Ultrasonic 3D Printer Bed Leveling Sensor

In This Video We Show the Precision of alignG-S as a Proximity Sensor for Bed Leveling and Stage Zeroing.

alignG-S has two measurement modes working simultaneously, Proximity Mode and Distance Measurement Mode:
(1) alignG-S as a proximity sensor: Pin#4 of alignG-S is always 0 (0V) until the sensor is positioned in 5mm proximity of an object; then, pin #4 of alignG-S becomes 1 (3.3V). alignG-S as a proximity sensor has a precision of 2.5 micron (0.0001”)
(2) alignG-S as a distance measurement sensor: The sensor measures the distance from the object and shows the result in its Analog pin (pin #7), serial output pin (pin #6), and PWM pin (pin #8). alignG-S as a distance sensor has a precision of 25 micron (0.001”) and accuracy of 50 micron (0.002”)

alignG-S, is a cost-effective and compact sensor with a Digital/Analog communication port allowing for integration into any project. alignG-S has a modular design. It comes with the base unit (alignG-S) and some external modules (Such as: Development Board, USB Module, Bluetooth, …) that attach to the base unit like the pieces of Lego. AlignG-S alone is useful for 3D-printer and CNC manufacturers, developers, and entrepreneurs. But, alignG-S in combination with one of the external modules can be used by anybody who needs a precision instrument to keep their 3D printer or CNC aligned.
