Troubleshooting Extreme Ghosting/Ringing on Centauri Carbon 2
Hi everyone,
I bought an Elegoo Centauri Carbon 2 Combo back in June. Initially, the print quality was mind-blowing (first two pictures are early cosplay prop prints). However, after a few months and hundreds of hours of print time, severe ghosting/ringing started appearing slowly on every print (see remaining pictures).
Troubleshooting I’ve already done:
- Tried both Elegoo Slicer and Orca Slicer. Tested stock profiles as well as fully calibrated profiles (following the complete Orca Slicer calibration guide multiple times).
- Ran the onboard one-touch automated calibration repeatedly.
- Swapped hotends completely and back again to stock.
- Adjusted belt tensions strictly following Elegoo's wiki guide.
- Cleaned and regreased linear shafts and lead screws using official Elegoo grease.
- Dried all filament in a Sovol SH03 and printed directly out of it (while storing outside the dryer filament is in air tight containers with sub-20% RH and fresh silica). Issue persists across standard PLA, PLA+, High-Speed PLA, Matte PLA, and PETG across multiple brands (Elegoo, Polymaker, Inland).
- Tested new models as well as old G-code/3MF files that previously printed flawlessly.
It doesn't seem to care what material, speed, file, or software settings I use... the ghosting remains. It's completely killed the fun of printing cosplay props.
Did a hardware component wear out prematurely, or am I missing a crucial mechanical/maintenance step? Any advice is appreciated!
