    For those who have used the LH motors, what is the greatest source of the noise? Cooling air intake, cooling air exhaust, vacuum exhaust?

    Has anyone ever used another means to assist in cooling, like an external fan?
    Hi 80grit, the fans are loud but not from one area or the other, if noise is an issue I would locate the fan box in another area ( that's what I will do next )
    I know others have added cooling fans to the box, Lighthouse says the fans can run fine @ 180 degrees.
    One thing for sure, DO install a filter! I have read others say they clean the system real good and the spoil board will be the filter BUT
    I know for a fact, stuff happens and when I cut through my spoil board ( all the way and then some trough ) I was very happy I had installed the filter!
    I know the vacuum hold is awesome!

    Thanks, Tim.

    I do have enough space to put my vac system outside. It would just be more expensive and time consuming. I'd have to build some sort of covered structure onto my shop to make it work. I've been looking for an excuse to get my loud air compressor outside, though. This might be the excuse I need to make it happen.

    I asked about what part makes the most noise because I figured one option would be to just run the exhaust out the side of my shop if that would gain me much, but like you say, I the whole unit is noisy. I will find out first hand in a couple days when I get my motors.

    Will, I have a 6 zone cut file for a 4' x 8' but its on the other computer, I will try to post it tomorrow - Plastic board? for your plenum? if so 3/4" thick would be best.

    Thanks Tim. That would be great. Yes I was asking which plastic for plenum? Someone told me starboard but I'm sure there may be others. Are you still just using MDF?

    Yes I am using MDF, would like to use Starboard but it is high dollar at this time. Do you have Vcarvepro 8 ? that is what I used for the cut path.
