I've recently gotten into Resin 3d printing with a refurbished Elegoo Mars 1 but I've run into a weird bug where the printer would not expose any resin to the LCD.
I tested it by taking off the build plate and basin and looked at the LCD when it was exposing the layers. I've tried updating the firmware and tested about 20 odd prints of various sizes and detail. With those I saw that prints with large individual layers essentially stopped the LCD entirely (The exposure would flash on the LCD for a second then the LCD would not turn on again until I completely restarted the printer). What is more bizarre is that the first test print I did worked perfectly and still does for some reason (which was the tugboat and a random miniature).
For specific printer details I have an Elegoo Mars with the C type motherboard. There are no burn marks on the wiring or circuits and the LCD screen was replaced recently with a brand new one. And nothing is misaligned or unplugged. I even double checked that the LCD was still functional with the test exposure tools on the printer.
From my observations it is a data streaming issue with how it is connected with the USB drive. But that is a software issue that I am not capable of knowing.
Any ideas on what could be wrong or if this has happened before?
EDIT: Discovered that the Firmware needed to be updated to the latest version. Also, after testing out several very different print files the original print file that was having this issue was corrupted in some way as rebuilding it and printing the new version more or less worked. I also did another go around with cleaning everything and making sure that both the plate was level/tightened, FEP replaced, and that there was no IPA leftover on either.
