Best way to manage vertical forces on lead screw
-
@claustro The outside diameter of the thrust bearing is the same as the outside diameter of the screw. The hole in the centre of the bearing is very much smaller. So the screw sits on top of the bearing - it cannot pass through the smaller hole in the bearing.

@deckingman ok now I understand thank you very much for you patience

@claustro I have taken some photos, will edit them and post tomorrow (Australian time).
Rods and screws at 3 and 9 o'clock and T brackets keep the bed frame (2020 tubing) horizontal. The bed itself is 4mm glass suspend on 3 levelling points (12 4 and 8 o'clock) on the bed frame. 3 is a good number - even the X carriage runs on 3 short linear bearings, 2 on the lower X rod and 1 on the top rod in self aligning slots. The idea is all the mechanicals provide the accuracy. The rods and bearings arranged so no binding on the rods, and with no need for XYZ corrections or bed levelling or Z probes but the bed is only 250 x 250.Can't see your photos. Will you upload them?
