Essential component for Z-axis position reference and proper functioning of the automatic leveling system. This photoelectric endstop sensor replaces traditional mechanical technology with a contactless, wear-free, and extremely precise solution — ensuring repeatability in every Z homing and a uniform first layer, print after print.

Unlike mechanical switches, this sensor uses an infrared beam to detect the passage of the Z-axis reference plate. With no physical contact, it eliminates the risk of play, bounce, or fatigue from continuous use — common issues in mechanical systems after hundreds of cycles.

The signal generated is clean, instantaneous, and compatible with the leveling system’s force detection algorithms, allowing perfect integration with strain sensors.

Key Functions

  • Precise Z reference: Defines the axis zero point with ±0.01 mm repeatability.
  • Base for automatic leveling: Without a reliable Z signal, advanced calibration systems cannot operate correctly.
  • Fault detection: If the actuator does not interrupt the beam (e.g., due to misalignment or mechanical failure), the firmware can alert the user before the print starts.
  • Vibration resistance: Immune to false triggers caused by chassis resonances.

A reliable zero point is the foundation of every successful print. This sensor does more than stop the Z-axis: it defines the origin of your precision.

In printers like the Centauri Carbon, which incorporates advanced automatic functions (automatic leveling, filament run-out detection, safe positioning, and integrated sensor checks), this type of photoelectric switch enables reliable detection of key conditions for starting, pausing, or adjusting printing processes.

  • Correct installation: ensure the photoelectric switch is firmly mounted on its support and properly aligned in the measurement or detection path; incorrect positioning may cause erratic readings or false signals.
  • Pre-use verification: after mounting the assembly, perform a detection test (for example, with and without filament or simulated axis movement) to confirm that the switch responds consistently before starting long prints.
  • Sensor cleaning: keep the optical area of the switch free from dust, filament residues, grease, or condensation to prevent light scattering or blockage, which could cause reading errors during operation.
  • Care with vibrations and play: the assembly must be fixed and isolated from excessive vibrations from the frame or structure, as this can interfere with the light beam detection and produce interpretation errors for the control board.
  • Functional tests after maintenance: after any hardware intervention affecting the sensor (such as cable replacement, firmware, or structural adjustments), verify that the switch signals are correctly received by the motherboard before starting critical prints.
  • Spare part replacement: if the switch shows persistent failures (e.g., signals that do not change with filament presence/absence or position), replace it with the original or compatible spare to restore the reliability of the detection system.
