KUSBA: Klipper USB Accelerometer
Easy Input Shaper Calibration
KUSBA is a PCB designed to make Klippers input shaping much easier by simplifying the wiring and config for measuring resonances. It is an MCU and the ADXL345 accelerometer on one PCB. You just need this PCB and a USB C cable, no complicated and unreliable SPI wires!
Compatible with every 3D printer running Klipper and has an available USB port. Comes with firmware pre-flashed so you can just edit your Klipper config, connect the KUSBA and start measuring resonances.
