A while back I bought a new dust shoe for the CNC machine. I used it very little, and put it under the cart to try at a later time.
Well tonight was that trial. I switched out the boot on the machine with this new one, a design that directs the vacuum more towards the bit. I flattened a live edge slab, with 2 epoxy rivers. I have never had less clean up from the CNC before. Flattening slabs with my 2 inch bit and the existing dust shoe has always thrown debris everywhere, and caused a lengthy clean up time. Tonight I could barely tell I was using the machine. It took less than 2 mins to clean the machine afterwards, and the dust collection bin had all of my debris in it.
It does have a metal frame and uses a hex screw to clamp around the spindle. The frame splits in 2 with some spring clamps to allow easy bit change. Even my 2 in bit got nowhere near the frame, and the bristles help up great to the drag against my material.
I left it on the machine, and left the existing one on the side of the cabinet. I’m not sure if others will agree, but I think its an improvement.
@zackg I did zip tie the new air assist up higher on the z axis, so I could try this out. I’d be really curious if it cleared out aluminum chips better, but if memory serves me, you don;t use the dust collection while cutting. It didn’t seem like the air solenoid was permanently mounted, i hope you don’t mind me moving it.
