Z axis opto switch

thingiverse

A support for optical endstop with fine regulation. The support is designed for an omron sx4009-p1 e66 because I just had it from scratch. Unfortunally my ABS reflect the light of the emitter so I had to put a metal plate to switch off che emitter, bad to see but it works. It is composed by 2 part. The fixed one and the adjustable part which allow you to slide up and down the switch. Instructions You need a m3 nut inside the fixed part so you can fine adjust the distance of the nozzle from the bed. with a m3 screw. to make this, if you use repetier host, after slicer the part, find the last layer of the nut housing inside the part, and edit your gcode adding "@pause" somewhere in this layer, the printer will automatically pause the print and you can gently insert the nut inside, then just click on continue to finish your print. thats it. have fun
