3Dtouch is compact and easy to apply due to its small size and simple structure. It works as an automatic bed leveling sensor, making information collection and firmware settings straightforward. Selftest alarm: An LED flashes to indicate a problem if one is detected during the selftest. Precision and reliability: The repeatable standard deviation is about 0.005 mm, providing accurate bed leveling readings. Low power operation: Very low power consumption reduces Joule heating and helps prevent thermal problems. Use in 3D printer setup: Use 3Dtouch for automatic bed leveling to simplify calibration and firmware configuration, improving first layer consistency. Routine maintenance and diagnostics: The selftest alarm allows quick fault detection, helping ensure ongoing sensor health without guesswork. Stable performance in demanding conditions: The low power profile minimizes heat buildup during long prints or in warmer environments, supporting stable bed leveling and print quality.
