@Heartleander81

are you using usb to connect to your duet?
see https://duet3d.dozuki.com/Wiki/USB_ground_loops

[Heartleander81]

Only raspberry with spi. I doun't use Usb

[Heartleander81]

This is my wiring

[Veti]

normally when someone post the diagnostics without newlines, its because it was not copied from the web console and they used usb.

[Heartleander81]

I have copy with my smartphone.

But I think now my bl-touch is damaged. I have make a g32 and the bed drive in the nozzel. Bl-touch was red but nothing stop

[Veti]

check the extension wire, that is know to make bad contact and cause issues.

[Heartleander81]

Have make new connections last week bevor i have it install in the HevORT

[Heartleander81]

@Veti

Found the bug. It was due to the contact resistance at the on-board connection. I thank you for the help and patience

[Heartleander81]

ok now i'm confused. Since I no longer trusted the old Bl-touch, I installed a new one. It's the same problem that it just goes in and out without me triggering it. The connection on the board is new. That happens when you print or afterwards. If I had the printer off, that didn't happen for days.

[Heartleander81]

The Bl-Touch doesn't seem to be the problem, nor does the wiring. If the pin is inside or outside, DCW says "not stopped" When I have the BL-Touch off, the board tells me "at min stop" I measure 4-10mV at pin outside with pin inside 3.3V on the white cable to ground

[Phaedrux]

Please post your full config.g and homeall.g as well as the results of M98 P"config.g"

@Phaedrux ok I hope that help.

When I measure from ground to white I have 3.3V when retracted, <20mV when extended. DWC always says "not stopped"
If I measure 5V pin to ground I have 4.94V.

@Heartleander81 I was just reading the BLT documentation the other day and it mentioned it being susceptible to noise from the hotbend heater wires (guessing 12/24v pwm stepping on the BLT 3.3/5v signal) Wondering if this is your issue...

Of course I can't find it now to link...

[Heartleander81]

@BDubs That would be an explanation. Was the fault on the board or was it from the cables? is the best way to shield the Bl-Touch?

Still can't find it...arrg...

They mentioned turning off the nozzle heater (to effectively kill the PWM signal) when probing to prevent it from being susceptible to noise.

In terms of shielding, I'd try using shielded cable and be sure to properly connect the ground/drain to your chassis in such a way as to avoid a ground loop.

[Phaedrux]

M558 B1 will turn off the heaters during the probing move.

@Heartleander81 said in Bl-Touch self extended:

DWC always says "not stopped"

Where are you seeing not stopped?
How are you testing the BLTouch?

If you send M401 and M402 does the pin deploy and retract?
If you send G30 does the pin deploy and start to move the z axis?
Does triggering the pin by hand stop movement?

On the DWC ore with M119 Z not stopped and Z-Probe not stopped

M401 and M402 do the deploy and retract.
G30 do it all. Deploy and start when i push the pin axes stop.

But why deploy the pin when I print ore after print deploy and retract from self?
