Interesting topic. In theory I would agree that 0.9° steppers have advances to 1.8° steppers.

Battle of the 48mm!") ](https://www.youtube.com/watch?v=nWoUAQyIQb0) To bad he is not telling which advanced driver settings he used. I guess settings tuning might help to make the 0.9° steppers quieter.

If you double your Z axis stepper microsteps the quantization you are seeing will reduce in half, etc. EDIT: For example, my modified CR-10S Pro uses 4 mm lead screws with 0.9 degree steppers, which gives me a 0.01 mm resolution per full step. I therefore would get 0.000625 mm resolution per microstep with microsteps set to 16. In practice, I use 64 micr… maybe he makes a statement here. He even uses 64 microsteps!
