As part of my quest to quiet the CR-10S I’m adding dampers to the X- and Y-axis of the machine. The fan upgrade didn’t do much. I still have hope that this change will make a difference.

The dampers attach to stepper and frame, but the connection between the two parts of the damper is isolated with a rubber like material. The isolation should stop stepper vibration from being transferred to the chassis and remove the resultant “singing”.
X-axis stepper installed with damper
X-axis with all four stand-offs
The brass standoffs have a screw on one end that were used to hold the stepper motor to the frame. Only two are needed when using the damper. I still attached the other two for some protection around the X-axis limit switch. The end nearest the stepper goes through the holes in the frame but are not connected to anything. I need to add the appropriate size metric nut.
Y-axis stepper installed with damper
Both X- and Y-axis steppers needed to have the drive gear moved on the shaft. The gear is held in place with two set screws. I tried to center them such that the the drive belts won’t wear on one side or the other.
Was it worth it? This time, yes. Most of the stepper noise comes from the extruder, especially durring retraction. I have one more damper. I may add it to the extruder, later.
