How do you figure out the Nextion port address?

Hi, thanks for the manual, I couldn’t find anything else on the 1.1 shield. but with English it’s bad and apparently I’m doing something wrong (((I’m trying to improve wanhao D7 1.4. could you give the file an export of your settings, as I understand it, we have the same printer.
a problem with the direction of the stepper motor, the backlight diode does not light up, and the display shows problems

So, do you think that if I replace the 0.01 resistors with the correct values (0.1) I should be able to set Vref more easily?

Great tuto.
I followed step by step, and nanodlp seems to be installed correctly.
After this, I’ve loaded the .tft file into nextion touch. the file is downloaded from the links in your post “Upgrading the Wanhao D7”.
Everything seems to be working, but screen is only showing “Not printing” below: TCP/IP, and once pressed buttons, they change colour but nothing else. NanoDLP browser access works fine. BTW, nanodlp installed build is 2177.
any idea about what could be wrong?

In reply to Nate. There are no vital details missing. The formula is in step 1.1, and what you set VRef to depends entirely on the specs of what you have in front of you. If you don't know simple stuff like what all of what is in section 1.1 means, then you should not be even thinking about doing this upgrade, it's WAY beyond your capabilities and no amount of mollycoddling will produce success.

So you say the Vref needs to be set correctly or the system will completely shut down…

But what’s the “correct” Vref? What did you set it to? Your documentation is missing some vital details.

In reply to Didier GUILLEY.

Not saving config – sorry, can’t help you there, post on the nanoDLP forum and the developer will give you advice.
Nextion not working – You’ll have to figure out which port is in use, change it at the bottom of the machine setup screen, and it should then work
gcode – Direct control does not use gcode.

Thank you for this tuto….
but i have problems, nanodlp don’t save config when i click “submit” in machine settings and the buttons don’t works in nextion screen (i have always memory and cpu at 50% and temperature at 25° and the buttons have no effects).
Can you help me too for the gcode and the others parameters ?
i have raspberry pi3 b+, nextion 7″, lcd 2k 2560*1440 (china), nonodlp shield v1.1, Raspbian Stretch with desktop

In reply to Veysel Ozer. I found I had to have both top and bottom limit sensors installed and configured. Even then, the move down or move up buttons are iffy,
