I just attached them to the standard motors from the FT5 kit.
There is really no need to change the motors that I can see, though I did try a 0.9 degree motor on the extruder before changing over to a geared Titan version (with the original 1.8 degree motor).
The 0.9 degree motor did not have remotely enough torque to directly drive the original extruder.
To be clear, the dampers I am talking about are two metal plates with a rubber cushion in between.
They attach to the motor faces and then to whatever the motors originally attached to.
I have them on all the motors except for the extruder.
Some people have referred to inline diode boards as dampers.
If that is what you were referring to, I have not installed them on my printer and have no plans to do so.
If I wanted to try something like that I would just build them as I have a bunch of 3 ampere Shottky rectifiers in a box lost somewhere in my workroom.
But again, the rubber dampers work so well that I see no need.
