hand. Monitor the resistance carefully—as soon as you feel any increase in resistance, stop tightening. Avoid over-tightening, as this could introduce unnecessary drag to the system.

Gently pull and push the lead screw along its axis to check for backlash. There should be no play when performing this movement. If you detect any play, tighten the screws slightly and test again. Repeat this process until the play is fully eliminated, ensuring a secure fit without introducing excessive resistance.
