Hello everyone! As it says in the title, I very recently bought my first 3D printer, the Elegoo Mars 4 Max. Two days ago, I did my first test print, and it came out pretty good (although maybe a bit too hard, but details looked sharp). The only problem was that I somehow got an error message in the end ("error printing file data exception"), but the print seemed to have finished, so I didn't really worry too much.
I was pretty happy, so yesterday, I tried printing some more. I tried to print some exposure test files (3DRS starship https://3drs.com/pages/3drs-starship-resin-calibration-test and Cones of Calibration https://www.tableflipfoundry.com/) after slicing them with Chitubox. No error message this time, but the prints failed very early. Can anyone help me figure out what the problem might have been?
Here's some additional info:
For the first test print, I did not do any slicing or calibration, I just used the .goo file that came with the printer.
Cleaned the build plate with IPA and paper towel after first print
Did not clean or empty the Resin Tank after first print
Did not level the build plate again
24 hours between first and second print
I stirred the resin a bit before the second print, but maybe not enough
I don't know what the exact temperature was yesterday, but it was still pretty warm.
In Chitubox, I changed the settings to my printer, then downloaded the PDF with the settings for my printer/resin combo (Standard 2.0 grey) and put them in. I then dragged the .stl files into the window and sliced the files, exporting them as .goo files. I then copied the .goo files onto the USB stick and plugged it into the printer.

I don't have a printer that does tsmc so apologies if i'm misunderstanding but you could try increasing the first stage bottom lift distance? Maybe it's not peeling off the fep before it hits high speed. Otherwise you could try sanding your build plate lightly, adding ptfe lube to the fep (haven't tried this yet but other people say it works), or last resort increase base exposure time.
No worries, I had no idea what TSMC even is and was confused by these settings having two different numbers, but now that you've mentioned it I was able to Google it and I think I understand now.
Anyway, thanks for the suggestion and for helping me learn, I might try that!
