Prusa i3 adjustable spring loaded z-axis opto endstop trigger and mount
Description
Hi, I really like the x-axis design of ch1t0 (https://www.thingiverse.com/thing:76660) ... using the spring-loaded counter nut design has improved precision of the z-axis a lot. As i had troubles with the triggering of my old opto Gen7 Z-Axis Endstop i upgraded my custom prusa i3 using this schmagulöl fine adjustable optical Endstop trigger mount. But why spring-loaded? The included spring presses from the bottom side of the nut holder (on the x- carriage) the trigger part downwards. Using this spring-design there is no backlash in the adjustment mechanics possible! Also this Design it is using small diameter M3 Screws for the adjustment - a full turn clockwise will lower the nozzle only 0.5 mm to the bed. Therefore it is possible to adjust the zero-height of the nozzle very accurate and backlash-free! You will need a self-locking nut on the lower end of the screw for this to work out - also mounting is a little bit tricky, see photos. Parts needed: 4x M3 Washers Spring, inner Diameter > 3 mm 2 x M3 Nut 1x M3 Nut self-locking 2 x M3 Screws 5-10 mm 1 x M3 Screw 20-25 mm 1x M3 Screw 25 mm If you found this useful, please donate what you think it is worth to my https://paypal.me/MoneyToMoJo. Help cover the time of design. Thanks, Enjoy!
