Genuine BLTouch 3.1 reading "1000" in Z probe on web control

[djstephenson1]

Hello all,

I am having a lot issues with my BL Touch. I just got it in from filamentone, and it is having funny behavior. The blue LED does not come on at all under any circumstance. Nor will the probe deploy or retract when I press "home all" or "home z."

I have also wired it per the duet dozuki, and specifically its section for the Duet Wifi.

When I run my BL Touch test macro it works fine. The probe deploys and retracts as it is supposed to.

I am running it on a Duet 2 Wifi on the latest firmware build (3.0). My x and y axes are sensorless, if that helps.

Attached are my config, config-override, deployprobe, retractprobe, and bed files.

Thanks for everyone's help!

retractprobe.g homez.g homey.g homex.g homeall.g deployprobe.g config-override.g config.g bed.g

You said that "deployprobe.g" (and retract) work when invoked by you. That's good. That verifies a lot of things. That means they are not being 'called' when Z is homing.

Your homez.g (and appropriate sub-section of homeall.g) need to be using G30 to probe. Example:

; Home Z Axis
 
G90 G1 X150 Y150 F10000   ; Move to the center of the bed
 
M564 H0                   ; Just in case bed is touching probe at start. 
G91                       ;
G1 Z1 F50                 ;
M564 H1                   ;
G90                       ;
 
M280 P0 S160             ; And reset the probe, again, just in case. 
 
M558 F500                ; Set the probing speed
G30
M558 F50                 ; Set a slower probing speed
G30

P.S. It is a "style" thing... no right or wrong answer... but I prefer my homeall just call the individual home files, so that I never have to change something (like migrating to G30) in two places:

homeall.g

; Home y, x, z, and Toolchanger Lock axes
 
G91 G1 Z5 F800 H2           ; Lift z so we don't crash
M98 P"homey.g"
M98 P"homex.g"
M98 P"homeu.g"
M98 P"homez.g"

@Danal Any suggestion is good. I will give this a shot and report back. Thanks!

@Danal When I tried your files, I received this error: "G28 Z

Error: Z probe already triggered at start of probing move"

I did restart my machine once I changed the files.

[djstephenson1]

I just discovered a faulty dupont jumper. I suspect this is the problem!

[djstephenson1]

I swapped the wire, and still the same problem. Still reading "1000." It was the white wire that was bad.

[djstephenson1]

@Danal I got it! my white wire had a bad crimp.

[Danal]

Fantastic!!

One last thing-- I tried the stock config home all and home z files, and they did not properly work. Yours did work for me. Thanks, as I still needed those changes.
