Ender 3 Pro - RRF 2.04 - can't get 12864 LCD to work
-
It shouldn't make any difference; but what happens if you leave out the F2000000 parameter on the M918 command in config.g? Or use a lower value such as F1000000 ?
When using the RepRapDiscount display, you do not need to reverse the connectors, assuming it is a faithful clone of the original design.

removed the G4 line above M918 and deleted the F parameter.The RepRap LCD looks legit to me - labeled "RepRap Discount Smart Controller - www.bigtree-tech"

@ccluck
I had similar problems with a "RepRapDiscount Full Graphic Smart Controller" only displaying blocks.
Can you also remove the E parameter for testing.
That code worked with RRF2:
; Display
M918 P1 ; 128x64 Reprap Display -
@ccluck, the LCD in that picture is the wrong sort. It's a 20 x 4 text LCD, not a 128 x 64 graphic LCD.
-
Thanks David - I guess that's a non-starter then. I truly didn't know that. I think I'll order a 128X64 RepRap LCD off Amazon for $12USD. Worth the investment just to see if these two particular Maestros really will drive a display.
-
So you weren't using the display that came with the Ender?
-
@Phaedrux , yes, I was making every attempt to get the OEM Ender display running, without success. I only just threw the other one into the mix to see if it might work. Wasn't aware that it is an entirely different sort of device. I just pulled it out of a box of Tevo Tarantula that was given to me, read the label that says RepRap...... so I tried it.
To reiterate, my stock Ender 3 Pro LCD doesn't work with ANY of the suggestions proffered thus far. I've meticulously followed your guide, been back over it several times, tried everything suggested in this thread - all to no avail.
I'll buy a RepRap display off Amazon to see what's up - I'll be doubly sure it is a 12864 device. If that doesn't work, then OK, its an ineffable mystery and I'll just continue using an old phone when I need to stand right in front of the machine for babystepping.

@ccluck how do the pins on the maestro LCD connector look?
-
they look OK to me, the connectors are snug when they go on, not loose or wiggly -
@ccluck 
)This is the back side of the LCD board I'm trying to connect - not same as the one in the Duet_Ender3 guide, but it works fine with a Creality 1.14 board and the upgraded Creality "silent" 1.15 board connected to their single ten-pin (EXP1) connectors ( they don't have EXP2 or EXP3 ) Like I said earlier, I have two Maestros here, each easily accessible, so I've tried both with no luck. I must be missing some fundamental key to the puzzle, like it needs some other key besides the M918 enablement.
-
I'm wondering if the pinout on that LCD version is just different.
-
@Phaedrux , me too, but further investigations must wait. GF has persuaded me to take her out dancing at the biker bar out in the woods .... it'll be a nice break from the print room.
-
For all interested parties, I have news - the $12 RepRap Discount Full Graphic Smart Controller arrived today, and instantly worked as it should, no set up or monkey business required to get it going. Yahoo !
So there it is - there is at least one Ender OEM LCD variant out there that will not readily play with the Maestro.
Thanks to all who contributed advice and comments - I appreciate your time and attention to this little issue.

I am glad you got it working.
I changed the main menu files to suit my use.
Top left icon should be Duet3D's icon, next along on top row should be an image of a nozzle, next should be a bed icon last should be a fan icon.
Rem: is remaining time and bottom row to the right of CTRL should be % complete.Should look like this.
I was using firmware 2.04 and now RRF3 and works fine with my Maestro.
Maybe a connection issue....Regards,

@PaulHew , thanks for your support - it is working as I had hoped. I was babystepping with it a few minutes ago. Very handy.
