Received my probe today which came V3.1. My duet board is V1.02
All working good.
Wired as per tutorial:
Probe VCC to expansion slot 5V on Duet
Probe GND and Servo GND to Z Probe GND on duet
Probe Signal to Z_PROBE_IN on Duet
Probe Servo to expansion slot Heater7(PWM5) on Duet
Used all the code in the first post.
Thank you for help

Just not to create another topic. I have this issue where after print, on the next print BLTouch does not deploy. I have to switch printer off, then back on for it to start working again. Is this a known issue or is there a fix for it?

@Agniusm

setup a macro to re-set the probe...

@Agniusm Please share your current config.g, homeall.g, homez.g, deployprobe.g, retractprobe.g, and slicer start and end gcode. And refresh me on which firmware version you are using.

Agniusm

@JayJay thanks. Is this how its supposed to be used, the probe? I mean do all of them needs reseting or just on certain boards or on certain firmwares?
@Phaedrux i have not made changes since using inductuon probe so my homing gcode is the same and slicer start and end script was not changed. Maybe i just need to call reset macro in my slicer end script like suggested above.

Phaedrux

Well it's not a bad idea to send the reset command at startup and the beginning of your homeall just in case, but it shouldn't really be necessary if the probe is working.

@JayJay BTW do i need I1 parameter if i am without Duex?

If you are using RRF3 then no.

Agniusm

@dc42 no, i am on 1.22.6. I have inserted and now it works fine

@Phaedrux
Added M280 P0 S160 I1 to my home all and on slicer's end gcode.
Still does not work.
Homing when restarted works, lead screw axis compensation works, bed compensation works.
I have no idea why after a print it does not drop the pin...

Photos of your setup? Maybe we can spot something.
