Eddy: USB Communication:Directly connects to the host computer such as Pi via USB, easy to install and configure. -fast and Ultra-precise: Utilizes millisecond-level eddy current scanning to precisely identify microscopic defects on the print bed and automatically adjust the height for fast and precise leveling. Advanced Temperature Compensation: Ensures consistent, precise leveling at all times, unaffected by temperature fluctuations. Effortless Installation in Minutes: The custom shell, designed to effectively negate external metal interference on coil detection precision, offers a predefined clearance zone for its coil, ensuring a straightforward, measurement-free installation that enhances both ease of use and accuracy. Ready for StealthBurner: Eddy series can be effortlessly attached to the TL-Q5MC/PL-08N location for quick and convenient integration.
