Input Shaper Calibration for Klipper: ADXL345 Accelerometer Method

#InputShaper In this video, I have tried Input Shaper calibration for Klipper firmware, using ADXL345 accelerometer module on a heavily customized Ender 3 Pro 3D printer. Using an accelerometer, you can automatize the acquisition and analysis of the vibration, which is crucially important for Klipper to apply its input shaper functionality. This is a video log where errors and pitfalls I met in the process is being recorded with minimum editing. Which means, if you want to follow this as a guide, I assume you have installed Klipper and Octoprint by yourself and are comfortable with the process. Also there are some electronics skills involved, including soldering and crimping connectors.
