Ok guys, I've tried quite hard to find some answers on various internet sources without any success. So I'm trying here.
I have a standard Photon, firmware 4.2.18 and experiencing wierd lines on a cylinder printer verticaly.
Antialiasing did not help much...

This is sliced in Chitubox 1.6.1, layer thikness 0.3, antialiasing 4, printed in Anycubic Green resin.

I do not have any other resin to try but the lines are also visible when previewing the sliced file in Chitubox...

Any suggestion how to avoid the lines when printing vertical cylindes? ...except changing orientation :)

Thx for any help ;)

I'd have to say this is an issue with the file, looks like an aliasing issue like you would see on an FDM printer because the poly count was too low...

Thanks a lot Anders. I have quite a high polygon count.
Here are the properties:
41778858 vertices, 13926286 polygons
STL file is 670MB.

Correct :D 1/96 ;)
The whole CSM + BPC needs to be replaced ;)

This is the mesh structure

What are you using to model? is everything "closed"? Slicers hate anything that just a surface, if that makes sense? They can get creative with artifacts like that if something is left to interpretation where it starts and stops.

Don't think this is relevant for curved surfaces, unfortunately

Alexandr Uhlik
2020-03-28 01:23:46

Thanks but this is for angeled prints - I need it printed straight vertical ;)

Alexandr Uhlik
2020-03-28 01:25:23

I am using Rhino3D. STLs are checked in Magics and repaired if needed. The "lines" are in fact on four sides of the part where it cross the X and Y axis.
It seems like the very low X,Y resolution but the Chitubox is correctly set up for standard Photon. :(

Anders Scot Hudson

Check the image below with the angle chart, because that "wall" is on a right angle, you may just be getting aliasing from the LCD as well, photons hate right angles sometimes so it's good to force them to see things as slopes.

Jason Pedersen

Also, this is relevant to layer height, this particular issue is caused by the pixels of the screen.

Andrew Rosenthal
2020-03-28 01:34:44

I get these lines on vertical surfaces too, and wondering what they are. Not just cylinders, but other flat surfaces as well if perpendicular to the lcd.

Jason Pedersen
2020-03-28 01:34:59

Lcd pixels. Something in the anti-aliasing isn't working properly.

Ray Sears
2020-03-28 01:43:44

Alexandr Uhlik is the printer big enough for the bottom sections?
And of course where did you get the STL? I grew up in Houston in 70s and spent a lot time with my rocket model, it was taller than me.

Mark Weller

Pete Kastner

Why can't you print at 15 degree angle?

Alexandr Uhlik
2020-03-28 02:17:52

Pete Kastner I just do not want to use any supports ;) to have a better surface :D :D :D . I will probably think about it. Thanks ;)

not 100% but i think i heard the original photon doesnt anti alias, maybe the firmware 4.2.19 allows it, or in general does it better.

Nikola Pijanac
2020-03-28 09:29:29

The new firmware allows for anti aliasing you need to enable it in chitubox. Problem you could be having with your model is some normal's may be reversed. https://www.youtube.com/watch?v=eLgD88KFKJI&feature=youtu.be this can be done in meshmixer. The p roblem people have at times with oddball things happening to their meshes can be because of a multitude of reasons. I keep stressing that if you have a mesh it needs to be checked. Things like Netfabb and a multitude of other programs from free to commercial can do that. I think Cura can check meshes as well, I know its for fdm but if you check the mesh you can resave and use with the photon.

Nikola Pijanac
2020-03-28 09:34:38

Even though a mesh looks watertight in software, which compensates for the way a mesh looks on screen it doesn't mean its ok to print. When you slice in Chitubox take the time to look at the slices and see if you notice any abnormalities. Yes it could be pixels from the LCD, you'd really have to be unlucky. When artists create meshes they look at the monitor, looks ok, release the model. As to how the structure of the model is, well that becomes the users problem. Imagine it this way you have a building with a lovely facade, everything looks perfect on the outside but the frame on the inside is shot, falling apart or cobbled together. Take the extra minutes check your mesh and you will generally never have any issues again unless they are mechanical.

Ray Sears the CSM stack is my own creation. The rest of the rocket is the old Revell kit ?

Antialiasing question .. What setting do you use? The process should skip a total of pixels each layer for a smoother finish. But doesn't that affect the details? Thank you ?

Michael Pescuma

It CAN affect the details... it comes down to what you are printing. I like to keep mine at 4x to have a compromise between possible detail loss and smoothing.

Appreciate all the past help, im getting more acquainted with resin , but I'm back with a couple more queries!

Photon Zero
Printed on Photon Slicer
0.10
60 seconds
8 seconds

This is my second and third print. Wanted to try something a bit more intricate, but there has been issues!

1. I'm using the 'Hollow' function as standard....is this a wise thing to do? On these pics some areas are more white and solid and I guess that's the bits that cant be hollowed?

2. I'm guessing this shows up more becasue it's a translucent resin?

3. The second pic, i lost an arm (I'm guessing my supports here weren't upto scratch), and the face lost definition, is this becasue the layer setting should be 0.05? It was that as standard, but I changed to 0.1

4. Anti Aliasing is set to 1. This Zero model can go to x16.....would I set it here as standard?

Any advice gratefully received. Ive looked through previous answers and have watched some you tube vids, but would like some direct feedback too.

I am running models again but this time in grey .

Photon Validator seems to be crashing on larger files. It just locks up around 1100 layers in and freezes the entire application. Not using antialiasing or anything. Has anyone had this issue before?

I joined this group a few weeks ago and I have been reading and studying a lot mostly due to a torn achilles tendon. I am grateful for the all the posts and information in this group.
I am getting ready to start my first print using Anycubic Grey Resin. I have attached photos of my supports in chitubox, my settings for the printer and for the resin. Would you review and let me know if you think I have a high chance of success. I have seen a number of failed prints and I would like to avoid that as much as possible. I also turned on anti-aliasing and set it to level 4. My firmware and everything is all updated and ready to go as far as i know. I checked level and did everything per the instructions on youtube and other forums as well.
Should i tilt my project 45 degrees or so? Are my light supports good enough or should i add some heavy supports Is there any reason not to use the anti aliasing Slicing is only necessary for large files that don't fit the print area. Is this correct?
Thanks for your time and consideration. 翻譯年糕

2 questions.

1. My new bottle of anycubic green prints in this faded dark army green colour instead of the candy green see through of the last bottle. Shook it right up and no change. Is this ok?

2.Looking into upgrading to anti aliasing firmware, how do I know which photon I have and which firmware to use?

Thank you in advance

So, I finally got Antialiasing working on the Photon S by using the latest FW and Photon Workshop and exporting to .pws. Great! (Supports and hollowing still sucks compared to Chitubox)

Now, can anyone explain to me why we're not using AA to smooth the jaggies in Z, but only in XY? Sure, we can print at 0.025mm layers, but why should we double the print time when we could print at 0.05 with AA?

(And yes, I just checked, Z-AA is supported neither in Chitubox nor PWS!)

Bad news, fellow resinheads: Still no antialiasing on the Photon S, even with the latest FW! I just tried reprinting something where I could spot the x/y pixelgrid before. For the test I used the Photon profile in Chitubox with 8x AA (file does actually have AA, i did a visual check and the filesize is accordingly bigger) and saved to a .photon file, which the latest FW can now also print.. But I can still see the xy grid, new print is not postcured yet, but I'd even say it looks worse!.. apparently the greyscale images in the .photon file get converted back to monochrome again!
Anyone else done any testing? Or found another way to get AA on the Photon S?

Howdy all, I come for some advice and wisdom. I recently got a new motherboard for my Photon (the stepper driver died frying the entire board) After assembly I am having issues with the LCD and UV light interactions. When assembled and doing a print or UV test the LCD masks the correct shape for a split second and fully dissipates leaving the entire frame exposed to the light.

I wanted to test the LCD itself so I disconnected the UV light and the LCD works correctly, It performs the UV Test for the allotted time and I have ran some prints and it masks the images and changes layers correctly. When I connect the UV light mid test or print that's when it starts messing with the LCD, symptoms range from LCD not masking or exposing for a split then moving layers quickly or not at all.

I have done multiple firmware upgrades and downgrades from stock firmware to the anti aliasing firmware (the last good configuration for me) to the newest one.

I am not sure if its an internal electrical issue, since individually all the components work. I would hate it to be a motherboard since I just replaced it once.

The particular machine was purchased in July of last year before the fauxtons started rolling out ( i think)

I will post photos if necessary but I think I describe my issue accurately, any help is greatly appreciated.
