You must use the adxl. We use an inexpensive acceleration sensor (accelerometer) of type ADXL345 for the X and Y axes to measure the resonances. #minimum_z_position: 0 # The minimum Z position that the user may command the head to move # to. Mounting # acceleration on XY moves than Z moves (eg, when using input shaper). Depending on the board layout and used components a few things should be considered when connecting the About installing the ADXL345 accelerometer to calibrate easily input shaping for an Artillery Sidewinder with Klipper firmware. Rather, I'm going to discuss things I've experienced and how I went from crappy input shaping to really good input shaping. The Raspberry Pi (RPi) Pico offers a convenient and cost efficient way to create a portable resonance measurement device that can be used across different Klipper printers. 1. It can be installed on any Klipper machine and is not limited to those using the full Klippain. See real results from Klipper resonance compensation/testing with accelerometer data. Klipper claims that the EI input shaper algorithm works best for bed slinger printers such as the Ender 3 and Prusa. Convenient Input Shaping, run input shaper calibration at anytime with an onboard accelerometer. With a simple ADXL345 accelerometer, basic wiring, and Klipper’s tools, you can dramatically improve surface finish, dimensional accuracy, and reduce ghosting—even at aggressive acceleration settings. Note that using ADXL345 requires some soldering and crimping. It's the only accelerometer model supported by klipper.

Input shaper (IS) This calibration follows the Klipper documentation steps but they are simplified for the V-Core 3. Enhance your printing experience now! Getting Started While not required Input Shaper is a great tool to help with printing faster and getting rid of "Ringing" or "Ghosting" in your prints. 2. Enabling an ADXL345 accelerometer, as with CANbus with enabling the option spidev1_1 our system will enable access to the SPI port of our Pad 7. You can fine-tune further by running prints with higher acceleration and observing results. Best used for cancelling out vibrations over a narrow range of resonant frequencies EI , 2hump EI, and 3hump EI E xtra I nsensitive input shapers. (iirc, it's not just an implementation matter, I believe the mpu6050 doesn't actually have enough bandwidth to keep up with what input shaper is doing) Measuring Resonances Klipper has built-in support for ADXL345 accelerometer, which can be used to measure resonance frequencies of the printer for different axes, and auto-tune input shapers to compensate for resonances. 1).
