Add a couple of seconds onto the base later

I think it needs more exposure

I use 90 sec for my base layers

Increase curing or exposure time for base

Might wanna increase the base layers as well.

My base layer exposure is set to 100, with 8 layers, I'm thinking by looking at how it separates i maybe need to add more layers

Temperature maybe?

a little help please I hear bottom, base layers, looking at the picture

would that be bottom exposure?

Exposure level, stl file, plate, resin, you’re not providing enough information

These are the settings I'm using, and I'm using elegoo grey resin

I would double check that you are still level and you cleaned your base plate.

This looks about like what I'm using, I would say room temperature might be a factor. I have had similar happen when it's cold.

Nathaniel Cooper normal resin or water washable?

I believe just normal resin, its Elegoo Grey

cold resin could cause that peeling

ive notice this happen to me when the resin is about 20-22 if i get it abou8t 24-26 its all good also the leveling is very important

I've been getting them on a few of my prints aswell tbh

yeah, i'm thinking its normal and i just never noticed them before since i haven't done a print this big that's flat

It's because the print is flat it's your layers

Nathaniel Cooper aye, even when I angle some of my stuff I still get em

Good undercoating won't see them

Ive actually printed that exact head, its setting on my desk at work. Has lines as well.

yeah, i assumed it was normal, just figured i'd check in case it was a sign of a larger issue

good to know

Where might I find those files? I've seen a few different models, of varying quality

PM me and I'll link the google drive to you

Done

Hey! Great to hear you’re getting good prints. It looks like you’re using the violet or pink plant based resin. I recently switched to plant based resin but my prints look a little goopy and im losing detail.. could you tell me your settings for prints? Thanks in advance!

Mine from a while ago, I havent had chance to reprint yet but I will as it's a bit warped but did for testing the scheme out

I'm just using eleegoo grey resin

Where's the file for the multipart warhound you can print on a photon ?

i have same problem then i increase the base layer exposure to 90 all problem solved except that remove the print is tough ? ?

PM me later today and I can share it with you, I got it in a google doc from someone else

Nathaniel Cooper dont suppose you could send me it aswell plse, I have 1 but it's abit dodgy, some of the parts don't load properly on my slicer

Yeah, just PM later, somewhere around 6ish PST I'll be home and at my PC then

Nathaniel Cooper I'm in the UK lol, not sure when PST is lol

Pacific standard time, so like in 6-7 hours from now, lol

What's your bottom layer exposure?

Raise base layer time, too low ambient temperature?

Exposure level would be the next adjustment. also temp of the room and making sure the resin is mixed before starting the print

These are my current settings

Its inside so it shouldn't be ambient temperature I'd think, but I hadn't thought of mixing the resin between prints, I did shake the bottle before adding more though

my bottom is 100. Nothing peels

Up your bottom exposure to 90

Yeah I'm seeing people having their bottom exposures really high, I was just going off what I saw on the google doc,

I'd suggest taking the build plate apart and cleaning the ball joint. Resin in there makes it super easy for the plate to shift during printing. Which looks like what you have.

What should I clean it with? And how can I tell for certain if that's the case, it seems to be level and I haven't had any issues with it before

Use whatever you use to clean your prints. I use IPA.

You can put the plate back on, without the vat, and check the level with a piece of paper. See if all 4 corners have the same resistance. If they do, you're good. If not, take that sucker apart. It's easy, and only takes a few minutes.

If you fill the resin above the top of the plate with the 4 head heads showing, then you have resin in your ball joint.

Maybe adjust closer your first layer height can help too

Nathaniel Cooper 100 seconds is what I also use, since i started to use it i haven't last anything that wasnt down to my own stupidity

Sometimes when you tighten up the ball it moves slightly to one side, in the rare occasions I have to level I have to hold down the right side of the plate when I tighten. It looks like the side that lifted is slightly higher than the other

I usually don’t chime in much anymore but I got the photon when it first came out full price. I was one of the first to take out the glass and print directly on the lcd with the wanhao and also modified my photon to do the same. I wanted better resolut ion at the time and the resins available weren’t as good as they are now since I used it for jewelry. Now two years later there are so many resins out. I’ve ran into every problem you can think of few years back. I agree with one of the comments wiping down with alcohol after every print. But also taking a razor blade to create slashes like this in all directions. It gives the resin exposure time to sink into the base and stick. Of course that would depend on your resin etc. hope that helps. Another thing about the photon is that the z is kind of at an angle when it goes up and down even after calibration. I upgraded mine using this

I’m not sure if Bluecast still carries the kit. But it’s helped with the z wobble for the table. Calibration is the best it’ll get to 0

Just upped my exposure time and checked the print after a bit and it seems to be sticking just fine now, I'll know for sure in a few hours when its done

I used to be on all of the 3d print groups. I’m no longer active. But you can pm me for help. I used to answer a lot before my health issues and having a baby. Goodluck

I started cleaning my build plate with acetone between builds. That seemed to help

You have large flat surfaces parallel to the build plate. That means it submerges, resin goes over the top, and then it tries to pull out and all that thick liquid resin on top of the print has nowhere to go. Which means it is pulling all that resin out, doubling or tripling the weight of the print.

Tilt your model. Don't have big flat surfaces pointing at the build plate.

How cold is the room you are printing in? Cold is really bad for making prints peal like that

Preheating the resin could surely help

Suction

This started happening about a week before my LCD started going out on me. Next will be crazy layers. just printing in non-model areas. It really sucked. I had to replace the LCD.

I know you said that the build plate is leveled relative to the screen, but is the whole printer level? I found that the printer needs to be pretty close to level for best results.

^this ?

Jimmy Goldsmith can you link where to find this?

Let me make this post public for everyone

Adam Zed posted. Now I remember why I don’t get on much. People trying to debate etc. But I’ve posted a thread with the link check it out and good luck.

Likely partially sticking to FEP
