Proprietary "Walled Garden" – Hardware Held Hostage by Broken Software
I am writing this to warn potential buyers about the "locked" ecosystem of the Elegoo Centauri Carbon 2 (CC2). While the hardware is solid, the software implementation is anti-consumer and currently unreliable. I have been plagued by intermittent connection failures between the printer and the Elegoo Slicer. Because Elegoo has provided zero communication about their server issues, I was misled into thinking my machine was faulty. I performed a factory reset, wasting hours of time and losing all my print history and calibration data, only to realize the problem was on their end. The "Locked Down" Design Flaws: No Network Access for Other Slicers: Unlike almost every other modern printer, the CC2 has no hosted web interface (Mainsail/Fluidd). This means you cannot connect industry-standard software like OrcaSlicer or PrusaSlicer to the printer over your network. You are 100% forced to use Elegoo’s proprietary software. The "Cloud" Bottleneck: Even if your printer is on the same local network as your PC, the Elegoo Slicer relies on their cloud servers to communicate. When their servers fail, your PC slicer disconnects. The "Catch-22" Fix: You can switch to "LAN-Only Mode" to bypass the cloud, but doing so completely disables the mobile app. You shouldn't have to choose between a stable PC connection and using the advertised phone features. Filament Restrictions: They have intentionally disabled non-Elegoo branded filament profiles in their slicer to force you into their own ecosystem. It is unacceptable to sell a "pro" machine and then leave customers in the dark when your mandatory cloud infrastructure fails. Elegoo needs to open the firmware for local network control and stop the anti-consumer filament locks. I cannot recommend this machine in its current state.
