BIGTREETECH BTT Eddy – High-Precision Eddy Current Bed Leveling Sensor for Klipper The BTT Eddy is a cutting-edge eddy current probe designed exclusively for Klipper firmware. Using advanced eddy current sensing technology, it delivers ultra-precise, contactless bed leveling and Z-homing without the limitations of traditional inductive or mechanical probes. Weighing only 6g, the BTT Eddy adds virtually no extra mass to your toolhead, making it ideal for high-speed 3D printing. It achieves remarkable 0.5μm (0.0005mm) standard accuracy and can complete full bed leveling in as little as 20 seconds — 6 to 9 times faster than conventional sensors. Key Features: Eddy current sensing technology for non-contact, high-precision measurement Ultra-lightweight design (6g) – minimal impact on print quality and acceleration Exceptional accuracy: 0.5μm standard error Extremely fast bed meshing (as fast as 20 seconds even on large beds) Built-in temperature compensation for stable performance Supports Z-homing and auto bed leveling Easy integration with Klipper (simple configuration via printer.cfg) Multiple variants available: Eddy Coil, Eddy USB, Eddy Duo (USB + CAN) Compatible with metal spring steel build plates (recommended for best results)
