@dc42 No, if I take the picture , I mean R70.

That's the Z endstop connector, not the Z probe connector.

I have a V3 bltouch installed as per setup guide for the Maestro. When I turn on the board to BL blinks with an error, I have to turn the board off and on several times before it will do a self test. No resistor is used.

@cabal2000, was the bed too close to the nozzle when you turn it on? If the BLT doesn't have sufficient mechanical clearance on power up, it enters an error state and blinks. I added to my homeall script a BLT error reset command I found in one of the threads here.

@cabal2000 My newest BLTouch does the same thing for me but it will work after turning the printer off and back on once.

@zapta Nozzle is no where close to the bed, pin is free. But I will be adding the reset command. Thanks man

@JadonM Would you be able to share which pins you are using for your setup? I am having some odd issues and want to try to emulate your setup.

Absolutely! I would love to have some novel wiring scheme that would solve all your problems, but unfortunately, I've just followed the wiki! I have the Maestro, which takes different wiring than the Wifi, Ethernet, or Duet3.

My wiring is all on the Z-probe connector and consists of:
BLTouch Out - Maestro In
GND - GND
Control - MOD
5V - 5V

Hopefully that is a help to you, and feel free to ask me any other questions you have!

@JadonM Thank you for the o'scope images

I followed this setup https://betrue3d.dk/bltouch-on-duet-wifi-configuratio-and-usage/ for duet wifi and am unsure about the pins to use for bltouch error reset and 5V logic mode for the duet wifi

I keep getting a flashing red duty cycle and when i run mesh bed it runs for a bit then the probe stays in the up position.

I'm sorry, but I don't think I know enough about the Duet and BLTouch to answer your question. I would recommend making a new thread with all the details and one of the much more knowledgeable regulars can help you.

Sorry that I can't help you!

@JadonM that is plenty of help enough! Thank you!
