Hello,
Little UP, I was a little busy to follow this topic.
Is there something that can be done ?

I do not like the idea of having heater E2 running all the time, other than that everything seems to work well.

Hello,
I have successfully controlled a Berd-Air by E1 heater for month but I made a mistake in reconnecting after a modification. I have probably reversed the flyback diode.
The sentence was immediate.
When the pump started during the print, I got these messages followed by a shutdown of the printer:

• M106 S0.1

• list itemError: short-to-ground reported by driver(s) 0 1 2 3 4

• list itemError: over temperature shutdown reported by driver(s) 0 1 2 3 4

• list itemWarning: VIN under-voltage event (5.1V)

I managed to restart the board and everything seems to work properly except E1 heater.
It is continuously running from the start (E1 led is on).
I connected a fan on the output and is always on with no pwm.
I don't see visually damaged component on the board.

Which component may be causing the problem?
And if it's hard to replace, is there a way to disable this output?

Ok, I will contact seller.
For information, r11-r14 corresponds to what trace, upper or under side ?

Indeed, I made a mistake on the units on my mulimeter, but I still have this important differences between the two resistors.
I have for r11 - r13 : 35 ohm
And for r11 - r14 : 16.6 kohm

Yes, I saw this thread too before make measures.
I took the measurements as shown between R11 right and R13 R14 left several times.
I can try again.

So I took some resistance measures.
I did not dismount everything, just unplugged the 8-way connector.
Between r11 and r13 I have 0.03 Ohm and r11 and r14 I have 16.60 Ohm...

So it's not easy to see even with a 30x magnifying glass.
I can see the filaments but I do not know if they are cut or if there is a contact.
Below, it's a little blurry but it's representative of what I can see :

I will make some resistance measurements tonight.

@dc42 said in Faulty z-probe on Smart effector:

magnification

I does all my fisrt testing without fans and it was already triggering.
Then I tried the card alone with only the z-probe connected, with the same result.

I will watch and try to send a magnified photo

Hello,
I'm new to Duet3D, I purchased a duet2wifi in begin of february to replace my previous board (Lerdge x) on my delta.
I begin to get used with the configuration, little more difficult than with the Lerdge firmware but so much more possibility of settings. I just started playing with pressure advance, so great feature.
I also bought a smart effector with 713maker adapter for rostock ballcup.

But I have problem with z-probe.
It continuously trigger even with the board alone (without heatsink, arms...), green trigger light and 1000 value in web control.
I check documentation and all wire, everything seems ok (tested with voltmeter).
For the moment i use my old nozzle zprob from lerdge.

I make a request to the seller (e3d) which ask me to post on the forum.
I was careful to use nylon washer under each screw and assemble each element correctly.
After inspection of the smart effector board, I suspect a tiny defect on the strain gauge near the brand logo:

Do you see other possibilities or tests to be done?
