Firmware installation on Duet 2 wifi

[printnoob]

Hello guys.
I got my first 3d printer - a used prusa with an installed Duet 2 wifi with ?klipper? on it, Im not quite sure, there was no card in it. Now - dumb as I am, I thougth i could just go to the reprap tool, create the firmware, put it on the card and boom the mainboard works, like I knew it from Raspis but as I saw then, the webmonitor didnt show up under the ip described in the duet firmware blog entry. Now I believe, I have to totally flash the board, but I dont find any good explanation for this? Sometimes its just "press the erase button" then sometimes "short these pins" and sometimes both. Then another question is, do I need to undo all the cables from the mainboard whilst flashing? Could somebody please share a stp by step guide for dummys on "How to flash reprap-firmware onto the Duet 2 wifi"
btw sorry for my bad english, its obviously not my mother tongue

This is the file structure I created with the reprap configurator, I included the wifi credentials already there, so no need to install bossa, right? ...right?

You'll need to flash the board directly with a USB connection and BOSSA software.

Follow these directions: https://docs.duet3d.com/en/User_manual/RepRapFirmware/Updating_firmware#fallback-procedure-2

Use this bin file: https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/Duet2CombinedFirmware.bin

You'll also need to prepare the SD card with a folder structure. See here: https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card#creating-the-file-structure

One of those folders is WWW this folder needs to contain the web interface files. Download this zip file and extract it to the WWW folder. https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/DuetWebControl-SD.zip

At that point you should be able to startup the board and connect to it over the network using these steps.

https://docs.duet3d.com/en/How_to_guides/Getting_connected/Getting_connected_to_your_Duet

Once you're connected you should do a full firmware update using the normal process which is as simple as uploading a single zip file to the system tab of the web interface. This is normally how you would update. https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/Duet2and3Firmware-3.4.5.zip
