So, I just got the Saturn 8k and I'm having trouble getting supports to stick.. Here's the test:
I used the lifting speeds recommended on the Bernie post, and it seems like the only way to get them to connect is by overexposing things >.<
Any thoughts? Could my fep filter be too tight/lose or is this a settings issue.
Settings
Printing at 27 c room temp with the Elegoo Water Wash in Gray

2.25 expo went better, the "thick cube" is in place nicely, the other one is holding for dear life, but the rest of the test is very clearly overexposed right?

lets see the support settings
if your getting supports detaching with these settings then the issue is either bad resin of the support contacts are too fine or the surface are of the layers is too extreme for the supports

So yea I managed to print a presupported lilith bust fine, but the base didn't print, HOWEVER, I managed to print it with my own supports (heavy) & bigger holes.
I'm gonna try a print from a "trusted" creator now that I know SHOULD work to see if the supports still break
This is the presupported base that would not print
And this is the one that did print
(failed print had 3 holes, mine did 5)

there is NO SUCH THING as a TRUSTED creator, they can not know what resin, printer or settings you are using
it is 1000x better for you to take the time to learn how to support your own models
its not hard
only a few rules
always tilt the model, never have any surfaces or straight edges paralel to the build plate
use auto support in chitubox with medium supports then manually add some heavy supports at the low points to do the most of the lifting, add some light supports to hold fine details
just remember resin printing is a game of reducing the lift forces
each new layer has a surface area that is stuck to the FEP, the rest of the model and the supports holding that model need to be strong enough to peel that new layer off the FEP

Yea I gotchu
I guess my thinking when saying "trusted creator" is someone that would probably adhere to the rules you mentioned
I guess I still don't understand why the damn test model cube won't stay, even at speeds lower than the recommended here. without getting overexposed >.<

its elegoo water wash
i do have anycubic water wash too (that i used on my m2) and it was fine tbh
Might go for the Sirayatech waterwash
elfin anchor
siraya tech has the best reliability
elegoo WW is a mixed bag, often people have had trouble with it, one guy had the most amazing detail prints with it
but on a whole its reliability is hit and miss
normal anvil
Yea might as well bite the bullet, the price point is a little up there for me in comparison (mostly due to fking shipping)
I put 2 character heads next to each other 1 with my supports 1 presupported, mine printed.
But again I had to do fairly heavy supports and it's overexposed... At this point Ive done so many tests that I'm almost glad I'm running out of this specific resin
elfin anchor
in general water washable resin will never be as good as regular resins, even the ST resin still needs liike 30% IPA in the water for good clean
however the ST resin is 100x more reliable than the other brands
these are 2 resin printed RC planes I made using ST fast mixed with ST Blu
normal anvil
Yea that makes sense
Well that's new, it detached from the plate..
Like, pick a struggle man, are you gonna be underexposed overexposed fail supports or detach from the plate..
Increased bottom layers and exposure time, let's see how that goes...
elfin anchor
45sec bottom exposure is abut the best you can do, any longer will not make a dif
but im seriously starting to think you just got a bad batch of goo
normal anvil
Yea same, might try some old(ish) anycubic one that I still have that printed completely fine
For water wash, do u still recommend ST?
Sidenote, success with significantly bigger holes at the bottom and +2 btm layers +10 btm layer exposure
elfin anchor
the things I would recommend is to stop mucking about with the water washable stuff
just grab some ST fast and set up a simple 2 stage IPA wash
cleaning with IPA is simply far better
normal anvil
I know it also dries quicker which makes curing not leave those shiny spots but
i just idk... the whole process of wash and cure, change alcohol every so often, have sticky fingers cause gloves can't do their one job
last time a year-ish ago i did and after i was done with a few prints i never touched resin 3d printing again cause i was like nah too much fuck this
that being said, the biggest difference so far does seem to be making sure i do my own supports & slightly bigger than id normally do holes
So yea you were definitely right on the fuck "trusted" anyone
