The ExADXL breakout board makes it easy to mount an ADXL module, or a number of ADXL, to a Raspberry Pi Pico. This can be a fashionable strategy to including additional resonance measuring devices to a Klipper-controlled 3D printer.
If the above is unfamiliar to you, Klipper is an open-source 3D printer firmware that’s quickly being adopted within the 3D printing group. It’s a really slick firmware with far too many choices to dive into right here nevertheless it’s properly value trying out and experimenting with. One facet that allows some important will increase in printing pace and high quality is that Klipper can measure resonances in your machine and tune the machine based mostly on its readings. A preferred path to enabling that is by including a second MCU and an accelerometer. The MCU needs to be moderately succesful and quick and as such the RP2040 powered Pico is a strong alternative.
The ExADXL makes this actually easy to arrange with a mounting PCB for the Pico and quite a few connectors for including a number of ADXL modules, virtually all attainable choices for which can be found on the product web page. You can begin with simply the naked board, or there are alternatives for extra {hardware}. Optionally, you possibly can have a whole unit with the Pico and the ADXL put in, flashed and examined.
If you happen to’ve obtained a 3D printer that might use a breath of contemporary air, then the Klipper firmware and the ExADXL breakout are positively value looking at!
