It occurs to me that one option would be to use the 2nd fan output on the Duet 0.8.5 to control the servo. You could use a diode and pullup resistor to produce a 3.3V or 5V signal from it. The PWM duty cycle and frequency can both be set using the M106 command (with P1 parameter to select the second fan output), so you can deploy and retract the probe by putting appropriate M106 commands in the bed.g file. No firmware changes necessary.
Or you can use a contactless probe like the rest of us.
