CNC 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

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!

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.

Works great!

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

It fit my 500 watt cnc spindle perfectly.

Install the dust boot today, I am verry pleased with it, Install was easy, had to shorten the brushes,Only thing that would be nice is if the provided access to different lengths of the brushes, Overall verry pleased with it, I made three test cuts and little to no shavings or dust.Up date. Looked and they make a replacement for the lower part with brushes , I ordered it and its perfect, a bout a half inch shorter, Works perfect, Thanks. Now I am really a happy camper.

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

I ordered this for my Genmitsu 3018-PRO with the upgraded 775M spindle. I noticed when I installed it that it blocks the lower ventilation holes on the motor but figured it was done that way for a reason. I ran a 30 minute cut. I have a 1/8 inch bit in there and had all kinds of issues with the bristles being too long and getting caught up in the cutter. I also noticed after the 30 minute cut the spindle makes some new really high pitch noises and it feels less smooth to rotate than before. I trimmed the bristles about 1/4 inch and ran another hour cut. The spindle did not seem to get any worse but I ordered a new one anyway. It sounds that bad. I'm going to drill some holes in the mounting plate that match up to the vent holes in the spindle motor. Looking at every other design I can find for a 775 size motor they all have vents in them for the motor to breathe. I emailed Sainsmart to tell them this is probably a problem but figured I would warn potential buyers anyway. Drill vent holes in the top piece. Other than those 2 issues it works fairly well. Keeps some of the dust off every flat surface within 20 feet of the machine. The bristles do clog up so keep that in mind for longer cycles. The magnetic attachment is great. Makes getting it off nice and easy but it is strong enough to not randomly fall off.
