Mini height sensor board, USA Manufacture
This is a US manufactured circuit board assembly and cable based on the DC42 design. More information on how this version came to exist and how it is being used can be found here. Includes the board and Approx 1m long PTFE insulated cable. Boards are available with straight pin and right angle connectors.
A Mini Differential IR height sensing board for 3D printers provides the following features:
∙ A differential modulated IR height sensor. The sensor detects the target height by looking for the reflected light from two separate LEDs to be equal. The two LEDs are positioned such that they reflect light into the sensor at slightly different heights. This allows the sensor to be used most any bed surfaces.
∙ A high degree of immunity from sunlight, incandescent artificial light, and other background sources of IR.
∙ Unlike capacitive and inductive sensors, the sensor measures the height to the top surface of a glass bed, not the distance to a backing plate.
∙ A red LED indicates when the head is at or below target height.
∙ Small size, ideal for use where space is restricted, such as under the effector of a delta printer. The current (version 1.1) board is just 24mm wide and 18mm high, small enough to fit below the heatsink of a genuine E3Dv6 hot end.
∙ Automatic selection of a 4level analog output for printer electronics that support it (e.g Duet), or a digital output for other printer electronics.
