What leadscrew?

RRF seems to assume that Z movement is done with lead-screws and prints messages like the one below. With the increasing popularity of Z-belts, may be useful to revisit the wording.

Leadscrew adjustments made: 0.029 0.011 -0.001 0.008, points used 4, (mean, deviation) before (0.014, 0.006) after (0.000, 0.000)
Current deviation: 0.006

Is that happening?

I know having used Z belts on a recent printer upgrade that is the way I would go in the future.

I think so. I am judging from the Voron 2.4 which is becoming the flagship model of open source community designs. The main advantage I heard about is the lack of z banding, and it uses gearing to avoid the gantry dropping down when the printer is turned off.

@fcwilt On my hashPrinter I opted for Z-belt mechanism, just because they can be made in any length and it doesn't hurt ($$$) to cut the belt.
Also having the chance to home Z to max at high speed is a plus.
