Inductive proximity sensor holder

thingiverse

This is a simple holder for an inductive sensor and fan for auto bed leveling on the Anet A6 printer. I now have this on my printer and it's almost fully operational. A few more tweaks will get me there. When it's done, I'll publish the .stl files. This was designed for an 18mm sensor: LJC18A3-H-Z/BX Approach Sensor Cylindrical Capacitive Proximity Switch NPN 6-36V. It is somewhat larger than many people use. If you need another dimension of the 18mm sensor, I can add one with the correct hole size. In some cases, keep in mind that you'll have to make a change to the x-axis limit switch because the sensor holder will hit the left end of the printer before the limit switch does. Bed leveling on Anet A6 printers finally works now. Firmware files are available at https://github.com/JohnnyTheOne. On 05-11-16, I added Sensor holder NPN r4 18mm.STL with small changes at the back and a place created for hexagon nut. On 09-03-17, I added Sensor holder NPN r4 16mm. On 18-01-18, I added Sensor holder NPN r4 15mm. On 05-02-18, I added Sensor holder NPN r4 12mm. On 15-09-19, I added Sensor holder BL Touch, 3D Touch. On 09-03-17, I fixed a bug in Marlin 1.1.0 RC8 for Anet A6 printers. Firmware files are available at https://github.com/JohnnyTheOne/MarlinAnetA6. To finish the setup, you just need to set the z-offset after flashing. The 18mm sensor position is X offset: -31 mm and Y offset: 20 mm. The 16mm sensor position is X offset: -30 mm and Y offset: 20 mm.
