Zero Y offset 3D-Touch mount for Creality Sprite
--------------------------------------------
When testing the UBL, it was found that the difference between the probe readings and the actual nozzle height increases as the head moves from the left edge to the right. There is always some micro-non-parallelism in the Z pillars, causing the X to twist along the axis, resp. the carriage rotates slightly when moving from left to right, the nozzle moves up and down. This is compensated by the alignment of the bed and is not noticeable when printing. But the probe on the Sprite is located quite far from the nozzle, and the twisting of X acts on it 2.5-3 times more. Which leads to noticeable discrepancies between the actual table geometry and the height map.

To eliminate this effect, I moved the probe so that the offset from the nozzle in Y became zero (and 35 mm X offset). Tests confirmed the reasoning - now the bed geometry and the height map match within the accuracy of the probe.
