Dust Shoe for 42mm Spindle

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!

This is the dust shoe to have for the 3018. I suggest you buy the shorter brush as well. I used a hot nail to pierce openings matching the motor cooling vents as others have mentioned shorter motor life from overheating. A small shop vac provides all the vacuum needed to keep cutting dust to a bare minimum.

I love this dust buster. The only thing i hated is the head is so hard to get off when you need to setup for the next cut. I did a small mod splitting the front to give the bit space to pass.

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

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.

It works well

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.

I have not try it and it is already broken. It is to weak for what it was created for Update: Today I received an unexpected email from SainSmart were they are telling me that they were sorry about what happened and that all their products come with a one year warranty and that in my case they wanted to make a brand-new replacement…… what? I never ask for it!! They send it to me and as I told them, this service tells me that this is a company that cares about customers and I really appreciate that …. Once I receive the replacement we can talk about technical performance since related customer service you already have a100% satisfaction

07.04.2024 Habe die Absaugung für meine Vevor 3018 CNC Pro max gekauft und bin voll zufrieden. Das montieren mit den mitgelieferten Schrauben geht schnell von der Hand und per Magnet werden das Zwischenstand und der Bürstenaufsatz "angeheftet". Im Video sieht man wie gut das Ganze funktioniert. Für einen kurzen Gravierstichel waren mir die Borsten zu lang, sodass ich sie abgeschnitten hab. Später habe ich dann festgestellt das es hier einen Aufsatz mit kürzeren Borsten gibt. Dadurch dass man die Einzelteile einfach abnehmen kann, reichen ca. 20mm Luft unter dem Fräser um sie wieder zu montieren. So kann man für den genauen Blich beim Einrichten die beiden Teile demontieren, dass man einen fällig freien Blick hat, wenn es dann los geht, eben 20mm hoch fahren, anstecken und ab die Post. Natürlich ist solch eine Vorrichtung auch schnell selbst gedruckt, dann ist sie aber nicht so schön transparent und evtl. auftretende Verstopfungen (noch nicht passiert) erkennt man erst wenn es viel zu spät ist. PS.: da mein Werkstattsauger defekt ist habe ich aktuell nur einen Haushaltssauger mit Zyklonabscheider angeschlossen. Bei noch mehr Saugleistung wird das Ding aber nicht schlechter funktionieren.

This tool is again, very helpfull and well construted. It works like expected.

Fiz várias compras de produtos da Sainsmart e, no final, a Amazon devolveu-me todo o dinheiro – o que já diz muito sobre a experiência... 🔹 Qualidade? Ok, mas... Os produtos até parecem bem construídos, mas a verdade é que os acessórios são mais caros do que a própria CNC. Quando percebes que estás a gastar mais em upgrades do que no equipamento principal, começas a questionar se vale a pena. 🔹 Manual? Instruções? O que é isso? A documentação é pouco clara ou inexistente, o que torna a configuração uma dor de cabeça, especialmente para quem não quer perder horas a tentar adivinhar como usar um acessório. 🔹 Preço vs. Benefício – Um desastre Se estás a pensar melhorar a tua CNC Sainsmart, faz bem as contas antes... porque com o preço dos upgrades, mais vale comprar uma máquina melhor desde o início. 🔹 Conclusão Felizmente, a Amazon resolveu a situação e reembolsou-me tudo, mas fica o aviso: compra com cautela, porque os acessórios da Sainsmart podem acabar a apanhar pó na gaveta. ⚙️ Nota final: 3/10 – Se precisas de um acessório, procura uma alternativa melhor (e mais barata).

The Genmitsu CNC Dust Shoe is a fantastic accessory for my 3018-Series CNC machine. It was easy to install, and the magnetic design makes bit changes a breeze. The transparent ABS material allows me to monitor the process while the nylon brush effectively keeps dust at bay. It’s well-built, and for the price, it’s an excellent investment to keep my work area clean. Highly recommend! 5/5 stars!

When this first arrived it was unfit for purpose But after chatting with the supplier they offered to send out a replacement head The new part works perfectly and now my CNC router is kept clean and dust free Thank for the replacement part and for great customer service
