Voron 2.4 Build — Z Limit Switch Y Position

The Voron 2.4 has a Z home switch off the back end of the build plate with a steel pin on top. The hot nozzle tip can press the steel pin without melting anything; so once you calibrate the height offset between the switch’s trigger point and the surface of your build sheet, you have absolute repeatable positioning of the height of the tip above your build surface. As long as you never ever change to a different build surface.

If, on the other hand, the Z pin is positioned further back than the tip of the nozzle can travel and the hotend’s silicone sock is pressing the Z pin, results may vary from minute to minute. Literally.
