More info

3D printer z-probe Touch uses the same servo signal which used in previous servo line.
■ Solenoid Push-pin Up ➡ servo signal 90Degree(ex : M280 P0 S90 )
■ Solenoid Push-pin Down ➡ servo signal 10Degree(ex : M280 P0 S10 )
■ Manual Self-test ➡ servo signal 120Degree(ex : M280 P0 S120)
■ Alarm Release ➡ servo signal 160Degree(ex : M280 P0 S160)
※ 3D printer z-probe Touch can be operated in the following condition.
- One I/O (PWM or Software PWM) for control
- One I/O for Zmin
- GND and +5V power
However, Firmware updating might be needed on a case.
If you use this on an Anet A8 then you need to cross over the YELLOW & BLUE wires. Couldn't figure out why it wouldn't work until I read the head unit. The Yellow is the endstop and the Blue is the pwm input, I just cut them and reversed them.
