## Summary description

Optical endstop (limit) switch designed for RepRap-compatible 3D printers and RAMPS 1.4 electronics. OEM optical endstop provides non-contact position detection for axis homing and limit sensing. Commonly used on X, Y or Z axes to trigger homing, improve repeatability and protect against over-travel in Cartesian and DIY printer builds.

## Long description

Optical Endstop Limit Switch for 3D Printers OEM Endstop Reprap Ramps 1.4 is a non-contact optical sensor module intended for RepRap-compatible Cartesian 3D printers and RAMPS 1.4 based electronics. The module detects the presence or passage of a mechanical flag or tab to signal axis home positions and limit events. Its optical detection method reduces mechanical wear and contact bounce compared with mechanical microswitches and helps maintain consistent homing and repeatability for X, Y and Z axes.
Advantages
The optical endstop provides non-contact sensing that eliminates physical switch wear and minimizes electrical debounce. It offers fast response time and consistent triggering, improving positional repeatability for homing and safety stops. The compact PCB form factor and standard three-pin connector make it compatible with many RepRap-style controller boards, including RAMPS 1.4, and it is straightforward to integrate into existing printer frames or DIY builds.
Suitable for
Homing and limit detection on Cartesian 3D printers (X, Y, Z axes)
RepRap and RAMPS 1.4 based electronics and controllers
Retrofit upgrades replacing mechanical endstops to reduce wear and bounce
DIY printer builds and experimental or educational projects requiring reliable position sensing
Key specifications
Detection type: optical non-contact sensor
Connector: standard three-pin header (signal, VCC, GND)
Compatible logic levels: typical microcontroller TTL/CMOS 5V systems
Mounting: compact PCB with mounting holes suitable for common RepRap endstop brackets
Typical applications: axis homing, limit sensing, probe/flag detection
How to use
Mount the optical endstop so the printer axis carries a small flag or tab through the sensor’s detection gap at the intended home or limit position. Connect the three-pin header to the controller board endstop input (signal, VCC, GND), observing correct polarity and the controller’s voltage requirements. Configure the firmware endstop type and logic (normally open/closed or inverted) according to the optical sensor’s output behavior and test homing moves at low speed to verify trigger position before normal operation.
Usage recommendations
Place the sensor away from direct exposure to bright ambient light where practical, and ensure the flag or tab reliably passes through the sensing path without wobble. Verify wiring and firmware settings, and perform initial homing tests at reduced speed to confirm correct trigger polarity and position before running full prints.
