motor whine after movement

npm1

Hia,
when I move my corexy axis the motors whine really badly, when no movement occurs i hardly realize it is on

By setting X and Y to 1/64th stepping, it prevents those drivers from using interpolation.
There's not really any practical benefit to running 1/64th stepping anyway, as you are highly unlikely to actually get that mechanical resolution. Most people run 1/16th, and the interpolation just smooths the motion.

But your question:
The motors are whining because they are resonating (different motor windings will do that at different frequencies). The drivers try and avoid this with a clever thing called 'SpreadCycle', which is on by default. You can try playing with that setting by adding the command M569 Pnn Dnn
For example: M569 P0 D2 sets the X driver to SpreadCycle. M569 P1 D1 will set the Y drive to random off time.

Remember you can just put the commands into the console to see their impact before you edit config.g

If you are really desperate for silence, try 'StealthChop' but be aware that it drops the torque by a huge amount.
If you want to know more about StealthChop and SpreadCycle, check out Trinamic's documentation.
