@Schmart Yes, actually rereading all the threads and a message you sent about the use of M918, in my case I put M918 P1 E4 F2000000, since my display is a 12864 with a ST7920. But maybe all my problem is that I don't have a menu and therefore there's nothing to show, rigth?

@bearer @Schmart First of all sorry for not replying until today, yesterday couldn't find time to continue. I know I say it everytime I write but I'm really grateful for all the help you've given me so far, without you gys I counldn't by any change connect the display.

I think that I've read in diagonal all the posts about this LCD and all the suggested help you adviced, even a guide to connect the Ender 3 to Duet Maestro. Since I was running RRF 3.1.1 and then installed @bearer RRF 3.0 I thought that maybe I needed to wipe and do a clean install. What I did was:

• Erase the Duet
• Using BOSSA uploaded the @bearer firmware version 2.05
• Downloaded this menu https://github.com/mudcruzr/Duet-Maestro-12864-Menu-Files
• Copy again all the sys and rest of menus

What happened?

• The same issue but in a thread of another post @dc42 suggested to another person put in the terminal M918 P1 and then voilà the display worked. The funny thing is that in my config file at the end was the M918 P1 E-4 F2000000. What I did was take out the frequency parameter and the display worked.
• On DWC the menu tab was not displayed.
• The encoder works but cannot select anything, the press doesn't do anything.

Then I erased the Duet again and did a clean install of @bearer RRF 3.0. And have the following issues:

• On reboot the display is blank (is lighted but with no text on the matrix).
• I have to manually type M918 P1 E-4 and then the display works
• The encoder works but can't select anything, nothing happens when I press the encoder button.
• The display show correctly the temps, coordinates.
• In DWC now I have the menu tab

My thoughts about my issues are the following:

• The encoder press must have a command or something that I'm missing in the menus since they were made for a Duet Maestro. I know I have to dig in every menu file to adapt it to my Duet 2 Wifi.
• I can't understand why in my config.g the M918 doesn't work

What I haven't find yet is if there's a guide to create menus and the usage of encoder. Could you give me a little assistance please?

@oliof Sorry for taking so long to reply. Couldn't make some time until today to return to this personal project. The change I made from @bearer schematic is ENC_SW and LCD_CS pins, below the image with the changes. I think this could only work for @bearer's RRF3 https://www.dropbox.com/s/f7fjuu7f0wcf7dc/Duet2CombinedFirmware-rrf3-lcd.bin?dl=1.

The only issue I find is that when accesing the SD card on the LCD12864 some lines appear on the display and have to clean them by manually entering M918 P1, even make a macro to just run it.
I'll be looking regurlarly at this posts in case anyone needs help or when @dc42 uploads his 3.2 version. See you guys around and again many thanks to everyone!
