@bearer I was just trying to point out that is something needed for some scenario, in any way, even if we are in our own private network. There is no need to "reinvent the wheel".

Activating HTTPS is necessary if someone wants to create a Progressive Web App that communicates directly with the printer.

@dc42 Yes, I have. Thanks!

So, the solution is to change the grid and then execute the mesh bed probing, so that the height map file is updated.

My previous board was a Duet2 Wifi and there the IR probe was configured to work in analogic mode. Infact at startup it used to flash 4 times.

With Duet3 board the documentation says that the DC42 IR probe must be configured with mode 8, that is digital. Now at startup the probe flashes 2 times indicating the digital mode.

Why it does not work anymore in digital mode on Duet3? Or am I missing something?

My configuration is Duet3 + Raspberry + RRF 3.0 (2020-01-03b3).

In the beginning my mesh grid settings were:
M557 X38:268 Y61:254 S40.0:40.0

I changed the mesh grid in config.g as below:
M557 X38:268 Y61:254 S80.0:80.0

The problem is that when I home Z, the mesh grid is restored to the old values with spacing 40.0 instead of 80.0. I can't find any *.g file with an M557 command.

Where are stored configuration files in the SD of the Rasperry? Can't find them either navigating in the file system.

Thanks.

@Danal I think that Pi has to much features for using it only for having a WiFi connection. But anyway the Pi Zero W is very cheap. Could it work with Duet3?

Is it possible to connect an ESP Wifi module to the Duet 3 Mainboard? I would like to find a way for using Duet 3 in standalone mode with Wifi.
