We all know (or should!) that the repeatability of common spring-arm limit switches is crappy at best. I'm looking to build & install one of the precision height adjusters for the Z-axis limit switch, and noticed a post on some forum suggesting removing the arm and triggering the switch button directly (e.g. with a screw end).
Has anyone tried this, and if so has the repeatability of Z-homing improved any?
Sorry -- this is a stock Prusa i3, which depends on physical contact between the vertically-moving subassembly and a microswitch mounted on the frame.
