This modification improves the accuracy of the z-axis homing used for K8200 / 3drag 3D printer.
Without this mod the homing of the x-axis was very inaccurate. Removing the lever on the micro switch reduces the inaccuracy caused by the switching tolerance of the micro switch.
No more issues with too high/low distance between needle and printing bed.
For the mod you need to print two parts:
Parts designed in Tinkercad.
Beside the printed parts you do not need any additional things.
Optional: Drill another hole to fix each part with two screws. This is optional and you do not need to do this.
