That's a bad LCD. I had a similar problem with my Photon Zero. ANYCUBIC after-sales support have sent me a new screen.

Daniel J Regan thanks for the response! I have already ordered a replacement but maybe I get a spare lol thanks for the information

Mine was DOA, and screens for the Photon Zero are not available for individual purchase. So support was my only option. Although I am worried because they mentioned they've sent a new 2K screen and the Zero only has a 480p screen. So time will tell. Haha.

Daniel J Regan best wishes!

Yes, it typically just pops off. The glue you might be thinking of would probably just be dried resin that seeped in between the fep and the tension plate

Jayson Jacob Warren Ok so you should be able to open it like this? Even some of the plastic parts broke like they all were clued

Jayson Jacob Warren Like if they all were fused

Alfons Gunnesgård that does not look like it's supposed to be replaced.

Richard Humble So if you need to replace it you need to buy the whole thing with the plastic part?

Alfons Gunnesgård I guess so.

I just did mine yesterday, it was clean. And my Photon came with two feps, yours didn't?

This is a photon zero

Jason Turner You have the photon zero?

Alfons Gunnesgård oh sorry friend. I have the regular Photon.

But still, you should be able to change it. The FEP is a consumable.

Jason Turner yes thats why i thought it was strange

From the images, it looks like resin seeped in as you said and made it hard to separate.

Jason Turner Hum, i sent a ticket to anycubic, let's see what they say about it

Alfons Gunnesgård they are super awesome in their customer service. They helped me with an issue I was having. Great care

Jason Turner I hope they don't say that you shouldn't be able to open it and that I need to order a kit ? If so maybe i need to reglue it after i replace the fep?

Alfons Gunnesgård no, I wouldn't. You'll need to replace the FEP every now and then

Jason Turner So in the case of it's being sold as a unit(holder and fep). I can try to change the fep film, not glue it and see if it works(no leakage)?

Alfons Gunnesgård yes. With all those screws, the FEP acting as a gasket and the recessed track you screw the frame to, there shouldn't be any leaks

Jason Turner ok thank you

Alfons Gunnesgård my pleasure sir.

I wonder how many times you can remove the screws if they are screwed directly into the plastic

I bet that they will do the same as with the Elegoo Mars disposable trays

According to Anycubic advertising, it should be possible to change the fep film.

Janne Sjöström We got answer from anycubic, the fep and the holder is one pice and you need to order it as a kit

Janne Sjöström

Dåligt att det inte är som på Photon maskinerna att man bara kan byta filmen utan behöva köpa ett kit som fördyrar för kunden, sen är det frågan om det skulle det gå att använda Photon behållaren med lite modifiering. Har själv bara bytt FEP film en gång och har säkert kört upp 15 liter resin, filmen kan se hemskt ful ut men det funkar ändå.

Janne Sjöström Ja det är dåligt, håller på att designa en egen hållare där man ska kunna byta själv

Janne Sjöström

Yeah, these were on my memory stick too. Just got my Photon just over a week ago. Had similar issue where prints were sticking to FEP rather than the bed unless I releveled the bed prior to each use. I picked up the Sprectrum mobile app for my phone and tuned the FEP to around 330Hz and did a good print run yesterday without any issues after just leveling it once.

John Bkly As in tightening the FEP? I have no issues releveling every time lol

Yep, tightened the FEP and twanged it a few times while monitoring the results on the Spectrum app on my phone.

John Bkly I had no idea you could do that. Guess I’m downloading that app now lol

If you google it or look it up on Youtube, there are a few vids where they talk about it.

John Bkly Awesome! Thank you!

That looks like a FEP issue, is it the same file each time or a different file but same issue and location?

It happened with different files in the approximately same height too.

Then I would definitely check your FEP, make sure it is tight and clear. If not change it out.

Think about Lift speed

what are your exposure settings (base and normal, IE 60sec & 8sec)? Was the model on the build plate or was it placed on supports?

Hello Tim. Both were placed on supports. First one was straight, second was inclined. Both were 40s & 8s, which was matching the big holy spreadsheet of resin settings.

Hi Merv, thanks for pointing out this resource I didn't know. More reading and testing for me! ;)

Remi Barbarin that first image looks like it should be a flat bottom rather than wavy. Without seeing your support configuration (perhaps not enough, causing the part to flex), there could be under exposure as well which will make the part more soft and flimsy. I'd check the supports to see that they are dense enough and maybe try increasing the exposure time by a second or two if that doesn't help.

Thanks Tim. Will check that out on the next builds. It's very possible I didn't use enough support.

Some useful reading..For what its worth I reckon to angle both ways off the build plate so tip back and slightly sideways if that makes sense..30 degrees off flat and maybe 10 degrees tilt..supports I do auto 50% in chitubox then go around,delete stuff in the wrong place but do all around the edges,corners especially and all extremities...partly to force the resin to print there and partly for support..I think temperature plays a great part 25c minimum, 20% inclusion of a flex type resin will help reduce brittleness , resin brand / type / colour I don't think there is a great deal of difference to be honest..A base colour that will help with painting is as good a guide as any...for me...and yes,some guys always print flat off the buildplate some never have buildplate issues, some never have to change a FEP and some never have failed prints...These people I salute..I'm not that good..or that lucky..or I'm a bit more truthful....Just tickle along quietly and learn from the ones that didn't work..because when it does...Oh Boy :) ..

This Guy is worth listening to : https://www.youtube.com/....../UCbv2mDrRqXovPdahRyoCFh......

Remi Barbarin "the big holy spreadsheet of resin settings" also indicates that it is a reference setting and (environment) temperature can be of influence...
Possibly a combination of not enough support and under-exposure.... (under exposure keeps it soft, suction will do the rest with the unsupported parts)

Honestly, I haven’t found resin to be good for perfectly flat requirements. I mean, you really wouldn’t want to make anything mechanical with this stuff.

Don't print it flat on the bed. The suction twist the "bottom layers"

would not worry about it. printing directly of the bed is where the base of supports are and those are throw away. so alsong as the models stick and tbh the pics look fine.

i tend to print miniatures directly of the base as the base. again the pics look great. :)

I print a lot off the bed as well, and it's just bad enough that it triggers my OCD. :) I'm printing a better test object now - this is my first Anycubic, so my first go with the bed mount / leveling mechanism.

Man, you're asking a 400€ printer to be as accurate as a 26 000 one. Guess what ?

John Driggers I mean, I wouldn’t say it’s OCD until you’re up at 3 AM printing your 20th imperfect cube because you’re afraid your house might catch on fire if you don’t.

No, I'm asking that it be as accurate as a $299 one a single axis. The $26k one I get 0.025mm out of on three. :)

Ah, I see your problem. Your test equipment is too good! Use cheaper and less accurate verniers and the problems will go away ;)

Also, this is a good solution. There are others out there that do the same thing, and on thingiverse if you want to make your own (metal is smarter to use then resin). Set this right, and making sure the photon itself is level to start with, and it'll eliminate that discrepancy pretty well

https://www.fepshop.com/....../anycubic-photon-easyz0-kit/

That looks a lot like what I want - thanks David !

John Driggers Teh you're already as accurate as you can be with a photon. Now if you want something a little better, take a better resin. The machine itself can't get better than that.

David, do you know off the top of your head if the Zero and the "Normal" Photon mounting heads are the same size? I'm not at the house yet....

John Driggers not off the top of my head, no.

agreed. I recommend SPI. Or as we in the machining world like to call them Sorta precision instruments.

It's a chinese printer, use chinese gauges!

Resins have properties FYI, shrink age and elongation. Unavoidable. Some companies clearly state those properties, some dont. The printer itself is not the issue, the resins are.

Try leveling your entire machine, then level the bed. Leveling the bed really only makes it flush in regards to the build plate, but if the machine isn't level, nothing will be...liquids need to be level to the world, the build plate only needs to be level in regards tot he bed

David Collinson just an FYI - not the same, nor the same mechanism. I was able to carefully tune most of it out by repeatedly leveling and retightening. Gonna try and figure out what’s causing it and see if I can come up with a solution.

You think it's the resin that causes one half of the print to be thicker than the other?

you are fighting with exposure(over/under) and bed leveling, best way to avoid those is to put 5mm supports on it.

I had the same problem. I kept leveling and always the same issue. After the first layer it would loose its leveling. Doesn’t matter how much I tighten the top screw! I installed the easy leveler with some adjustments and the problem is solved

Which slicer?

Tried with Photon slicer and chitubox. I have other 4 photons and with the same files they print all well.

oh ... seems like weaken LCD then

It happen in two printers at the same time. I bought this both in the same order. Could be a firmware problem or I must replace the LCD sure?

I have LCD but, It's cheaper the other solution hehehe

Mail to Anycubic they will help you with latst firmware and debug the current one ...if not solved ... then only take step to replace LCD

lot of thanks Deodatta Daulat Gosavi

what is your firmware version?

the latest -1, I mean, I usually update all with the previous version than the current one

Carlo Mariani need to end by .18 for the photon

Simon Leclerc as I remember the version I discard it is .19 so it might be .18

Carlo Mariani absolutely.
