Double enstop Z-axis for Tatara

thingiverse

I frequently found the Z-axis misaligned with the bed and thought of this solution to realign the axis at every Home. To implement it, I used standard mini switches with levers: https://www.amazon.it/gp/product/B0717BPW8R/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 M4 screws with corresponding countersinks were also utilized. The holes in the beaks and cones are designed to be threaded with M4 male threads, thus the countersink will prevent movement caused by vibrations. To accomplish this, a second driver in E1 for the right Z-axis motor must be used, connecting the respective EndStop on pins X_MAX In Marlin, comment out Configuration.h: #define X_MAX_ENDSTOP_INVERTING Like commented: #define Z_MIN_ENDSTOP_INVERTING (false - true) Move to configuration_adv.h where you will need to uncomment: #define Z_DUAL_STEPPER_DRIVERS #define Z_DUAL_ENDSTOPS And the game is done. The first supports were printed in PLA but having the printer inside a room that reaches 60 degrees easily, the seat of the rectified bars from 8mm took on a playful tone, losing rigidity to the axis. The new ones, printed in ABS, have no problem.
