@Andre267 can you check the content of your errorOutput.log file in the nextion folder?! If it indicates the missing IP component it would give an explanation why you cant see the ip adress and also the rest of the code is ignored. In that case just follow the instructions in my previous post and it should work.

@juliendelnatte: did you read my previos post? The new dependencies (ip, drivelist, child_process) are missing in release v 0.3

As a temporary workaround, the components can be added manually after installing v 0.3:

sudo cd /home/pi/nextion
sudo npm i ip
sudo npm i drivelist
sudo npm i child_process
sudo shutdown -r now

@Andre267 @juliendelnatte:  there you have it "Error: Cannot find module 'ip'..."

@Andre267: you can fix this with executing those instructions of my previous post

@juliendelnatte: I doubt the issue in this case is caused by messed up control-ID's, maybe you could rather take a look into the potential issue with the modules and add ip, drivelist and child_process for v 0.3

Hi, I'm following     

Install guide for guys who using pi3 modeb, but stop at "Connecting printer..."
Thx for Tibus's help...

But when I get to point 4, honestly, I have no idea what to do. Can you help me please?

Install through
But the screen time to select the plate. Do not see the USB and The machine will hold.

Thank You

Hello, I realized that when I turn on the screen, I see TCP / IP, instead of putting the address.

Could this be the cause of my problems?

I'm sorry, I do not speak English and I have a hard time following conversations.
Thank you for the answer.

When I put
sudo cd / home / pi / nextion

Tells me

sudo: cd: command not found

Thank you very much!!!

Yes

hi ~!
Thank you all in advance.

I like the attached picture, the basic function of nano dlp,
  I want to create the ability to move layers one by one on the plate. What should I do?

and I would like to show the progress of the file uploading on the screen using the percentage or progress bar. I do not know when it will be completed, so I am frustrated .... haha

I reinstalled everything again and now it's working.

Good morning,
I just finished installing my "nextion" screen, but I have a problem...

It connects well, but it's very long.
The menu displays well, the buttons change states when you touch them, but I can't navigate through the menus. Additional indication, the IP address field is empty...

I read a lot about the BT/SERIAl, but I'm lost!!!!
Has anyone ever had the problem?

I AM DESPAIRED !!! I spend many hours to get it work but i dont !!!

I want am clear manual for beginners to install the Nextion on an RPI3B+!!!!

It is very difficult for somebody with no programming skills to get the display work on rpi3B+
So i want to maken an PDF / Manual for beginners to help ...
But first i need to get it work by myself.

My display stops on CONNECTING TO PRINTER...
What i did :

Download the new Nano DLP RPI Image from
Nanodlp Homepage

If you use Windows download ETCHER and install it.

Unzip nanodlp and start ETCHER

Select Image you want to flash on your SD Card
Select nanodlp and flash it

Download Putty from putty homepage

Connect your RPI 3B+ with an ethernet cable to your router
After flashing sd put SD Card into the RPI 3B+ and start RPI

Go to your router interface ( in my case 10.0.0.138 ) and login
Watch in your Router Interface and look for RPI 3B+ ip-adress

Open Putty on PC and type in ip-adress from your RPI 3B+  and click open
Then you come to the putty interface box and you can login to your RPI 3B+

Login as: pi
pi@10.0.0.5´s password: raspberry

Now youre on the RPI 3B+
Type sudo raspi-config and make some settings in the “Raspberry PI Software configuration tool”
The Changes debends on your system or on the country you live

Got to 4. Localisation Options and change
    Change Locale to    “de_DE.UTF-8” (ONLY IN MY CASE)
    Change Timezone to    “EUROPE” and then “BERLIN”
    Change Keyboard layout

If all settings changed     got to finisch and click enter

Now you see the black putty interface again. Now update the RPI3 B+ and type
    sudo apt-get update
    sudo apt-get upgrade
    sudo reboot

Congrats so your RPI3 B+ is in ground configuration !!!

Now Type the Ip-Adress from your RPI 3B+ into your webbrowser

Now you can log in to your NanoDLP interface on RPI 3B+

Here you can chose different types of preconfigured Printers. In my case I use the “mUVe3D” Version. Click on it and RPI 3B+ restarts

After Restart look if there is an “New Version Available” in the right upper corner.
If yes click on it and “Upgrade to the latest stable version”

Now the RPI 3B+ update and reboot again

GET NEXTION TOUCH DISPLAY WORK ?!?!?! ( Here I need Help !!!  )

Go to github
And download the tft file for your display. (in my case the Nextion 3,2)

Put the tft file into an emty MICRO SD Card
Put the card into the cardslot on your Nextion
Power on the nextion and it will update automaticly
If ready the display shows 100% success

Now get back on Putty and log in to your RPI 3B+ and check your serial0/serial1 connection

Type followed lines
cd /dev
ls- l

Now you have to scroll up and see followed picture
Serail1 -> ttyAMA0

Type
Sudo raspi-config
Go to  5 Interface Options

First question:         Would you like a login shell to be accessible over serial  NO
Second Question:     Would you like the serial port hardware to be enabled  YES

The prompt will read :        The serial login shell is disable
                The serial interface is enabled
Select ok and allow the RPI3B+ to reboot

Type
sudo nano /boot/config.txt
add fllowed line to the config.txt
    dtoverlay=pi3-disable-bt
exit and save changes

sudo reboot

After reboot you log in over putty again and type
cd /dev
ls -l

Now it should show follow lines under serial

Serial0 -> ttyAMA0
Serial1 -> ttyS0

Download Nextion Screen Software for Simple installation

..../V0.3/pi2_3.tar.gz --no-check-certificate -O - | sudo tar -C /home/pi/nextion - xz);cd /home/pi/nextion; sudo ./setup.sh

NOW MY config.txt SHOWS

# Enable audio (loads snd_bcm2835)
dtparam=audio=on
disable_camera_led=1
hdmi_pixel_encoding=2
start_x=1
gpu_mem=128
enable_uart=1
dtoverlay=pi3-disable-bt

MYcmdline.txt SHOWS

dwc_otg.lpm_enable=0 console=tty1 root=PARTUUID=b94f2c65-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

BUT MY DISPLAY ALWAS SHOWS CONNECTING TO PRINTER….

What is wrong  ?? What changes I must make to get it work ???

Update:
Nextion Output.log
