WiFi won't connect

Hello.

I've been searching all the threads I can find with regard to getting nanodlp loaded on my raspberry pi3 and finally got it somewhat working. I can now load a file into nanodlp via the dashboard and see the layers output via HDMI to my monitor. As of yet, I haven't connected anything yet - still working out the bugs on the software side.

I have two major problems at the moment that I can't figure out.

1.  The layers are cut off at the top and bottom of the monitor.

( I tried changing the settings in projector resolution section of nanodlp and previewed the changes via the calibration templates. I managed to get the calibration grids centered properly on the monitor, but when I try printing the file the top and bottom are cut off...)

2.  Cannot connect via wifi. I can only connect via ethernet cable.

( I select the "wifi" button at the top right of the dashboard and it brings up the window for setting your wifi network name, security and password which I am able to enter successfully and hit "connect". When I check the dashboard panel the "wifi" is still there - no network name. When I toggle the application log it states that I'm connected to the network, however when I disconnect my ehternet cable the dashboard gets disconnected. )

I am planning on running either GRBL or Ramps board once I get these issues squared away. Any help would be greatly appreciated.

Re: WiFi won't connect

1. You need to change HDMI related settings on Raspberry Pi. Please, search the forum. It called overscanning.
2. It gets another IP from wifi, so you cannot continue using that by ethernet IP. Use upnp other nanodlp functions to find new ip address to connect.

Use latest marlin firmware for RAMPS, it will be easier to use.

Re: WiFi won't connect

Thank you for the quick reply.

I managed to get nanodlp to connect to my wifi network and can communicate with nandlp through my browser now.  

Still trying to figure out why the layer is getting cut off at the top and bottom of the screen. If I hook up my computer to the HDMI monitor I am able to see everything fine without anything being cut off, so it's not a monitor setting.

I tried editing the config.txt file as shown here:

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
overscan_left=16
overscan_right=16
overscan_top=16
overscan_bottom=16

Didn't correct the issue so I uncommented:  disable_overscan=1

Unfortunately, the image is still cut off at the top and bottom.

I have a Ramps board which I will use once I get the overscan (?) issue resolved.

I upgraded from build 1330 to latest stable version - build 1778 - and the problem is worse! The top and bottom of the image is cut off even more than before!

Re: WiFi won't connect

It all depends on config.txt, nanodlp does not have access to such low level HDMI setting.
Try change and experiment with different options on config.txt.

Re: WiFi won't connect

Thanks again.

I put the over scan issue aside for now to complete the other steps in the build process. I currently have a ramps board with an Arduino Mega 2560 but cannot find the GRBL0.9j .hex file for download anywhere. The link given in the Github site just opens up a browser window with lines of hex code...

Are there any sites that have the .hex file itself for download?

for   Arduino Mega 2560 +ramps 1.4  good   marlin  or repetier
GRBL0.9j   good for  Arduino uno

Re: WiFi won't connect

What version of Marlin do I use for Ramps & Mega?

As for Arduino Uno - I have no way of uploading version GRBL0.9j  -  I only get a browser window full of hex (?). Is there no actual hex file I can download??

I am using a Mac with OSX 10.13.2 and I was able to load GRBL-Arduino-Library-master to my UNO board and communicate with it via Universal Gcode Sender V1.0.9 without any problems.

As for nanodlp, I have several problems:

1.  I managed to get nanodlp to recognize the UNO via the browser terminal window, however I cannot connect to the Ramps board via the browser terminal window

I am going to load MARLIN version "mUVe3D/Marlin-mUVe1DLP-Running" to my Ramps board to see if that will work. What (if anything) do I have to uncomment in the Marlin.pde file to get it to work with nanodlp?

I'm getting close to getting everything working together. Thanks to all for helping.

Re: WiFi won't connect

I uploaded MARLIN version "mUVe3D/Marlin-mUVe1DLP-Running" to my Ramps board and hooked it up to my raspberry pi3. When accessing the terminal from the nanodlp browser I got the following result:

I think I'm making progress. Will try and hook up a stepper motor and see if I can get some rudimentary operation tomorrow. I'm trying to build a top down version and any help/advice would be greatly appreciated.
