I had a whole box of those dampers, I’m not sure if I threw them away or not, like 100 or so, I pulled them off the first few batches of mpcnc steppers I got.
There are a few things, the house was absolutely silent when I shot that. It is on the mini-rambo, so 16th stepping is a bit louder (I can test it on a ramps to see if that is a major difference). Long belts and thin wood, Maybe I created an instrument not a zen table? It really was zipping around at a lower speed maybe it won;t be so loud. Maybe the axis not being clamped in place makes it louder.
So many unknowns. I will just keep going and see what happens either way I am learning a ton about corexy.
