nanoDLP

Please, get a debug file after printer failed to display layer.

You need to use patched firmware.

Do not use firmware on wanhao website, it is not compatible with nanodlp. Use one on d7 wiki page.

Have you tried asking this question on d7 forum?  Lots of people are using nanodlp together with d7 there, and you could get help much faster.

Did a little further digging - but still not able to find the issue...

Calibration works fine, after reboot - but that also stops working after i do a print where nothing is shown on the screen.

Did tvservice -s and that reported the following:
state 0x12000a [HDMI DMT (87) RGB full unknown AR], 1440x2560 @ 50.00Hz, progressive

When starting the print i monitored the HDMI with tvservice -M
only this was reported:
[ I ] HDMI in HDMI mode

powering HDMI off and ON again, did not make any change (tvservice -o and tvservice -p)  still not able to get the calibration to work after i did a print.

The board in the D7 have a blue light to indicate stable HDMI signal, and it is showing a stady light, which means stable HDMI signal detected.

I also played around with setup/Display Communication Type  - no difference

Im sure its something simple, i just cannot figure it out.

Yep - just tried.

Basicly - as soon as i try to print, then nothing will be shown on the screen and i cannot get anything to show afterwards

But as soon as i reboot, im able to get get the calibration to work again. 

So the "Print routine" must be doing something different than "open shutter" and "turn projector on"

I dont think its a HW issue anymore - as i now have two complet screen circuits (screen and controller boards) and both sets is producing the same result

Im not able to print - every time i hit print, there is no image on the screen.. the UV lights does turn on and off, z moves as expected, but no image what so ever...

that was a good idea...

And confirmed - it does exactly the same,  am able to show calibration on the fullhd monitor, printing a plate shows nothing... and after that im not able to get the calibration to show again.

So exactly the same...

infact it looks like the "printing" does wird things with the HDMI signal - normally my monitors tells me what the resolution is - and it does that when i hit the calibration screen - it shows 1920x1080@60hz - but after the print job - my monitor just shows HDMI - but no resolution info is available..

and when i do a sudo reboot, the monitor comes back immediately and shows the shutdown processes... (i actually also saw that on the small monitor, but forgot to mention that earlier)

ehhh, i dont know to - it will not let me write 1920/1080 - it seems it just wants a number?  so should i put in 1,7 (as in 1920 divided by 1080)

write check, will work

OK
it needs to be inscribed
