I have been looking at keeping the sawdust down from my cutting. I hooked up a vacuum to the tool mount & probably need to revisit making that better, but thought covering the sides would at least cut down most of the dust going outside my table. I saw a photo of someone else’s table that had like a box frame around their MPCNC & that was the start of this idea. I did not have enough room on the top around the CNC to rest a box frame, so I started looking at mounting it to the legs & top ledges.
I plan to use 2 - 2x4x24" studs on each corner with a groove cut down the center for the thickness of the panels. My table saw should be able to cut the groove well. Probably going to use a sheet of 1/4" plywood or paneling cut to 24" widths. I might use a 2x4 fluorescent light cover for one side so I can see it working. The light cover seems to be less expensive than plexiglass. I found a couple of light covers that were $8 to $11 each. They probably will not hold up as well as plexiglass though. I am also going to use 4 -1x2’s at the bottom of the 2x4 corner supports to act as a bottom for the panels to rest against. I will probably ponder this idea a day or so before putting it together to see I decide to change something else. Rigid insulation or Styrofoam panels might work for the sides also & cut down on more of the noise in the process.
I attached a couple of screen captures of the design along with the zip file that has the openscad file I am using. The zip file has the 2 screen captures in it also.
Let me know if anyone has some better suggestions for this idea.
