Coming here for some help as I am having an issue with my Elegoo Mars Pro. Lately all of my prints have been coming you like wet noodles. What I mean is that after they print I can bend them all over the place without breaking. This is pre curing of course but not normal.
I have replaced the LCD, FEP, leveled and releveled, bought new resin (just in case of a bad batch).
In addition, I have played with the exposure times and settings to try and see what I could find.
Here is my findings. I Have to now increase my bottom exposure time to 70 and Exposure time to 16 to even get a file to print at all and they come out super soft.
I am worried that my bulb/lens is going out. I looked at the light when doing the test and cannot really tell if it is dim or not. I don't have holes or blank spots and it doesn't look like it dims at any location.
I have had the machine for 2 years and have used it somewhat frequently. I couldn't tell you the number of hours.
I use ELEGOO 3D Printer Resin LCD UV-Curing Resin 405nm Standard Photopolymer Resin for LCD 3D Printing Translucent 1000g
Any suggestions?
Thanks for any help.
Interesting problem !
Does the resin harden when exposed to sun or curing lamp? (I assume you are shaking the bottle well)
The only time I've seen anything similar is when I was experimenting with dyeing the resin , excessive pigment/ink softened the resin.
Can you see if all the all the UV LEDs are actually alight? (or the whole of the cob is alight, if single device)
I suppose it could be the LEDs dying , they do have a finite life or maybe the driver is failing ? (anything obviously hot on the driver board?)

I do shake the bottle before each use and have not added anything. I have tried multiple bottles to see if the resin was bad but it is happening with both.
To me it looks like the entire build surface lights up but I can't really tell if it is full strength.
I have not noticed anything overly hot on the driver board but will check again.
Not sure how much a replacement UV lamp costs and I can't seem to find one online either.
