I have a problem i recently discovered. My home has AC current leaking from all electronics i use. my laptop power supply, my 3d printer, etc..
This was not a major issue until i built my 3d printer. the inductive bed sensor uses 12v directly from the power supply. the leaked current is messing with the sensor readings on the RAMPS board.
Anyway, is there a way I can get rid of AC current leaking into my power supply output ? (12v)
I tested the leakage with a mains voltage live wire tester. all lines (+ve and -ve) were hot. I switch the power supply to UPS only power, and the leakage is gone, so its not a power supply issue i guess. besides, its happening to everything in the house.
I need to mention that i live in a country where there is no earth.
