Is it possible t have DWC play a sound (M300) while paneldue is attached?
I need a louder sound than Paneldue can produce.

@dc42 pullup resitor between expansion pin 43 and E3_stop, switch between E3_stop and ground? (I already used the nearby 3.3v pin 3)

Yes, This works with a 10KΩ ....

my bad.
line was before global !!!!

Re: DWC system folder password?

I still thinkt this would be a welcome adition.

blocking direct access to this folder would protect it from users who do not know what they are doing.
students using a printer running Duet sometimes find themselves in the sys folder clicking something.
Clicking on something in the sys folder opens the file in editable form, some text can accidentally be injected and saved... with all undesired effects

Yes, it would not allow for full pretection.
But it would be a small hurdle you can't 'accidentally' cross.

@fcwilt Hi Frederick,
When the surface is not flat (1 side is much higher compared to the other ) or even curved, after scanning the surface we can still print over it properly as the nozzle will follow the scanned mesh.

Our Z end stop is the same as the IR probe. IRprobe = Z end stop.

@T3P3Tony the echo worked... but in the config.g that M550 was in the wrong location...
I use an external file with all globals, this was loaded after the M550 command,
...I was not paying attention...

@dc42 any way to do this without adding parts?
Is there another (set of) free pin(s) I can use with the switch wired as is? (E0 and E1 stop are used, as are all standard endstop pins.)

I did switch to the shielded cable to the E3 (pin9/ GND-pin2) but this dd not solve it. another machine layed out like this with much shorter wires does work.

The strange thing is that when I test wire it on E3 (pin9/ GND-pin2) with a10cm wire+NCswitch. I also get inconsistent response. echo states are Always 0 pressed or unpressed. However, when I switch, the board does trigger...

@T3P3Tony Thanks! That explains it all. i now know how to mitigate this

Is the EM sensitivety of a simple endstop switch connected to E2 (pin9) and GND(pin2) on the expansion higher compared to the same endstop switch connected to E1_Stop (E1 and GND)?
I am getting unexpeceted results in reading the switch connected to E2. That wire is 60cm longer,,, (260cm compared to 330 cm... that extra 60cm length is unshielded but twisted.

@T3P3Tony it just returns the name to : My Duet...

I cant even get

M550 P{global.AccName}

to work...
i dont get it.

hi, does anyone know how i can use multiple global variables into one string with the M550 (printername)?

global AccName="Myprinter"
global serial="467"

How to combine these two behind the: M550 P.....

Thanks!

@Yao I think this was solved by reducing the probing speed to a maximum of F400
