After a day succesfull printing..Troubles about stepper motor driver to hot and toolhead behavor.
Ik can't find any solution. After a new main board, now again troubles with stepper motor drivers.
And very annoying noise and jerky movements of the toolhead.
Checked everything, no loose parts, belts tensioned, no chafing parts, could not find anything causing this.

Do you have a fan pointed at your stepper drivers?
Yes, but I have disconnecting the fan for a few minutes to connecting the carbon filter wires to the board. Strange situation..
