The front limit switch tells the control system where the carriage stops at the X-axis end. A failed switch causes limit sensor errors, grinding, sudden stops or collision risk. Fitting a genuine Nocai sensor returns stable homing.

Check the cable first

Power off and unplug the printer before any work. Open the access panel near the X-axis beam end. Disconnect and reseat the front limit sensor plug to clear oxidation. Inspect the cable along its full length for looseness, breaks or aging. If the fault clears after reseating, no sensor change is needed. Proceed to replacement only when the error remains with an intact cable.

If the limit error recurs, the fault may lie in the cable, mainboard or mechanical bracket rather than the switch itself.
