Ender-3 z-axis optical endstop
Description
Hi There. This time, I want to give You handle for optical z-axis end stop. Like a optic sensor, I used standard sensor (RepRap) from aliexpress - 3mm gap. Power +5V for sensor, You can take from motherboard - like on the picture - after fuse FP1. Enjoy. Update: I have checked option without additional z-axis element. Sensor works very good with oryginal frame,which have properly width. You can see it on gif.
