@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?

L.Merino · 2018-05-23 00:10:33

Solucionado.

pansang · 2018-05-23 03:49:38

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

Thank You

Hi, I have installed an NX4832T035_011 but it does not link me correctly.
When the printer is not printing, from the main screen, it does not let me do anything. When I put it to print from the computer, it lets me stop printing, but it does not do anything else either. I attach two videos.

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

ah, my fault: no "sudo" for "cd"... just
cd /home/pi/nextion

To install the latest version:
1. Download the latest version with the command $git clone https://github.com/Tibus/TouchScreen-For-NanoDLP.git
2. replace files from the /home/pi/nextion folder with TouchScreen-For-NanoDLP files
3. Install the IP module. To do this, go to the /home/p/nextion folder and run the command $sudo npm install ip
4. To view the current slice when printing: In the file /bin/plugins/nextion/pages/printingHome.js
remove the word "nextion" from the following block:

case 11:
_context2.next = 13;
return this.nextion.getValue("t12.x");
case 13:
this.imageX = _context2.sent;
_context2.next = 16;
return this.nextion.getValue("t12.y");
case 16:
this.imageY = _context2.sent;
_context2.next = 19;
return this.nextion.getValue("t12.w");

Seems that you tried to fix the issue in the bin-folder, It should instead be fixed in the src-folder:

sudo nano /home/pi/nextion/src/plugins/nextion/pages/printingHome.js

then look at the following code section:

this.imageX = await this.nextion.getValue("t12.x");
this.imageY = await this.nextion.getValue("t12.y");
this.imageWidth = await this.nextion.getValue("t12.w");

and change it to

this.imageX = await this.getValue("m0.x");
this.imageY = await this.getValue("m0.y");
this.imageWidth = await this.getValue("m0.w");

Please be aware that not only the 'nextion.' was deleted, but also 't12' had to be changed to 'm0' (this is the object-name of the placeholder on the 'printing' and 'printingPause' screens).

Then the the changed src folder need to be compiled to the bin folders by...

cd /home/pi/nextion
sudo gulp

Most likely gulp is not installed on your raspberry pi by default. You need to install it first to compile the source code changes.

Regards
ToS

PS: as soon as I find time, I intend to upload changes to my fork on GitHub and initiate a pull-request to Tibus/ Julien. But it's uncertain how fast the code change will result in a V 0.4 (which would make sense anyway, as there is still the issue with missing packages in V 0.3)

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

Hi there, is did all the following but still get TCP/IP instead the address displayed

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

The Shutdown and the Reboot buttons also do not work, but the Plate and Settings Buttons are fine.

Bill Dung · 2018-08-09 07:57:12

I reinstalled everything again and now it's working.

xfmax · 2018-08-28 01:46:18

Nextion does not display the current print image.

Youle_FR · 2018-08-29 21:14:40

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?

AKlion · 2018-10-25 16:16:48

Tell me please, if I buy a monitor like this, can I connect it without any problems so that everything works?

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

{ nextio: { port: '/dev/ttyAMA0', sleep: 30 },^M

I'm stuck with the same problem on a RPi2B and a Nextion Basic 3.5". I'm running v2. I think I tried all solution I saw online, but I can't find the issue.
I initially thought it was a permission/serial port issue, but after some checking I just realized it's should not.
I did find the problem. I just did not realized you need to change the url in config.json when using non-standard web interface port.
{
  "url":"http://localhost",
  ....
to
{
  "url":"http://localhost:PORT",
  ...
where PORT equals to your port number.
I am writing back in case someone else could find the same problem.
It might be nice to add this info in the README for other users, just in case. Or otherwise any kind of debug info when program cannot connect to the interface. I had been messing around a lot with the serial settings, thinking it was a pi serial configuration problem. Killing node process and running it from console with
DEBUG=* node /home/pi/nextion/bin/index.js
I could notice that program hang after successfully sending the first commands (sleep=0,bkcmd=3,etc) but there was no debug info like "cannot connect to url". It might be helpful to debug configuration.
PS: Thanks again for the great work!

Hi there, i´m using a Pi2B just like rob. I can´t make it past the "connecting to printer" screen. I was able to connect to my pi an the screen threw WinSCP and i changed the config.json file. That dind´t work so far. I tried to get die .log from the nextion but this file doesn´t show up in Win SCP. Has anyone an idea what i´ve got to do to get that said file?
Would be great if someone got a hint for me.

lumacäke · 2018-11-30 17:05:06

I Think i´ve found the problem with my screen. It´s probaply the node js server. When i install it by following the instructions on githup, i get the following messages:
