Duet Smart Effector not triggering on first probe point

I guess you need to check your wiring.
Does the led light up on board power on?
Does it light up if you tap the nozzle with your finger fairly hard?

I checked the wiring on both ends and they make a connection. The LED blinks twice when powering on and blinks once when tapped.

I am getting this error when activating the hotend: new tool too close to z axis limit. aborting tool change

Does it trigger properly on a single G30?

Can you post your bed.g as well?

Can you post a video of it happening?

G30 results in a successful probe.

Here is a video of it happening. This time it triggered after ramming the bed and grinding against it:

It seems to have a problem with that area on the second pass as well. I'm guessing it may have to do with the sensor wiring touching or coming into proximity with the magnets in the rods.

Which ones fails? I can't tell from the video that one is failing.

@phaedrux
The first point. I have since moved the wires away from the rods and am not getting any failures. It seems to have been the magnets in the rods interfering with the current going to and from the sensor.

Most likely you have a poor crimp connection and one of the wires was only making contact sometimes depending on the angle between the wire and the connector.

That's what I thought, too, so I reinstalled new crimps with no luck
