We aim to take the guesswork out of buying 3D printer parts and components.

We love 3D printing because of the unique nature of open source design philosophy and there’s nothing better than printing from a machine you’ve brought to life - just like the Voron 3D printer.

Description

Mounting

A small part can to be printed for mounting the accelerometer PCB onto various toolheads:

If a compatible mount is not available, or if you want to design your own mount, please refer to the following drawing:

Alternatively, you may also choose to mount the accelerometer using double-sided tape.

Wiring

Wiring the input shaper tool is simple. First, attach the FFC ribbon cable to each PCB: carefully pull up the black tab on the FFC connector, then insert the FFC ribbon cable and push the tab back in. Take care when pulling up the black tab! It is fragile and will break if pulled with excessive force. To make sure the polarity of the ribbon cable is correct, refer to the following picture:

Check that the blue side of the FFC cable is oriented correctly

Now install the smaller PCB onto your Raspberry Pi as follows:

Mounting Orientation for Version 1 of the ADXL Pi PCB
Mounting Orientation for Version 2 of the ADXL Pi PCB

Note that Version 2 of the Pi PCB integrates a screw terminal for the 5V Rail of on the Raspberry Pi. This screw terminal can be used to supply power to the Raspberry Pi instead the USB port (Micro on RPi3 and Type C on RPi4).

Software Installation

Before you can start running input shaper calibration, you need to install a few software packages on your Raspberry Pi. Refer to the software installation section in the klipper input shaper documentation.

Checking the Setup

To test everything works correctly, run the command ACCELEROMETER_QUERY in your klipper console. If everything is correct, you should see some measurements from the accelerometer on the console output.

Calibration

The easiest way to perform calibration is to simply run the command SHAPER_CALIBRATE in your klipper console. Be sure to read the corresponding section in klipper’s documentation for more details and advanced commands and settings.
