No-hassle Support & Resource Center
You can find detailed instructions in the SainSmart Resource Center (see User G u i d e). Besides, we have a CNC community, you can get help from others in it. What’s more, our customer support team is always ready to assist with any questions you may have.
Structure Stability: Stability is enhanced with a new steel HSS frame. Each axis features two 16 mm Steel HSS linear tubes, lead screw motion drivers, dual Y-axis rails, and an all-metal frame.
Upgraded Control Box and Mainboard: The upgraded control box features essential functions like emergency stop and home buttons. Its metal casing is dust-proof and easy to maintain. It includes a powerful and quiet Toshiba TB6S109 driver with a 32-bit chip, along with multifunctional ports for air assist pump and MPG.
Compatibility Upgrade: The 4040-PRO CNC machine is supplied with 42mm and 52mm spindle mounts, compatible with original spindles and 300W spindles. Additional 65mm (B0BRZSY475) and 69mm (B0BRZSVVK3) spindle mounts are also available for separate purchase.
Various Upgrade Accessories: Supports a 4th axis rotary module kit (B0C581H2B3), allowing the 4040-PRO CNC to carve from various angles or perform full 3D rotary carving with the right software. Enables a Wi-Fi module (B0DK54JHS6) for mobile control. Also you can upgrade the XZ-axis(B0DHGN4ZYH), strengthen the screw material, and improve stability and speed.
Easy Assembly: Main parts are pre-assembled, enabling setup in about 15 minutes. The spoilboard consists of two replaceable MDF boards, so you only need to swap the damaged one instead of the entire spoilboard.

A great machine at a great price
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.

Buy this not a Fox Alien rubber Band CNC
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.

Great hobby machine
Bought this to dip my toe into CNC. I’ve used it mostly to carve catcall trays, trivets, and cutting board stands using small bowl bits and end mills. Nice to turn this loose on a job while I do another things in my hobby shop.Assembly took me about 30 minutes. Tools to assemble where included, as well as some 30 degree vBits and some spare parts like extra homing switches. Documentation was easy to follow and all parts in the included container were labeled. The machine feels sturdy. The included spindle has ER11 collet, and I think the included collet insert was 4 mm? I purchased a 1/4 collet insert so that I could use bits that were more available to me. I’ve since upgraded the spindle to a Makita 701C router, which it handles just fine, just have to be aware that this isn’t going to cut at 200+ inches per minute- i think max speed is like 78 inches per minute and I hesitate to push it that hard.For what I’ve used it for, it’s been great. It’s now a fixure in my shop, I’ve built an enclosure for it, added the dust boot, and plan to add the hybrid spoil board in the future.4 stars because I don’t see many spare parts for it on Sainsmart’s website. Things like backlash nuts will eventually wear out and I’d prefer to go to the manufacture to get the replacements instead of hacking something else in there. I’ve had it for 3 months now and that is my only complaint.

Great inexpensive cnc for hobbyists
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.

Junk!
I have had a BobsE4 for about seven years now and this machine moves four times slower than it does for no reason at all. Customer support says the machine is fine so if you like a project taking 11 hours instead of 1 1/2 then this is your machine! I am very disappointed in this, it looks great and is made very well but it’s very slow and then Candle software is very problematic. This machine is like buying the nice shiny sports car and finding out it has Yugo engine in it!

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
Nico Jansen in de wal –
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!
