ho seguito la procedura ma lo schermo resta fisso sulla schermata iniziale con scritto Connecting! dove ho sbagliato?

On step 3:
3) connect the display and SD as shown in the attached diagram

Can you please tell me just exactly where this diagram is located?

it's pin to pin cable

Could you please at least show me a pictorial of this pin to pin? I still have no idea how to wire this up. I have the Tevo Tarantula 3D printer
Thank you

OK now I see that there is a schematic that you show in your files. It was just that the NEXTION and the Micro SD card holder zoomed in pictures are really blurry and thus hard to read the text instructions on.

Ciao.sto avendo non pochi problemi, con l'installazione del lettore SD. Credo che tu hai risolto. Potresti delucidarmi in merito? Ho già acquistato due tipi di lettori esterni, e nessuno viene rilevato dalla mks gen v1.4 . uso mk2duo v 4.3.6. E nextion da 4,3". Grazie

Hi (o ciao visto che sono Italiano pure io)...I'm about to install an MKS GEN 1.4 with BLTouch, Filament runout sensor and working with octoprint. In the MK4DUO Facebook group they told me that this board in this configuration can't work with this display and this firmware becuase it is too less "powerful"....can you confirm? In case I'm not interested at all in functionality like SD card, buzzer etc..in your opinion if I disable them should I use the whole?
As you can imagine I wrote you in English because I think that this post could be helpful for everyone.


Please, can you make a cover without the "Tatara 3D printer" writing?

hello.how can you actually wire the tx and rx on the board.do i have to connect all 3 jumper with wires from y endstop to x end stops

for end stop x and y use other free pin on board and define it on fw

On the screen I get "SD card update...... No find file" Is there anything I need to do to the screen or sd card other than what you have mentioned?

even if you insert the sd when the printer is off and then turn it on?

It is possible to install this lcd on a trigorilla board (anycubic kossel)

Trigorilla port documentation

I think so, you can try connecting to UART3

How do you hook this up to the Anet A8?

The board MKS1.4 gen needs to be installed and the connection diagram is attached to the project
