Doesn’t sound like the stepper is the issue. It should be very easy to turn the Z allthread. Check for some interference. is it easy and smooth without the tool on it?
If not check the whole z alignment. I just put one together yesterday and the z axis was super hard to turn and I broke the z motor mount. Turns out I had the Z rails twisted a bit.Unscrewed the all thread from the coupler, pulled the z off, loosened everything up, made sure the mount was on right and snugged it back down, now it moves great.
