What was the "Meeeow" sound ~13sec. in the lifting video?
I haven't seen all the pics of this build. May I ask, if you have three point bed adjuster springs ( I'm sure you have ) and what will happen when the print is heavier on the backside. Would this relax the front spring?

I like the new Z belt-worm drive set-up.
Solid, symmetrical, and simple.
What a tank !

Yes moving the end of the screw ~800 um up will move the switch by 100 um, but for the switch to move back to 0, the bed (with screw) must move 800 um down again.Quote

The screw threads are 1/32" = 794 um per turn. The lever is approximately 8:1. Turning the screw 1 full turn will move the switch end of the lever about 100 um, so it is less sensitive to the screw rotation making it easier to make small changes in the bed zero position.
A full turn of the screw will change the relative position of the end of the screw with ~800 um with respect to the bed, no matter the lever action on the switch (assuming an ideal switch).Quote

If the screw were pushing the switch directly, moving the bed position 100 um would require making just 1/8 of a turn. With the lever, moving the bed position by 100 um will require a full turn of the screw.

this is where I think you are wrong. It is the screw position relative to the bed that matters when the screw is attached on the bed side of the lever.Quote
the_digital_dentist
Yes a full turn of the screw moves the end of the screw relative to the bed by 800 um, but at the switch it looks like 100 um, as if you had turned the screw 1/8 of a turn. It's the screw position relative to the switch that determines where z=0 is, not the end of the screw relative to the bed.
