NPN Sensor Voltage Divider for Endstops.

[massynrt]

Im building a new CNC machine and would like to use NPN proximity sensors for homing/endstops.

24v supply for the NPN Sensor. Will a simple voltage divider (10k and 68k) with resistors be ok on the output of the sensor. Feeding the divided voltage to the STP pin?

I think this was also on the documentation for the probe input. Will this also work for the endstops?

@massynrt the connection will be the same as for connecting an NPN-output Z probe. See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_connecting#npn-output-normally-open-inductive-or-capacitive-sensor.
