Anycubic Photon Printer Owners 造訪社團 » LCD

Hello!
I just bought the anycubicphoton ...
when I put the UV Detector everything is normal ...
but after printing maybe, 10 minutes ... the lcd shows something else.
an image is worth a thousand words ... (the lcd is new, the first I broke it maybe because of despair)
I have never been able to print.

Hey folks! I tried to find some answers to a major problem I have with my new Photon on reddit, but I couldn’t get a definitive solution. So here is another try, since this group is always mentioned as the best resource for the Photon.
Please forgive the wall of text, but I wanted to give as much info as I could. The story is compiled in an album here: https://imgur.com/gallery/qy52RCe
My initial test lattice cube went awesome! Also the following two miniature prints came out great.
The last four prints after that however had the linked failures/artifacts. Something went wrong with the buildup of extra flags or broken supports or something?
I used AnyCubic grey resin with these ChiTuBox settings https://i.imgur.com/5J6tMwm.png found in some blog post. Auto Supports placement.
After cleaning/filtering/leveling and a another try I was left with what seemed like permanent stains on my FEP after just a few prints. Couldn’t get rid of them for the life of me. I carefully tried the plastic spatula, some IPA and a microfiber cloth to no avail.
Another print made it even worse https://i.imgur.com/cHL1Omy.jpg , so I replaced my mere 6 day old FEP with the spare (removing the protective cover, of course) and tuning it to ~345 Hz.
Meanwhile I found your Photon File Inspector and used it for my next print. These were the settings I chose: https://i.imgur.com/jDCOzyN.png .
I adjusted them similar to what the lattice test file was like that came with the printer. So no more Light Off Delay! Thought that had been my biggest screw up, causing the resin to cure while re-pooling. Heureka?
No. Similar problem with the print (albeit less noticable since the model was thin) and I had a layer of semi-cured resin almost all over the bottom of the VAT. And again, tiny stains of resin remain on the FEP after thorough cleaning.
What on earth am I supposed to do? I'm out of ideas. Is my FEP now broken again ? I will try firmware v4.0.11 (if I can find an install guide for the files that come with it) to try and fix potential light bleed and I will go back to the translucent resin for a test print. But if nothing more helps, I will have to assume the LCD is broken and the printer goes back for replacement.
I honestly don't enjoy to tinker around anymore, the whole deal just isn't made for it unlike FDM, because every failed print is way more work and cost.
Thanks for taking the time and helping out! Sorry if I'm breaking some etiquette, I've never been on Facebook before. 翻譯年糕

Few weeks ago I posted about some lcd error messages, turned out to be a bad motherboard. Today I received a replacement from anycubic. Dreading putting this thing in. Looking for all the tips before I start! Also, praying it’s still functional from the looks of this box.

Update: I removed the silvery flap. Prints are back to normal now. It was displacing the light it seemed.

Just replaced the lcd on my Epax x1, different printer but ideally the same parts and technique.

On the back of the LCD, there is a flap of a silver (almost textured) material attached where the cable attaches to the screen. Underneath is a nice mirror finished part. Do I remove the silvery flap to expose the mirrored area?

I seem to have a spot of hardened resin on my LCD screen. Is there a way to clean this off without destroying the screen? Checked online and I can only find general maintenance and vat cleaning tips.

Has anybody else had their 2K screen die after 4 prints or just due to time?

I got my Photon 11 months ago with a screen that was dead on arrival. Anycubic sent me a replacement that worked for 4 prints before I got busy and started just using my FDM printers. 10 months later, I tried to print again and got a big solid block of cured resin as though the screen wasn't masking at all. Doing the LCD test show this screen is now dead too...

What I'm wondering is: Is it possible that it died just sitting there or is there something else wrong with my machine that is killing the screen?

Ripped off my LCD. Never thought I'd be that guy. Wasn't even resin cured to the screen. My FEP film apparently just got super stuck to the display. Should've used the spatula to separate it carefully.
Anyway, has anyone used this replacement LCD, or have any other suggestions? Thanks!

Hi guys, a new day, a new problem.
Yesterday after my print I saw some resing on the LCD. I think the VAT tank bored. Does someone know what I can do to take off it? That is cured.

Thank you.
