Learn input shaping and how to get better prints while printing faster. Get rid of ghosting and ringing to achieve high quality models! Klipper offers the use of USB accelerometers, the process is simple and easy! Learn how to read an input shaping graph, and which input shaper is best! Currently Marlin firmware only offers manual input shaping, but the input shaping concepts covered in this video will still apply! In this video I am using Triangle Labs accelerometer and it comes with everything you need to perform this calibration. The Input Shaping article on my website details the process with a KUSBA accelerometer!

—Commands—
Configure host device for auto input shaping:
sudo apt install python3-numpy python3-matplotlib libatlas-base-dev
-
~/klippy-env/bin/pip install -v numpy

Build firmware for TriangleLabs ADXL:
cd ~/klipper/
make menuconfig
*the setup for my ADXL STM32 variant*
[*] Enable extra low-level configuration options Micro-controller Architecture (STMicroelectronics STM32) Processor model (STM32F103)
[*] Only 10KiB of RAM (for rare stm32f103x6 variant)
[] Disable SWD at startup (for GigaDevice stm32f103 clones) Bootloader offset (No bootloader)
Clock Reference (8 MHz crystal) ---x
Communication interface (USB (on PA11/PA12))
USB ids
(!PC13) GPIO pins to set at micro-controller startup
****
Create the firmware:
make

Identify the address of the ADXL:
ls /dev/tty*

Flash firmware:
stm32flash -w out/klipper.bin -v -g 0 /dev/ttyUSB0 [amend the USB #]

Check Accelerometer:
ACCELEROMETER_QUERY
MEASURE_AXES_NOISE

Run Tests(Manual computation):
TEST_RESONANCES AXIS=X
TEST_RESONANCES AXIS=Y

Run Test ALT (auto computation and addition):
SHAPER_CALIBRATE AXIS=X
SHAPER_CALIBRATE AXIS=Y

Compile Test info:
~/klipper/scripts/calibrate_shaper.py /tmp/resonances_x_*.csv -o /tmp/shaper_calibrate_x.png
~/klipper/scripts/calibrate_shaper.py /tmp/resonances_y_*.csv -o /tmp/shaper_calibrate_y.png
