Reprap Fisher Hall Sensor Bracket

thingiverse

A bracket for the RepRap Fisher enables the use of a NJK-5002C Hall sensor instead of homing microswitches. The Hall sensor is available from Banggood: http://www.banggood.com/NJK-5002C-Hall-Sensor-Proximity-Switch-NPN-3-wires-Normally-Open-Type-p-936554.html. Designed in Onshape, the CAD model can be found at https://cad.onshape.com/documents/43651e2c2ccc40319dedcd6e/w/4b43a6d1793a478896207684/e/8a68f2ddec6540609d254ef4. Print Settings Printer: RepRap Fisher Resolution: 0.2mm Infill: 40% Post-Printing The brown wire connects to 5V (preferably) or 12-19V input. Blue and black wires are connected to X, Y, and Z sensor inputs; blue is sense and black is ground. The sensor operates as an open collector, pulling the signal down to ground when triggered. Configure endstop settings in the Duet as follows: M574 X2 Y2 Z2 S0; Set endstop configuration (all endstops at high end, active high).
