Input Shaper for VORON V0.1

WHAT IS THIS?

Input Shaper Board is designed for VORON V0.1 3D Printer exclusively. All the tiny components placed on the board symmetrically. And the board thickness is 2.0mm, make sure the the Strain Relief is strong enough.

HOW TO MEASURE 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. Note that using ADXL345 requires some soldering and crimping. ADXL345 can be connected to a Raspberry Pi directly, or to an SPI interface of an MCU board (it needs to be reasonably fast).

When sourcing ADXL345, be aware that there is a variety of different PCB board designs and different clones of them. Make sure that the board supports SPI mode (small number of boards appear to be hard-configured for I2C by pulling SDO to GND), and, if it is going to be connected to a 5V printer MCU, that it has a voltage regulator and a level shifter.
