RFI EMI Noise Suppressor for cables

gallaghersart

My goal is to have many high speed FDM printers in same room, and as close to each other as I can.

I’m using 18AWG Shielded Stranded wires.

Would it benefit from adding magnetic RFI EMI Noise Suppressor to each wire? And if so should I place one at motor or drive end of cable? Or both?

Thanks!

Are you worried about EMI between machines in the same room? I'd be more worried about wires within the same machine (endstops/steppers/sensors).

Braiding and twisting the wires is usually enough and using good grounding techniques for steppers and frame.

Do you mean ferrite cores/chokes likes these?

@phaedrux Thanks, those are like what I'm talking about, just not name brand.
