@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 · 20 Dec 2020, 15:20

@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 · 20 Dec 2020, 16:53

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?

Phaedrux · 20 Dec 2020, 17:37

Ok, so the BLTouch is otherwise working correctly, it's just occasionally deploying the pin when it doesn't?

Interference on the servo wire could be possible. Can you separate the BLtouch wires from the rest in the bundle?

Heartleander81 · 20 Dec 2020, 17:47

@Phaedrux I can test it. But take some time. 2-4h. When my child is go to bed, i have more time.

Heartleander81 · 21 Dec 2020, 16:25

@Phaedrux
First print and the pin doun't come out. I think that was it.

So it's working now?
