If you have a DIY machine, and have the computer that controls it in the same room, are you doing anything special to keep dust out of it? Have it in a special enclosure?
Mine is in a small room with the machine, and eventually I just took the side of the case off as it was easier to clean it out (as it needs it frequently) and it actually seems to accumulate less dust than when it was closed up.
But I figure there has to be a better way...
Thanks,
