Re: Screen problem

Hi To me it sounds like you have a bad HDMI driver board. My only advice would be to double check the ribbon cable connections and also make sure the boards are not touching the frame and potentially shorting something out.
Pay special attention to the ribbon cable locks on the socket connectors! 

As far as setting go i can only share what works for me on my YHD101 ( KLD1260)

# CAMERA SETTINGS ( 1 = ON, 0 = OFF)
#start_x=1
disable_camera_led=1
# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

# 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

Re: Screen problem

So if your screen is working and your ribbon cable convertor is working and your HDMI driver is working it must be either you Raspi and/ or its settings

If you load a standard Raspi distro do you see anything on the screen ???   Remember that if your screen is prepped for resin printing it wont have a back light !!!!

Re: Screen problem

One of the first things you should do with a new Raspi is load a basic distro and test its working

https://www.raspberrypi.org/software/

Just read about the basic Raspi set up and how to configure HDMI etc

Re: Screen problem

That's strange  The flashing blue LED would suggest the HDMI is not syncing with the RASPI  . Im not sure about this either as its not really my area of expertise . Sorry i can't be more help.

Re: Screen problem

I'm having the same problem. The screen works fine on a PC, on a laptop, and on OLDER VERSIONS OF NANODLP (build numbers ~2000 or so) but newer ones? Nope. Something has changed maybe in Raspbian's videocore, and the admin simply didn't test it before pushing it out. I'm now stuck with a printer I can't use since there's no way to downgrade back to the working software, and there's no "earlier revisions" archive available for some reason known only to Shahin.

This is extremely frustrating.

Heres a link to my old (est) nanodlp image from 2019 https://www.dropbox.com/s/8cc0npl6w40a6 … p.img?dl=0
Maybe that helps . The link will expire end of Jan
( sorry i cant tell you what version that is )

Re: Screen problem

Thank you. Hopefully it works because this is driving me insane. There is so much about NanoDLP that just doesn't work right. It forces you to choose a distro from the main screen, disallows navigation until you do, and then crashes and can't be brought back up on the web interface. Z movements from direct control are screwy. The screen problem, multiple posts about it both here and on the facebook page with no clear solutions or support from the dev. The fact that updating is just completely broken.

All of this stops it being good, useful, dependable software and yet it seems to be the only one that exists. This is why you shouldn't release software you don't test first.

You are welcome .   I know how frustrating it can be initially but honestly speaking once set up NanoDLP is a great piece of software . I've found 9 times out of 10, issues relate to the Raspi eco system. I think its the price we pay for Raspi being so flexible , upgradable and adaptable.
My main issues were screen set up and wifi but once they were resolved NanoDLP works great. Considering this is free software thats quite remarkable
Good luck

Back the last time I used it, it was great. But since then my printer has been on downtime and the latest updates are just... well I mean, look at how many people are having issues with the 2K screens in the D7. There's more than a few both here and on facebook, and there doesn't seem to be any solution. Also the Nextion support is sketchy - mine connects half the time but the buttons do nothing. The rest of the time it just sits there "Connecting..." and doesn't get any further. Again, check this forum and facebook for multiple instances of people with this problem, who aren't getting any answers.

As it stands, that version you uploaded was perfect. Screen worked, motor works, the firmware was the right date to turn off the UV on boot, and theoretically the Nextion will work as well, if it decides to co-operate. I'm running a test print right now.

Something I'm having trouble figuring out is the motor speed. Since I'm doing direct control, the first thing it does when i start a print is home to the top. But then it craaaaawwwwwls all the way to the bottom and it takes forever, and I can't determine with speed setting influences that. Any ideas?

I have no experience with direct control sorry

Yeah OK but aren't you blaming Nanodlp for Raspi and Nextion issues

NanoDLP runs on a raspberry pi. Additionally, in newer builds, the boot process of the Pi is perfectly visible on the screen - the HDMI connection only craps out after NanoDLP has started, indicating the problem is there somewhere.

As for "nextion issues", idk. Enough people have the same problem as me that it makes me wonder, if the problem was the screens then why are they still being recommended?

Re: Screen problem

It fixed my screen issue, yeah. The manual control thing though is a bust. Wound up frankensteining it together with the old v1.0 controller board I had lying around to drive the motor, and the high-current direct-in-to-out-12 positive rail to drive my LED array relay (with the negative of the relay switch going to the low-side switched FET on the original LED negative terminal).

It works. Perfectly. So perfectly that the only reason I'd buy that "NanoDLP Official Controller Board" is if this one burns out.
