We got this to use with our printers, but now we're upgrading and don't need the pad. It was never set up, so it's basically new.
"The Creality Sonic Pad is a Klipper-based control screen for 3D printers, featuring a 7-inch touchscreen that boosts print speed and quality by offloading processing to its powerful 64-bit system, allowing faster, smoother prints with reduced vibration through input shaping. It simplifies using Klipper firmware for most FDM printers (especially Creality models) via USB, offering remote monitoring, model preview, and control over up to four printers, making high-speed printing accessible without complex DIY setups."
