BlTouch 3.1 Flashing and Troubleshooting
-
Same issue again. Touched it with the multimeter leads, it works. Remove them, it stops. And every time I touch it with the leads to measure voltages, the LEDs on the Duet get brighter (so more current draw). Never seen anything loaded by a voltmeter before..
-
Same thing is still happening with nothing connected to the Duet2 except the BLTouch and Vin. All jumpers are in the right place, no steppers or anything really is connected. I am stupified...
-
can you post a picture of the wiring both on the duet and the bltouch for us to see.

Factory wires:
Extensions (top red on control is probe signal)
-
on the default wire
the red wire is the voltage you seem to have swapped voltage and signal.

@Veti excuse me while I drive to Ben Nevis and take a leap off the top.
Fml, serious case of Dad brain this weekend. Sorry to waste everyone's time for something so damn trivial. I have never been more embarrassed.

that is what this forum is for.
sometimes you just need a second pair of eyes to look at a problem. -
@Veti yes. Much appreciated!

Hello all, I seem to be having some similar issues that I cannot figure out. I have tried two BLTouch 3.1 probes on my duet 2 wifi and they both end up getting stuck in alarm mode, flashing red. I have tried three sets of wires and two probes. I have had both of the probes successfully probe my bed, but they all end up in alarm mode. This happened within hours of installing each probe.
Thoughts?
Cheers everyone
