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)

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...
