KUSBA Mounted on a 3D Printer

- Connects with an USB C cable, no more complicated and unreliable SPI wires
- Compatible with every 3D printer running Klipper and has an available USB port
- Open source hardware
KUSBA: Klipper USB Accelerometer
Easy Input Shaper Calibration
KUSBA is a PCB designed to make Klipper's input shaping much easier by simplifying the wiring and config for measuring resonances. It is an MCU and the ADXL345 accelerometer on one PCB. You just need this PCB and a USB C cable, no complicated and unreliable SPI wires!
Compatible with every 3D printer running Klipper and has an available USB port. Comes with firmware pre-flashed so you can just edit your Klipper config, connect the KUSBA and start measuring resonances.

There are a lot of great YouTube videos and instructional articles about how to use these to optimize input shaping and eliminate ghosting so that you can increase print speeds and accelerations. Most printers also Have 3-D printable adapters on the common model websites.

My overall experience in using the Kusba have been pretty smooth. Went to their GitHub page and followed their instructions and got it all working in just a few minutes on my Sovol SV06 Plus. (Would recommend looking up mounting solutions ahead of time)The only downside I've found so far, and I'm not too sure if it varies by each pcb, but I have to reflash the Kusba everytime I unplug it and plug it back in to use again. Albeit, it's easy to redo the process to get it working again, but I could see people thinking it's somehow broken, or tedious in having to reflash it over and over again.

As a beginner in 3d printing.. it did take me a whole day to get this to work...i could not find answers anywhere. I check their discord and figured out my printer.cfg file had some code in there that did not need to be in there.

Phot shows before (furthest from camera) and after using this to tune out the resonance of my Klipper driven Ender 3.Was an absolute snap to mount and use after printing mounts, whole process of tuning was about 30 minutes.Instructions were very good, combined with Klipper documentation.If your printer is a bed slinger you will need 2 mounts and 2 tests, one for X and one for Y axis tuning.Highly recommended for the amazing print quality improvement!

Works good with Klipper. I am new to 3d printing with Klipper but seems to help with smoother prints.

I run a ender 3 v3 ender extender 300xl with sprite pro, bl touch, etc mods. Running klipper in docker, had to figure out how to get software requirements installed. once done, tuned x and y axis. Maker does not have any sprite pro mounts provided, and none of the provided worked, so not exactly "universal", but I made due remixing an existing model. Worked great.

I had read about Resonance Compensation and Input Shaping when I first setup Klipper, but when I saw the scary "mounting the accelerometer" photo in the docs I threw the idea into a "yeah, right, that would be nice category" and went on with other things.That was until I was browsing printables one day with my printer model in the search (an Elegoo Neptune 3 Pro) and came across some "kusba" mount files. Which lead to searching to figure out what the thing was, which led to the amazon order. Just a few days for the package to arrive (I printed a mount in the meantime) and less than 30 minutes after that I had my resonances measured, graphs generated and all new acceleration settings in my printer.cfg.The firmware was already installed on the KUSBA, the directions were clear and easy to follow and my print quality and speed shot up immediately (run a pressure advance after you have done your resonance).I am currently upgrading my hotend so I will be retuning after that, and I am thrilled that the process is as simple as it is. Highly recommended for any klipper users and tinkerers.

Works amazing, easy to use just follow the instructions from the QR. Got input shaping done on ender 3 with klipper in under 5 mins.

I bought this for my Elegoo Neptune 4 Pro after doing some research. Following the calibration steps seemed easy, I found a bed mount and an extruder mount so that I could test X and Y separately since this is a bedslinger.The instructions weren't quite foolproof because I kept getting an error when probing the accelerometer (got ff vs e5). I had followed the instructions to get this configured, but didn't realize that my printer config file already had settings that were overwriting what I was configuring. Check your printer.cfg for an adxl345 section and a resonance_tester section if you receive this error.While attempting to fix the error myself, I was able to successfully, and easily, flash Klipper onto the device without issue, and was also able to easily flash it back to Rampon, which it originally came with. The device is very compact and very easy to use, but you will have to know a few things about your printer, like how to SSH into it so you can install some apt and pip packages. This isn't difficult, but you'll need to know how to do that for your specific printer to get anywhere with this.I reached out to xbst on the official KUSBA github page (you can also drop into their Discord) and they were helpful in quickly getting me to correct my mistake so I could get to calibrating. Solid engineering and great customer service.
