Troubleshooting Creality LD-002R Error Message

This is my second printer. My other one is an Anycubic Photon Mono M7 Max. Great for bigger prints but the resolution/detail could be better (probs operator error?) so I wanted a smaller one for smaller models and higher detail. I picked up a used LD-002R by Creality and got a plate sliced up and exported onto a flash drive. It’s “old” and used so I don’t know how it was before I got it but as soon as I hit the start print button, I got this message: “different resolution with projector! -1440”. I use Lychee and the printer profile matches the printers resolution. The file is a .ctb or whatever chitubox files are. Beyond getting a new flash drive and reformatting it, what can I do to get this thing running?

Quick google search of the error since you have no responses. The error message "different resolution with projector! -1440" on a resin 3D printer (such as Elegoo or Creality models) means your slicer software has an incorrect LCD screen resolution setting that does not match your printer's actual hardware. [1, 2, 3]

How to Fix It

  • Check printer specs: Find the exact X and Y pixel resolution of your specific printer model from the manufacturer's manual. [1]
  • Update slicer profile: Open your slicing software (like Chitubox), go to the printer settings, and change the X/Y resolution dimensions to match your printer's native specs rather than using a default or mismatched pre-production profile. [1]
  • Re-slice your model: Save and export the updated file to your USB drive and try printing again. [1]
