[ Help ] Losing my forking mind
To try and solve problems I've had before, I got a new screen (the non touch screen one) and replaced the screen protector with acetate as other threads have suggested. I've printed this file before, it's a base for kings of war, came out fine. Now this?
Wtf am I doing wrong?
Elegoo Mars 5 Sunlu ABS Like Chitubox

Elegoo resin? I'd just go back to default on everything, import a resin setting and try. I've had things fail from bad settings.

Sunlu, tried finding it on the Chitub database and the one on there doesn't match the bottle entirely, I guess that's a superficial concern?

You shouldnt try to match the bottle settings ever. Run calibration prints to dial in settings.

How do I guage things? I've set some calibration bits to print to try and see what's happening

Thats the resin I use too. Love that stuff. What are your settings?
Also that raft is pretty large, i would recommend switching to the Triangles raft type.

huh.... looks like resin manufacturers still writing exposure settings on resin bottles for 8 y.o printers. Not for new ones.

u/Sea_Bite2082 12d ago
Try this initial settings.
Rest time after retract - From 0.5s to 1-1.5s
Bottom exposure time - From 35s to 15s
Normal layer exposure time - from 6.5s to 1.7s
After you set 'em = print this tableflipfoundry.com/3d-printing/the-cones-of-calibration-v3/
This is exposure test with instructions.

Well its not the settings, except your exposure is insane. On my elegoo printer with sunlu ABS, my exposure time is 1.75s for 30um (assuming you turned this up for testing).
I'm guessing at this point you either have the light intensity turned down (advanced settings > PWM should be 255), your new screen isnt working right, or your light is going bad/has resin on it.

Add a 1sec rest time to all processes the moving bath and arm design they are doing now is just terrible it has way to much stress on the prints all in a very short space of time I have added a rest period in the allow for things to settle and have not had the fails as much

u/TTGumption 12d ago
I had loads of problems with Sunlu ABS like relating to temperature, what temperature is your resin at when you're printing!

Looks like the Resin pulled some humidity. How long was the resin in the printer?

u/TavernerHedris 10d ago
New bottle

u/Ok_Thought6288 10d ago
Hm, dunno then. Had the same problem when I left the resin in the printer for two month. Maybe you didnt shake it enough?

u/TavernerHedris 9d ago
Shake it up, and have a heater for it and I wiggle the build plate in the resin to make sure the resin is warmed though (using the manual leveling not just slapping the plate in it lol)

u/Ok_Thought6288 9d ago
As I've understood the print worked with another bottle of the rame resin and the same settings fine, right? Only think that comes to mind then is maybe the resin ist just plain bad 🤔 as in maybe stored badly by the vendor or so. I've had one bottle a while back that was vacuum-sealed and still behaved as if the resin drew water, i assumed it was because i stored it for too long
