K8200 Precise Z-Axis Home Calibration V1

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:

• Endstop Holder (mounted on the z-axis stepper)
• Adjustment Screw Plate (mounted on the extruder arm)
