MellowFly: A Better ADXL for Input Shaping

I’ve tried a few different AliExpress ADXL’s for tuning my printers over the years. Each one had me solder (which I am not great at), find and read poorly translated how-tos, or deal with making an umbilical. So, after the ADXL on my Voron 0.2 stopped being reliable, I went on a hunt and came across the MellowFly. For $15 USD delivered, I felt it was worth the cost.

A Few Reasons I Like It:

  • Has the Pi 2040 chip, which is easy to flash and well documented.
  • Has a USB-C port. Everything in my life is moving to USB-C; it’s easy to find a cable and use it.
  • The setup documentation is well written and easy to follow.

If you want to buy it, this is where I got it from:

I also have an STL for how I mount it to my Voron Zero’s Mini Stealthburner. It’s just press fit, so super easy to install and remove whenever you need to run Input Shaping. Cop that STL here:

Give me a thumbs up if this works out for you on Printables!
