I added a button on nextion to send the Gcode "M806" to the RAMPS,How can I implement this?

You need to post gcode with key called gcode to /gcode path.

qingquan · 2017-10-26 10:08:52

Where is the /gcode path? Can you teach me a little more detail?

How can I send the Gcode from nextion to RPI?

I'm looking at the source available at https://github.com/Tibus/TouchScreen-For-NanoDLP

I do not see a /gcode directory. I, too, would like to add a custom button or two to the Nextion touchscreen.

Do you know a minimum of js programming? If you know it then just insert a custom button on nanoDLP and then retrieve it from the .js file on the page where you're hugging the button indicating the id from the nanoDLP .json file

You need to send post request from nextion side to nanodlp /gcode path.

Is there an example of a proper post request that we could use?

It is very easy to do but it depends on your programming language.

If you want it to send through Linux terminal.
wget --post-data "gcode=M806" http://rpi_ip/gcode

Or with jquery
$.post("http://rpi_ip/gcode", {gcode: "M806"})

OR with nodejs
var request = require('request');
request.post('http://rpi_ip/gcode').form({gcode:'M806'})

Is this code written to Nextion's button event?

Look at Julien Delnatte's z-axis page (bin / nextion/plugin / page /) or (src / nextion / plugin / page) there are some lines of code that point to other custom buttons so you can give a precise idea

Hi MaxJewels,Thank you very much for your reply.Where can I find Julien Delnatte's z-axis page, or where can I download it?

sgraber · 2017-10-30 15:23:39

I believe this is what he's referring to: https://github.com/Tibus/TouchScreen-Fo … s/zAxis.js

Ok, I've used the Nextion Editor to add buttons to the home screen (id's are b0 and b2) and I've adjusted the home.js file to include the following:

this.addListener("click_b0", function (e) {
_this2.changePage("/button/press/0");
});

this.addListener("click_b2", function (e) {
_this2.changePage("/button/press/1");
});

From what I see, this should allow me to press on these two buttons and get a changePage call to my buttons I made in NanoDLP.

I assume I hit compile and compiling adds all of the .js files from the repository into the .tft?

Hi

I want to add code to this file"/home/pi/nextion/bin/plugins/nextion/pages/projector.js" to send "M806" code to ramps, can you tell me the specific code?

Replace the original instruction in this sentence:

this.addListener("click_b4", function () {
return _this2.nanoDLP.command("/shutter/open");
});
