I see people talking about dust getting inside the controller box and even in the power switch. what if you put the controller inside a box built with furnace filter type filters? appropriately sized of course? then you would simply change the filter out when you needed to. could save a lot of trouble.
Hey Robert,
this is a good idea which is only limited to how you affect the ventilation for heat dissipation of the controller. A temperature sensor inside the box would make sense then. Another way would be to enclose the source of the dust, e.g. by an enclosure like this or this (view of dust hose outlet here and here).
I have experimented for a while with filters for fans on PCs, but it turned out that they immediately limit the air flow and also clog too quickly (I have seen someone using such a clip-on fan filter on the (in my opinion too small) fan of the Onefinity Controller but I don’t think this is the right solution, especially not with such a small fan). My solutions since then have been to run the computers in large enclosures with a filter at the entrance of an air circulation system. This allows for a larger filter area and therefore better airflow and less clogging.
I think your idea is good.
PS: Note that with Version 5 of the Onefinity Controller, the power switch is now a push-button (with additional circuitry onboard) which replaced the rocker switch of the Version 4.

I used furnace filters in an enclosure around my 1 1/2 hp dust collection system and they definitely help contain the mdf dust. I mounted a coarse filter ahead of the allergen one. Plan on doing the same thing to the controller. Window sheet film makes an inexpensive enclosure and it’s also see through
yeah i was thinking more like a box that had filters on all sides not just in front of the fan. you are correct…
You will want something that will circulate the air through the filters to ensure you’re not making a micro-climate inside the filter box circulating hot air around and through the controller.
FWIW if you’re experiencing significant dust build up in the controller you should also consider the health effects that dust has on you, it might be time to invest in better dust collection. I’ve had the Onefinity controller in an active shop (4+ hours per day with tools in operation 7 days a week) with the controller running and there’s about a 0.5" x 0.5" patch of dust on the enclosure next to the fan.

thank you wayward. I do not yet have my OF but i am getting ready for it now, learning software and building my table. I am also reading just about every post i can find on the problems folks have with whatever comes long
Hey Rober,
you need an air flow that goes through your box, which means you need an entrance for the air (where the filter would sit) and an exit for the hot air. Otherwise you would have no cooling.
Yeah it’s an exciting time for sure, once you have it you will figure out what’s necessary and what can wait… Keep in mind there are now thousands of Onefinity machines out there in the market so when you see an issue that happens only a couple times then it’s likely not going to happen to you (statistically speaking 
)
