Solved BigtreeTech MINI 12864 V1.0 - Duet 3 Mini 5+

[chuser]

Hello together
I have a BT Mini 12864 connected to my Duet 3 Mini 5+.
The display is identical in construction to the FYSETC MINI 12864

I have turned the tub for the pins on the back so that the pin assignment is correct again.
I have also loaded a menu file.
RRF 3.2.2

But unfortunately I see only one line.
The strange thing is. When I do a firmware upgrade. Then the display shows "Updating firmware".

What am I missing?

Normally it shows the

When updating the

What did you set in your config.g. IE did you set your colours ?

M918 P2 E4 F2000000 ; configure direct-connect display
M150 X2 R255 U255 B255 S3 ; set all 3 LEDs to white

@lodger
Yes this are my config

Thank you, I have tried that.

Which values are loaded during the firmware update. These would work.

@chuser, if the firmware update message is displayed then the display is probably connected and configured correctly. What menu files have you put in the /menu folder of the SD card in the Duet? https://duet3d.dozuki.com/Wiki/Duet_2_Maestro_12864_display_menu_system

[chuser]

I feel a little ashamed.
I have found the error.
The menu files were in a wrong folder.
Now everything works.

Thank you all for the Help

[dc42]

I'm glad you got it working!

If the menu files are not found then the firmware is supposed to put an error message on the display. I will test whether this still works.

Inspired by this thread I digged out a 12864 LCD I used to use with RAMPS/Marlin and connected it to my Maestro.
It worked right away!
Now I'm beginning to think, I might replace the DuetWifi with the Maestro on my CoreXYV printer.
How compatible is Duet2 config file with Maestro?
Both run RRF3.3.b2
Is it just switch SD-cards or are there any wiki-articles to follow?

Mostly? There may be a difference of pin names due to different connectors.

You could load your existing config.json into the confil tool and then change it to the maestro board and seeing what all changes.

@dc42 mine did today when i was messing about.

@phaedrux
I don't use sensorless homing and I've let the steppers run with 1.3A just to try out. It went smooth with reduced travel speed.
To use the maestro has an advatage for me, since I have the two driver extension board, which makes it better suited for dual extrusion than the Duet2. The LCD is a bonus.

Advance notice in case it affects your decision: it is likely that input shaping will not be supported on the Maestro, because the MCU on the Maestro does not have floating point hardware.

Good to know, but I had no ringing or resonance on my prints, so I didn't bother using IS at all. (can we call it 'IS' ? )
With lower stepper current, I don't see ringing become an issue. (Acceleration was 1000mm/s² during the test. Before it was 2000) I could live with that...less noise but almost no difference in print time.

I'm having this exact same problem with the same hardware, I'm sure I'm missing something very simple. I have my display connected and can change the RGB colors of the display by editing the config file, but can't seem to get it to display anything. I have loaded a menu set from the suggested list and changed the master file to "menu". What am I missing?

[jay_s_uk]

@armatus you've put it in the wrong folder. At the top o left of your screen grab it says system directory. Click on that and you should see menu. Upload them there

[Armatus]

@jay_s_uk Thanks, I flashed in fresh firmware and moved them to the proper menu directory. I'm still not seeing anything on the LCD

EDIT: Flipped my cables one more time and now have it working, thanks so much!!!

Hey, sorry to bring this one back to life. I’m having a similar issue with the Duet 3 Mini 5+ and the BTT 12864. Think one of you who’ve got it working to take a pic of how your cables are connected?

[blt3dp]

Omg, I can’t believe it. I somehow managed to plug in EXP2 into the Duet 3 Mini 5+ reversed (it’s dark back there) and I also didn’t think I needed the M150 command. Fixed those and now it works.
