Hi Robert, and thanks for the reply, as you can see in the video, I already have alu tape, and it works just fine while touching the sensor.

Also..... I tried lifting z, holding a blade underneath the sensor and slowly moving it towards the sensor, it detects it when I'm holding it with my hand, but if I hold it with a plier, it doesn't detect it AT ALL, even after it touches the sensor. So it's definitely a static elec. Thing
