Could anyone tell me what I am doing wrong? The print seems stuck to the build plate well enough, but also sticks to fep. Any help greatly appreciated.

Might not be leveled good enough so that the suction of the FEP is too high for the print itself to stick to.
Or supports are too weak to combat the suction.

This is happening to me 80% of the time. Will be happy to know the answer too

The skirt is stuck well enough, it's breaking at the points of attachment. I guess I could increase the size of the contact. Is there anyway to lubricate the fep?

You should probably hollow it, and don’t forget to put vent holes
Jarin Udom

And also add some heavy supports to keep it from pulling off

I have hollowed in the past - I think they're more prone to cracking

Sure if you don’t do it right, you need to make sure you have enough vent holes so that you can get all the internal resin out when you clean it (and reopen the holes with a drill if they plug up)

Or just add some strong supports haha and you won’t have to worry about it
Allison Janssens

Hollow, or stronger supports. I strongly suggest you hollow it, make sure the vent holes are on the right side so the resin can flow out of the cavity. The model is so thick it's a huge waste of resin to print it solid.

i use auto vinyl spray - and vibe afterwards . Dont know if it is recommended in general. But my prints come out great

make tip of the supports thicker. and let them penetrate the geo a bit deeper.

yeah, greg is great. but his thinnest support tips are 0.12mm thick. thats crazy thin. he figured it out, but it doesnt mean that his settings will work for others. different resins, different exp times...
David Devonport

It absolutely does work for all. It's not enough to copy his settings, you have to follow his workflow too.

Think about how this is printing. Your supports and raft are printing fine. The first bit of the actual model to get printed is the feet, but that's failed. So the supports were not strong enough to overcome the suction of the fep. Strengthen the suppo
rts there. Hollowing helps reduce the suction by cutting down the surface area stuck to the FEP so you can use fewer supports, but you could print this solid if your supports were stronger.

I have a product called J wax. It's a spray on wax release agent. I guess it would work but I'd like to know in advance. Guess I'll just go for it......

It works, though. And you can use his supports as a sort of exposure calibration tool. If they fail, up your exposure by 1s til it fixes it. If they start to clump, down exposure by 1s.
He's currently doing all the presupported stuff for the Artisan
Guild Patreon, and I've been printing perfect dwarves all month. EVen just pulling apart the STLs he provides for these I've learnt so much.
My settings are Original Photon, Elegoo Grey/Anycubic Grey, 60s bottom exposure, 8 layers, 9s standard exposure. Perfect every time. And the 0.12mm light supports still support what they need to, but they leave no marks when you pull them off.

You should be using pursa for supports

what is it that makes pursa better than chicubox?

Looks like you need to put heavy supports where they will not be seen (Bottom of the feet and the crotch) this give you a solid pull point to break the suction. If the feet stick to the FEP as you seem to be doing then the whole model will likely fail.

His supports are amazing but not foolproof. Run his supported filed through the file validator. Lots of islands. His workflow is what is important. His settings are a great place to start and work out what your specific settings will need to be. N
ot knocking his videos as they are what taught me how to not get shitty minis with pockmarks everywhere and failed prints but you can't use his settings verbatim and the presupported files from AG are not foolproof.

I don't think you need to lean the model, straight up and down. put a hole in the feet. Chitubox supports are good enough should be an easy print for you.
Abdul Hanan Ismail

This used to happen to me quite a bit until I set supports to Heavy in Chitubox. Never had a problem since.

Always use heavy supports for large prints.
Hollow out the model, add holes. Make the depth penetration to what ever thickness you hollowed it out to.
Fred Breton

Increase tip contact depth
Lee Fletcher

Yeah, the short answer is your support tips are too small/fine. If you're using Chitubox, the default light supports are worthless.
Jason Pedersen

this does nothing really. It increases the contact diameter marginally, but once a model is sliced, it's all on or off pixels. Better to up contact diameter manually, or as stated above, heavier supports, hollow, and adjust exposure times.
Fred Breton

try it, this help for tiny island to grow, i use tip size of 0.12 to 0.3.
Jesper Hvid
2020-03-30 22:17:11
Cannot see it, so asking. Look like alot of light support. Did you use any heavy to anchor it to the buildplate?

I make mine smaller than the default and do just fine
Jason Pedersen
2020-03-30 22:19:02
Fred Breton
that has nothing to do with contact depth though. I use tiny contact diameters for small islands too. How deep a contact goes into a model is irelevent.
Alexander Bayerdorffer
2020-03-30 22:20:43
Everyone saying the tips are too small does not make sense I make mine super thin even across different resins. Run an exposure test. and also hollow the print and add holes. Probably too much suction

Every one of them fails on me, even when the rest of the print comes out fine the connections from the lights are just gone.
Alexander Bayerdorffer
2020-03-30 22:27:06
Sounds like an exposure issue then or a suction issue. Perhaps your fep is also not tuned right. Too much suction could mean you need to hollow. Even if you tuned your fep after the first print and maybe even the first few it will loosen up and then se
ttle in. And exposure while you think you might have it right my just be a touch too low. I have made supports as small as chitubox will let me and across multiple resins and prints with no issues.
Christopher Fugate
2020-03-30 22:29:02
Its not suction or the fep. Medium supports work fine. Everything prints fine, as long as they're not Light.

I know, and I appreciate the thought, just letting you know I've gone through everything I can think of short of beefing the lights back up. I might try switching them over to a beefier tip type anyway.
Fred Breton

Jason Pedersen
your sketch is right now you can decrease the tip size to the one you want at the contact point, and the extra depth will help you
Corey Ardwin
2020-03-30 23:07:34
I’ve had this same problem. I changed the support tip penetration from 0.25 to 0.35 on my small supports, and it fixed everything.
Jason Pedersen
2020-03-30 23:10:24
Fred Breton
the depth doesn't help at all. Once a model is resin, it's resin. The support doesn't stick into the model, it becomes part of the model. The only thing that matters is the actual contact surface made with the model.

You're probably just underexposing, either enlarge your supports or up your exposure.
