My BL Touch not self testing or deploying

Hi
Do you have a Duex5 board connnected to your Duet WiFi?
You have specified H3 in the M307 command when setting up the Z-probe and, if memory serves, that heater is on the Duex5 board.

@fcwilt I'm pretty sure that was the code I got off the generator a week ago. I only have the duet2, no Duex5... Do you know what it should be? John

@fcwilt I understand what you're saying now after thinking about it for a second. H3 I thought stood for heater 3 which is on the duet2 in the large expansion slot. Not sure of all the terminology.

@fcwilt I'm not at my printer right now but I remember the red wire going to I believe 5 volts the black wire going to ground and then the yellow wire is on the pin labeled heater 3.

Does this help?

Ah... You are correct. I never looked at the wiring setup for a Duet WiFi only. They are using pins on the expansion connector and are using the pin for heater 3 which would be on the Duex5 if you had one.
Now I understand what those extra connector parts, that came with my BLTouch, are for.
All I can suggest is that you triple check
your wiring since it will be easy to make a mistake using that expansion connector they way they want you too.I believe you want the brown wire, not the black wire, connected to the expansion connector. I know they are both supposed to be ground but it never hurts to do it just the way they specify.
You might also include in your config.g file the command to clear an alarm condition on the BLTouch. I recall reading somewhere to do that.
M280 P3 S160
Will keep thinking on this problem of yours.

@fcwilt thank you. I miss stated black wire, I meant Brown. The only thing I can consider is somehow heater 3 is not sending the signal with the code as is. Will have to Google some more... The only problem is that I think I have read what is available and have set the code according to what I thought was right... Wrong! Lol

If you go here https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe
and go down to the BLTouch section, that wiring will work with V3 of the BLTouch.
I have it working great with independent Z motors and mesh grid -
@Phaedrux this is one of the articles that I used to help set up the BL touch. Even though it's not working correctly something's wrong somewhere. Probably having to do with heater three that I'm using but I'm not sure how else to hook it up...
-
@Whitestsand if you think its an issue with heater 3, you can try one of the other heaters on the expansion connector.
what happens if you send the M280 command with different angles?
