K8200 Vibration Endstop Trigger Fix

thingiverse

The K8200's endstop switches can sometimes trigger during a print due to excessive vibration, particularly during small perimeter zig-zag filling or hexagonal infill at high speeds. This misaligns subsequent layers and often ruins the print. The X and Y motors are interrupted by the triggered endstop, cutting power and leaving the print head in an incorrect position. Offsets can range from minor to several centimeters. Two causes include the actuator triggering the switch with enough force or loose connector contacts due to wear from frequent unplugging. Log messages indicating endstop triggers during a print are problematic. A firmware patch that ignores endstops during printing is available but not recommended, as it defeats their purpose of preventing physical damage. To resolve this issue, install elastic strips over the micro switches' actuators to prevent false triggering due to vibration and ensure connector contacts remain secure. The Z-endstop isn't affected. Always check functionality after installation.
