Our Mini Differential IR Height Sensor is a contactless Z probe for 3D printers.
Unlike capacitive and inductive sensors, our 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.
PanelDue is a full-colour touch-sensitive graphical control panel for 3D printers. It is compatible with printer electronics running RepRapFirmware and now Repetier. Support is being added to Smoothieware.
Please be aware that not all of the resellers on the list have the IR sensor in stock at all times
