To be clear - does the Z stepper stop turning? (meaning an electrical problem) or does the stepper keep trying to turn but the bed no longer goes down? (meaning a physical problem)

Using cura (or pronterface - it's free!) move the z axis down in 10mm steps. Measure this roughly with a ruler. Does it look correct?
Is it only moving 5mm possibly? (always consitently half the correct amount? failure mode 1)
or does it sometimes less than 10mm and then other times work fine?
Does it get stuck?
If everything is fine then rehome and move down 1mm at a time for 10 times. Did it move the full 10mm?
If everything still fine, put a ruler on the back corner of the machine as close to the bed as possible. Tape it there securely. Place a pencil or flat ruler or something on the bed so it reaches the ruler. Move the bed down in 1mm and .1mm increments. Test it carefully.
Oh and maybe you can send us a photo of your z coupler (at the bottom of the z screw).
Please answer all the questions that were in the earlier posts. They are all good questions and we need to know this before giving more advice.

Hi Tim! Welcome to the forum!
Do you have an UltiController, or do you print from a pc?
Do you know what your steps-per-mm setting is for the z-axis?
