Hello Shahin,
i've finally had some time to play around some more. I rebuilt the electronics to use the built in pulse generation. Everything works flawlessly now.
There seems to be a problem with saving configuration though:
Whenever i change any value on the system setup page and save it, it is not written to config file. There is no error output in printer.log. The "save" is completely ignored. Saving machine configuration or adding machines works. it's just the setup page.
What i've tried so far:
- install newest beta #1370
- check permissions for json files in /db
- use default config
- if i change values manually in json and reboot printer, the new value is used.
I can provide you with logfiles as soon as i'm home. Meanwhile, if you have any suggestions, please let me know. I will try asap.
Cheers

Hi Adam,
I could not reproduce the issue. If any issue happens on nanodlp side it must display a related error on dashboard. If there is no error on dashboard, it could be browser issue, which does not post data.
Do you know how to use inspector tool on firefox/chrome?
Offline
Yes, i know how it works. Will compare it to other setup pages.

Hi, thanks for pointing out that it might be a browser issue. My browser didn't show me form validation errors. Projector resolution was 0.
Working fine now!

Hi Shahin,
I'm also having issues with the beta version saving - but only on the mask upload page. I double checked on firefox and chrome to make sure it wasn't just the browser not updating.
Thanks!

I double check there is no issue on binary. Do you see any error reported on dashboard?
Also checkout address below, it is mask path.
/home/pi/printer/public/plates/mask.png

Hi Shahin,
I'm not really familiar with the raspi file systems, do you want me to ssh into it and look at the above file address - see if there is a file? I'm guessing so and if there is no file then upload manually to this location...I do not see errors on the dashboard.

Yes, if file correctly generated or uploaded it must be there. After connecting to rpi through SSH you can run command below to make sure it is there.
ls -l /home/pi/printer/public/plates/mask.png

I have seen where the LCD resolution is backwards and when I save it, it does not stick. Same thing with the serial port. I changed it one day trying to get a pi working where the serial port wasn't seen and then every time I try and change it the system would go through the motions but not save the file so I had to edit it manually.

I have checkout whole saving process, it looks fine and not modified for ages.
Checkout dashboard after save. It must throw an error.

Hi Shahin,
I am having issues saving the settings to the raspi, as well as an update:
1. Notification from nanodlp that a new version is available. When I try to update, I get cannot connect to nanodlp. I ssh and get the same issues.
2. I updated for 4k in config files. When I update for resolution in projector settings, it can take several tries to get it to update. After sudo reboot, settings are lost. Also, when attempting to introduce the gcode for the shutter, the same issues happen - though currently it will not take shutter open command (saved shutter close). And the original projector resolutions are set again. It defaults back to 1920x1080p each attempt at submitting regardless of single change or multiple changes.
Is this a dashboard issue and connectivity between computer and nano?
Is there an ssh location to adjust and save these settings?
How can I upgrade to most recent version? Do I need to diagnose the nanodlp connectivity issue?
Thanks!

1. Is there any visible error?
2. Which build you are on?
Offline
Hi Shahin,
There is no visible error other than the notification that it cannot communicate with nanodlp. It begins the download and then I get the error about 2 minutes in.
Where can I see the build number, I was looking around for that...It may be #2229, it states what is new with #2229 on the dashboard page...

Hi Shahin,
I reloaded the disc image and started from fresh install. The problem seems to be remedied. Perhaps I did something in an incorrect order. The only issue I now seem to have is changing the thread pitch. I completed this in the config.h file and on the set-up screen dashboard. It seems to be roughly a factor of 10 off. I'm sure I can figure this one out. Does the dashboard have any influence on the printer - is it overwriting the config.h values?
Thanks again for the prompt response.

Oh, #2229 has bug caused upgrade issue. No it could not interfere into config.h values.

Thanks!
