Genmitsu CNC Router Machine 4040-PRO for Metal Acrylic Cutting Milling, GRBL Control, Lead Screw Driven, 3 Axis Engraving, Working Area 15.7” x 15.7” x 3.1”

Setup was quick and very easy, this is actually the second I purchased because I like the first one so much. It is very user friendly even if you’re a beginner, it produces professional quality results. I purchased upgrades for this machine to include x and y axis extension and routers as well. I had one issue with one of my offline controllers but customer support was excellent and quickly replaced the defective controller. I am impressed with the quality of machine you get for the money, their customer support is also top notch. I did my first carve right after I received and assembled my machine, it performed better than expected, lower noise level than other machines I’ve used, the carve was very precise and detailed and the machine is very solid with no detected play I. Any of axis.

I LOVE THIS MACHINE! This is the best machine for the money on the market period. Here is my story. First I bought the Fox Alien rubber band CNC which was a huge mistake. I was busy with other things so it sat there unused until I got to it. I found out the motherboard was bad, they replaced it and quickly, they even gave me their new 1/4" bit set as a sorry for the issue, which was nice. Then I tried to cut 1/8" cast acrylic plastic and it would not cut it! I added 5 passes to cut 1/8" plastic, and it still would not cut it. Meanwhile I am emailing them asking how to fix this. Their rubber bands would skip and destroy every cut I tried to make. I finally gave up and they would NOT give me my money back on their product. So I bought the Genmitsu 4040 Pro for less money. No rubber bands, just solid metal screw drive. Same exact stepper motors and this thing is a beast. I surfaced my cutting board since the Fox Alien destroyed it. It cut is so smooth it is like a mirror finish. I love this machine. It will cut and it is so accurate, I love this machine. Yes it is not as fast as the Fox Alien, but who cares, it actually works, it cuts and anything. If it fits into the machine it will cut it. Obviously you have to work within limits but this is a beast of a machine. I love it period. Yes I relocated the power to underneath it so I did not break it off, not sure why they have it sticking out the side, but who cares. This thing works so good, get one you will be happy you did.

The unit is great. It was easy to assemble and there are a ton of YouTube videos to help with bringing it online. I intend to carve mostly hardwoods like Maple, Cherry and Walnut. It does a good job using a V bit but the excessive chatter with a 1/4" or 1/8" end mill bit makes a mess of the project when carving pockets or profiles. The unit I have had too much play in the X and Y axis simply due to the play in the spring loaded nuts that are driven by the lead screws. I was able to eliminate that chatter by disassembling the nuts, tapping some existing holes in the floating side to add set screws. This allowed me to carefully tighten the set screw until the backlash was gone but the lead screw could still operate freely. Added some loctite to prevent the set screws from loosening over time. Unfortunately, the spindle motor assembly that was supplied as well as the upgrade spindle with higher rpm also flex too much and the chatter is still unacceptable. The next modification will be to upgrade the spindle motor to a trim router to see if I get the chatter to stop. I'm overall very happy with the unit but I want to improve the performance. For the beginner, Easel Inventables software works great and is easy to use. The first 30 days is free but after that a subscription is required.

This little CNC is great. I can do a lot of work using different CAD systems to create designs. I especially am enjoying a monthly subscription with Carveco that gives me access to a lot of good tutorials for producing lots of different designs, including things like inlays. I’m also using auto cad fusion 360 with good results. The one suggestion I have is that the provided spindle is pretty weak. I replaced it with a water cooled 2 hp spindle from Amazon and it can cut through anything. The carriage and drives seem to be very sturdy and allows me to get good cuts even with the larger spindle. I’ve also found that sainsmart customer service is great and very quick to send parts if needed.

This one had one of the rails bent, so it could not cut anything right. I couldn't even mechanically move it all the way to one side. It would not cut a proper circle much less anything else. I wasted two days trying to use the included software. How a company would let something this this ship is beyond me.

Très bon matériel j'ai acheté plusieurs accessoires en plus et le contact avec le fabricant pour le paramétrage et diverses problématique c'est très bien passé. Je recommande ce fabricant

Bijna 2 jaar geleden gekocht en ontzettend veel plezier van. Een uitstekende machine, makkelijk te monteren en (na enig inleeswerk) makkelijk te bedienen. Ik gebruik de CNC voor het maken van klokken: van de tandwielen tot de frames. Dit deed ik eerst met een electrische figuurzaag maar met deze CNC gaat het veel nauwkeuriger en sneller. Daardoor kan ik meer tijd besteden aan het ontwerp. Vooralsnog grotendeels met hout gewerkt maar recent ook met acrylglas. Machine is nauwkeurig, bijna onderhoudsvrij (af en toe even smeren) en heeft een mooi werkbereik. Sainsmart heeft een goede klantenservice voor zowel technische vragen als aftersales. Mijn Z-probe werkte niet meer en ik kreeg gratis een nieuwe toegestuurd. Uitstekende service!

Gran maquina para empezar en el mundo del grabado y corte CNC. El envío fue rápido, llegó días antes de lo esperado. Muy contento con la compra y con la atención al cliente.

Bardzo dobra maszyna dla początkujących hobbystów chcących spróbować swoich sił w świecie CNC Prosta konstrukcja, szybki montaż i duże możliwości modernizacji frezarki w przyszłości (większe pole robocze, silniejsze wrzeciono, itp)
