Hello,
I took a closer look at a printed engine holder and noticed that a lot of movement from the engine (turbulent running) is transferred to my complete system.

As far as I could pursue the problem of motor racing, I use between motor and holder a clutch of moosgumi (foamed rubber) and between the shaft and motor also mossgumi, despite this, a lot of motor unrest is carried over.

in an attempt, I solved the screws strong so that they only keep the "postion" -> The wave ran curiosity, however, I do not know where the enstchandten forces in the operation are led.

Is that too problematic or in the context of the movement oki?
