juliendelnatte: 

Take a look at "2.4_LittleRP.HMI", which is the one I modified for my LittleRP resin printer.  If you look at home.js, you will see four new buttons with objnames c0, c1, c2, and c3. 

I then reference them as I did in the following two files:

https://github.com/sgraber/TouchScreen- … es/home.js

https://github.com/sgraber/TouchScreen- … es/home.js

The /button/press/0 event calls an M8 gcode which disables my stepper.  The /button/press/1 event calls M9 gcode which enables the stepper.  Pressing either of those buttons do nothing to my stepper motor at all.  If I log into http://localhost/ I can click the button on the webpage that calls these two urls and they work.

I'm at a loss why it's not working.

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?

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

Ok, I'm trying to get my 2.4" Nextion screen working with my LittleRP / DLP printer on a Pi 3.  I followed the above and now have successfully gotten the nextion display to function.  It shows the GUI and I can successfully us it to start a print.  However, my DLP will no longer display the layer images during printing.  The display just stays completely black.  Any idea what might have caused this in the above instructions?

Thanks but that did not work.:(  I started see the same problem...

FWIW I pretty much exclusively use Asiga Stomp to make .slc files now which I then upload to NanoDLP.

Take a look at how OctoPrint does it for FDM printers:  http://octoprint.org/download/

They have you manually edit and configure your WiFi connection by editing octopi-network.txt on the root of the flashed card when using it like a thumb drive.

I will say the one thing that drives me nuts is that I have to hardwire my Pi into my router for the first time use to get WiFi setup.

Ok, I'll do that this weekend.  I need to get a bunch of prints done first. 

FWIW, I would uninstall the latest version and go back to Build #1220 and try it as I know it worked with that version on my Pi 2, but I don't see a place where previous versions of NanoDLP are available for download.

Edit:  Is there any way you could add a page to the current website for previous releases?

Shahin:

I have the exact same problem with the latest build available for download.  If I plug the Pi 3 into a HDMI TV, I can see the bootup text scroll past when I first power the Pi.  However, if I plug it into my projector and reboot, I do not see any bootup text nor will the projector display Calibration images nor sliced images during a print. 

I'll give you the whole background:

Prior to last night, I had an old Raspberry Pi 2 running NanoDLP and I had frequent kernel panics with it - happened every 2-4 weeks.  Thinking it was the SD card, I replaced it with a new Sandisk 32GB card.  I obtained a kernel panic a week later, so I upgraded the pi to a Pi 3 with a 2A/5V power supply, Sandisk 16GB microSD card last night.  My projector is an Acer X1240, which only has a VGA port.  However, on my old Pi 2, I was successfully using a HDMI --> VGA adapter for months with NanoDLP and my LittleRP so I know the cable adapter is good.  I used the latest stock Raspbian Jessie Light September 2016 image from https://www.raspberrypi.org/downloads/raspbian/ followed by using the command line to manually install NanoDLP.  I plugged in the HDMI/VGA adapter and VGA cable, turned on the projector, and then powered on the Pi 3.  I did not observe text scrolling from the projector - nor any images at all.  NanoDLP ran fine and I accessed the Calibration tab in my browser and clicked on the Display button for each of the calibration images.  Nothing appeared from the projector.  I performed a sudo apt-get update / sudo apt-get upgrade and rebooted.  Still no change.  At this point, I'm a bit confused what is going on as it should be displaying something - even during bootup.

Any help would be appreciated!

Ok, I wondered if it needed a delay in there, so here's what I'd try next:

G1 Z25 F200
[Delay 10]
G1 Z-25 F200
[Delay 10]

The delays give enough time for the platform to fully extend and decend before the next command.  Try it?  This needs to go all in 1 button.
