LDO Unicorn Chasing Kit by Reth - ADXL Nozzle Resonance Testing

The Unicorn Chasing Kit is a resonance compensation toolkit centered around two core components: the Rethonance Nozzle, a V6-compatible nozzle with a built-in ADXL345 accelerometer and the Rethonance Hub, a magnetic, bed-mountable board that consolidates connectivity for ADXL sensors, motor thermistors, and a GPIO extension port — all over a single USB connection. Together, they provide a convenient way for users to precisely measure resonance at where it actually matters - the nozzle.

An ADXL where it matters most

The Rethonance Nozzle is a V6-style nozzle with a built-in ADXL345 accelerometer, featuring a non-ZIF (press-in) FFC connector. A thermistor is integrated into the nozzle which, in conjunction with the recommended Klipper configuration, protects the ADXL chip from overheating. The nozzle is compatible with any hotend that accepts V6-style nozzles.

Magnetic Magic

The Rethonance Hub was developed to address a common inconvenience: the need to physically reposition a printer in order to connect an ADXL board. The solution is a dedicated board with a long USB cable and a magnetic mount, allowing it to be attached directly to the print bed for easy access.

The Rethonance Hub features two press-in FFC connectors, both pin-compatible with either the LDO Rethonance Nozzle or E3D Revo Rethonance Nozzle. Additional features include four thermistor inputs — useful for monitoring motor temperatures on high-end AWD setups — as well as a third SPI port and a GPIO header for expanded connectivity and customization.
