Adv Filtration - bed leveling and nozzle cleaning issues

Hi everybody,

Since I installed the adv filtration kit for Prusa Core One I have been having issues with all my prints during bed leveling or nozzle cleaning part.

The moment I turn the Chamber filtration to "none" from the settings menu bed leveling or nozzle cleaning passes straight away.

I troubleshooted whether this is an elctrical or mechanical issue by detaching the fan box from the printer, holding it in my hand and sending a print. No issues when I hold the fan box in my hand so it is not electrical.

Actually when you have adv filtration to on which by default is 40% fan if you touch the coreone frame or place your head chin on a frame you will notice a subtle vibration. I believe this is interfiering with the load cell while doing bed or nozzle cleaning.

Anybody else having this issue ? I see noone complaining about it... Am I having a bad fan ? 
I already took it apart and back again to make sure all is correct.
I can replicate this anytime....

What I do as a workaround is having adv filtration to "none" and then once the print passes bed leveling and nozzle cleaning section I select tune and turn it on again.

If this is a generic issue maybe this can be done in firmware and disable it during leveling and cleaning, no ?
