Innovative and very high accuracy adjustable Endstop for Reprap Prusa and other models
by paolo68, published
This very simple tiny Thing allows a quick and very precise calibration.
This innovative approach consists in:
- FIXING the endstop once and forever to the printer structure.
- Doing the calibration by means of a small and accurate M2 screw (0.4 mm per turn) mounted on the part that moves towards the endstop.
- Enjoying NO PLAY/slack.
Sample application - Prusa i3 Z-axis endstop (see pictures):
- Z-Endstop fixed to the metal frame.
- Thing holding the M2 screw fixed to the bottom of the right X-end.
Note: I have removed the metal lever from the endstop, leaving just the button; this improves the accuracy.
