@droftarts @infiniteloop Thanks for your help

@heide said in Inductive on Duet 3 and wiring of the Heat Bed:

I will not place a diode in between, if I have understanded this sentence correctly. Can you elaporate on that?
"Duet 3, Duet 2 WiFi/Ethernet revision 1.04 or later, Duet 2 Maestro: you can connect the output of the sensor directly to the Z-probe IN pin".

Yes that is what I take the documentation to mean. You should be ok without a diode.

@supraguy said in Dead Duet 2 Wifi... Sort of.:

so I'll use an external 5V supply,

This is the way.

Got i working now thanks for the help .

@phaedrux
Well in that case i will have some spares sans a CPU 😝

@phaedrux said in Toolboard sudden death!?:

I'm not sure. That was DC42s best guess.

OK, will send email and fill the form.

@p8blr only if you want to. My guess is that the bootloader has installed OK but cannot be read back via the ICE because the MCU thinks the security bit is set.

To quote DC42

"at what movement speeds do the "phase may be disconnected" warnings happen? Bogus warnings most commonly occur when the movement speed is quite high and the back EMF from the motors at that speed is greater than the power supply voltage. So if the warnings have only started recently, check that the power supply voltage is good and that the VIN connections to the Duet are sound.
If you only see warnings from one phase and it is always the same phase, then most likely the warning is genuine and you have a bad connection to that phase."

@ben-0 so the issue was solved right? The cheap psu didn't output 12v as expected...you may want to put "solved" on the thread title...glad you sorted out!

@jay_s_uk

Then I have made it wrong. I am happy that it has not been powered on just yet. Thanks 🙂

@rjenkinsgb Yep that worked; should have read further I would have found my answer in the doc hehe

Thank you!

@dc42 Any chance of having trigger events that can be used to execute macros immediately before power off and immediately after power on so we could unhook & rehook the toolboard automatically?

@p8blr I'm glad it's working again. I'll mark this as solved.

@matej1006
You only need the

M80 C"!pson"
M80

in config.g, and do not include any M81 in config.g, otherwise it will turn off again.

The setup line with the pson in it should only appear once, ever, to define the pin.

After that, M80 turns power on and M81 turns it off etc. You do not need to repeat the setup for M81.

You would normally only use M81 in a shutdown macro or at the end of a print, in the slicer post-print gcode.

Put the M80 lines near the start of your config, so the power enable is set fairly soon after power-up.

@zipzap Thanks. I have ordered that type. I won't be using the previous relay anymore

I re wired the connector using the twisted pairs as if I was using a usb3 cable and it seems to be working so far.
I probably should document that the the first half of the cable is cat 6a and the second half is cat 7.
Thanks for the help.

@mikeabuilder Thanks Mike!
