The sensor works fine. Finding the wiring Schema was a pain. 1 White goes to 5V 2 blue connect via resistor (220R) to 5V 3 yellow is Signal (Pull down via 4k7 resistor) 4 red is GND It would be much more according to standard if Red would be 5V white 5V via resistor blue GND and Yellow Signal ... especially having red as ground is strange ...

Very nice piece. I was a bit surprised at first when the touch did stop the LED but not the vapor but then realized that the switch actually has three states: 1:off,2:led and vapor, 3: only vapor.

Router was easy to assemble even though the documentation was a bit flimsy. The bearings for the platform were alsolut crap and i had to replace them. The spindle attachment works but it should be replaced by an ER11 for better usage. overall a nice piece. The firmware needed to be replaced otherwise the spindle would not start using grbl.
