Your second test seems quieter, or that a deception? Did you make changes to reduce the noise?
In the initial tests I ran the servos at 100% velocity
In subsequent tests I’ve been running them at 30% velocity
It makes a small difference in terms of the noise
To be honest, I feel that I just need to apply more silicone grease on the pistons to make things smoother
