I'd like to hear comments on linears and dust. I like the idea of a moving table due to having the strong gantry but I'm worried about dust on the ways if I use roller blade type setup. I know if I had the money I could use something like a Drylin bearing that wipes as it goes but I don't have this kind of money.
The X axis is probably the most critical followed by Y and then Z due to position. Correct? I think a roller blade setup for the Y isn't too bad since the bearings are at angles. I suppose you could put the bearings for the X in positions other than top center relative to the pipe to avoid the dust since it will flow off the pipe everywhere else other than top center.
I'd like to hear comments about your experiences and solutions. I can make seals for a moving table that will wipe the way but is this needed?
If there is already a discussion about this please forgive and point me to it. I failed to find it via search.
