Hi, I think that your request is more related to the Marlin core, maybe you can ask in the Marlin forums if that is possible to be implemented.

you can try using an EMI filter like this one here

Thanks for the suggestions. I thought this repo was a Marlin modification to enable some of its features. It appears i have to make a custom build to enable this feature. However, I haven't figured out which exact one just yet.

Thank you. My power supply has one built in already. However, the EMI is on the printer itself, not the grid ^^
The "EMI" i am mainly talking about are voltage dips because the low frequency switching. Not something easily solved by adding a capacitor or filter.
