Why do different drivers change the noise of steppers?
Stepper motors contain two distinct sets of coils. The current in these coils is governed by your stepper motor driver.
To move the motor in either direction, the coils are being driven one after ...

How do you make sure you have the right voltage on the trimpots on an A4988 stepper driver?
Generally speaking voltage on stepstick output should be around 1V.
To imagine more or less what the current and what the voltage is, you can think about it in the same way as about water.
The wire ...

Can I mix TMC drivers with A4988 on the same RAMPS board?
Yes you can mix different drivers, including the TMC drivers (e.g. using for X and Y only).
How you do that is described in this instructable.
Please do note that, from observations, the 8-bit based ...

How should I power these stepper motors

Why do different drivers change the noise of steppers?
The coils in the stepper act like speakers. Its not that the stepper is making less noise, it's just making it in frequencies that are above the average person's hearing.
