3D Printer enthusiasts know most printers have quite a bit of noise when running. This is due to the stepper motor driver which is an A4988. A solid driver but quite noisy.
Creality has released a new main board version 1.1.4 which now includes the TMC2208 silent stepper drivers.
You can see one installed and in action on Teaching Tech
If like me you have already heard enough and want to order one they are available directly from Creality's website.
