BIGTREETECHS2DW V1.0 Acceleration Sensor Module Compatible Klipper/BIGTREETECH Pi/Raspberry-Pi, High Resolution Tilt-Sensing Accelerometer

Great product, plenty of tutorials to get it set up. I recommend the manufacturers manual online, as well

This is such an improvement over the others for a number of reasons1. USB-C which means you can attach it to your Pi directly without having to solder and using ribbon cables2. Setup was very straightforward3. The larger mounting hole allows you to mount it on the extruder where the nozzle sits so you get a very accurate reading vs a mount on the side of the hot end that's not as accurate.I printed a mount for the Y axis of my Cartesian/bed slinger and left it attached to the bed I screwed in my sensor and ran the tests.I highly recommend either BTT version of this sensor

Primary reason for switching to Klipper from Marlin was to be able to use an accelerometer to configure the parameters for input shaping.It was a steep learning curve moving from Marlin to Klipper, but doubt I would ever go back, due to the huge conveniences found in Klipper.One thing that wasted more than a few hours, was the "error" reported by Klipper when you start the input shaping calibration. The first time you start the calibration process, an error is generated. Apparently, this is a known glitch, simply start the calibration process again, it works.I like the ease of using a USB C connection after reading hundreds of horror stories regarding mis-wiring accelerometers and breaking things.After installing the software and run a query on the device, if it isn't found, be sure to swap the USB C cable to a different brand or vendor, they apparently are not all created equal. Some cables work, some don't.

It works, takes a bit to setup but only takes about an hour or less if you know what your doing. Also improves print quality if you want to print fast. Kinda wished it came with a cable though.

The BigTreeTech S2DW V1.0 was extremely easy to flash, install and use to setup the Input Shaping on my 3D printers. I had never done this before and was a bit hesitant to try it. I used the BigTreeTech Git Hub to download the installation procedures following them and watching a couple of Youtube videos and it went smoothly. Now both my printers print quality and speed have improved. Well worth the effort and expense.

Works exactly as it should, I am using it to run 3d printer software. I was able to add a usb hub to add multiple ports without spending more on a bigger raspberrypi.

Works great, helped with tuning input shaping and eliminated much of the ringing I saw at higher speeds.

Fantastic, first one was lost in the mail but it was resolved.
