GenmitsuCNC Dust Shoe ABS Cover Cleaner for 3018 Series CNC Router/CNC Machines with a 42mm Diameter Motor, Hose Adapter Outer Diameter 38mm (1.5″), Transparent

My first time using a dust boot on my CNC machine. Fit perfectly on my ProverXL 4030 V2 machine.

The media could not be loaded. Keeping exposed ways and lead screws clean is critical for longevity of service. I recently purchased the Lunyee 3018 Pro Max and this shoe fits perfectly. I don't think I'll ever use the long bristle option but the short bristle option is perfect, my end mills sit about .2" below the bristles. I repurposed an old vacuum cleaner which delivers high pressure to the shoe and I have ZERO debris escape from it. I see videos here wherein the bristles are dragging the project piece which is not correct. My 30° V-bits are very short so I fabricated a plate to redirect the airflow so I use no bristles at all. I highly recommend this device, or whatever you can find to fit correctly, to keep debris contained.

Very happy with this well designed item. Fits perfectly and the magnet were a design coup as far as I'm concerned. The base screws to motor with two provided screws and allen wrench then the parts are held together with very strong magnets. Allow for quick , tool less removal to change and zero cutting tools.

I'm addressing a few aspects of this item in this review.1- The concept is great. Permanent attachment to the motor but the body uses magnets to be removed out of the way. I like this part.2- Length of brushes. There are people complaining about brushes getting in the way. The design isn't perfect. Since the boot is attached to the motor it moves up and down in the Z direction. As the motor plunges the bit into the work the brushes also move down. If the Z movement is large, the brushes hit the surface of the work and bend. You have to be careful about that and make sure the brushes aren't too long for the depth of cuts. The vendor says right in the listing, "trim the brushes"You might want to buy multiple brushes and have different trims for different jobs.3- Now this is the main part of this review. This boot design has a MAJOR DESIGN FLAW. By screwing the motor to the part it blocks the air intake ports that are used to cool the motor. THIS IS BAD! Your motor will overheat.You might think that you'll drill a few holes in the boot but that is not a good idea either. The motor is designed to suck air from the bottom, move it up through the motor and exhaust from the top. If you drill holes in the boot, you are connecting the intake holes to the area where your vacuum is attached. In effect, the motor will try to suck air from bottom to the top and your vacuum will try to suck air from top of the motor to the bottom. Not only the air flow will be unpredictable, also you are putting more strain on your motor as its fighting with the vacuum.Easy solution. Create a little spacer like I did in the picture. It lowers the boot about 10 mm but I would not run the motor with the vents blocked.Hope this helps

Works exactly as promised

Great quality and it WORKS GREAT! However, the brush bristles are too long and need to be trimmed shorter. You can purchase a shorter brush (which I did), but I found that to be a little too short (although it worked on deeper cuts). You need to EXPERIMENT to see what works best for you!

Bought this Germitsu dust shoe for my 400W 52mm DC spindle, it works well with an engraving bit but when used with a 1 inch diameter flush cutting bit to level the spoil board the brush's inside diameter is too small and the brush's bristles gets sucked up by the bit and blocks the air flow to the vacuum/dust filter. The dust shoe become completely blocked by the dust and becomes useless.The brush's inside diameter needs to be twice as large to prevent the longer brush's bristles from getting sucked into the bits like flush cutters or Bowl & Tray bits.The shorter brush, also provided with the dust shoe, does not catch all of the dust when used with the larger bits but does well with engraving and small end mills as the bristles are closer to the work-piece.The VAC hose connection of the Dust shoe is not braced very well and flexes a lot with the VAC hose connected I used a "TY-RAP" around the top of the spindle motor and the VAC Hose to keep the VAC port from breaking, it seems to work really well.I like the way the dust shoe is attached to the motor housing and the way it is easily assembled and disassembled using magnets, but the longer brush assembly is disappointing. It only collects dust well when used with bits up to 5mm / 3/16 Inch shank diameters.I'm going to modify the longer brush assembl's ID to 2X the current ID of the original brush.

It's a bit of effort to get a light hose connected so it's not in the way of the machine's normal operation, but it works as advertised. Be sure to get a chip separator to save your shop vac!! They're only a few bucks for a small one.
