Radio noise

Post by cvhorie » Wed Dec 30, 2020 11:17 am

I am running an eShapeoko kit to create large photographic scans. While doing this, I listen to the radio. But there is quite a lot of interference and noise on the radio while the Arduino is switched on.
The electronic kit is three NEMA 17 stepper motors, three drivers, a laptop power supply, an Arduino Uno and a GAUPS shield all joined using CAT5 cable,
so no Z movement or spindle. To drive the camera, there are two USB power supplies for the camera and a cheap PSB pair of relays to control the shutter, and a couple of Ikea LED lamps.
I have included no shielding or suppressors.

Can you suggest a process to reduce the noise?
Thank you.
