Genmitsu 3020-PRO MAX V2 CNC Router Machine, Upgraded 3 Axis Engraver for Metal, Wood, Acrylic, PCB MDF, New Structure & Offline Controller & 6pcs Limit Switches, Working Area 11.8 x 8.1 x 3.1 inch

Edit: Customer service is excellent. Special thanks to Hong from Sainsmart. My PSU failed in the first week of printing but Sainsmart sent me a new one and I’ve been carving up aluminum ever since. It’s handy, sturdy and it works exactly how I would expect it to. Coming from a 3D printing background, I expected to have more tedious issues to iron out but it is a fantastic little machine. Recommendations: 3D modeling and CAM (the tool passes): Fusion 360 G code sender: UGS works really well for me Endmill for cutting aluminum: 1/8 in 3 flute carbide endmill. (Speed tiger here on Amazon hasn’t failed me once. Literally. No snapped endmills ever) Old review: I think it’s a solid little machine and I love it very much. But on my most recent CNC job, as the spindle began to spin at the very start, I hear a pop from my PSU and some smoke came out. I’ve reached out to Sainsmart for support both here and on their website. I hope to get a replacement part and fix the machine because it is lovely to use when it works. I will update this reply when customer service reaches back with me.

This is my first CNC router and I chose this over other models because it appeared to be more rigid than the average low cost CNC. I was quite impressed with the overall build quality, fit, and finish. The packaging was very good as well. I checked each and every bolt and all were properly tightened at the factory. Assembly was quick and easy - much easier than my 3D printer. It needed calibration on the steps/mm but that was expected. I have a lot to learn but had my first carve project up and running in no time. I have not tried cutting aluminum yet but my guess is that it will do fine as long as I use the right bit and take it slow. Update - I can attest that if you get your feeds and speeds right you can mill aluminum quite nicely with this machine. I tested it using 60 degree v bit which worked fine and then I made a little test design in Fusion 360 to cut a curved slot, some counterbored holes, and the edges of the part using a 1/8" single fluted flat end mill. The image shows the result in 10mm thick aluminum. This took about an hour 15 minutes to finish in the mill.

at first the machine was running as expected, but soon started being loud, vibrations and loose screws. I than noticed the Z Axis bearing was loose and Sain Smart sent a replacement Z Axis, the new Z Axis set screws were poorly installed and after about 15 minutes the new replacement Z Axis the bearings completely fell out of place and set screws were loose and I broke a cutter, the service people take so long to respond it is as if they don't care, or are over head with complaints, my newest issue is the switch for shutting off power stopped working I have to pull the plug every time I shut down, today 9-12-23 I wish to add customer service is and has been reaching out to help replace poorly assembled and badly damaged parts customer service is good and helpful changing rating to four stars

UPDATE: 8/26/22 - I have been watching someone uploading new videos of the router table, their spindle is running smooth & this is my major concern. I am tempted to order again but fear if I get the whole machine put together again then find my spindle, which seemed okay the first time UNTIL I turned it on, will be imbalanced again. It is a hard decision. I think I only got a lemon. It had the bad socket for the Z stepper anyway. Maybe I should order again. I am weighing this option heavily. I want to have this or the proverxl very much. I already have a large CNC machine from Stepcraft (much more expensive line), I want something small. I want to tinker, I want to upgrade, I just want the base machine to also be nice from the start. —-original review below—- I open the package which arrived with small holes in the box. Everything seems fine. First sight of trouble: Little screwdriver handle is cracked. Snapped right off, it was hanging by a thread. “No big deal, just a little screwdriver, I have iFixIt & I will use my own drivers”. Hex keys are okay, they give more than you need for some reason. I go on, assemble frame - wow, solid, very nice. Now comes to wiring. Watch videos, see mess. Try myself. Mess. All thought to frame, NO thought to cable management. For this price, where are cable drag chains or silicone wiring? Plug in steppers last because it is good practice. Discover Z axis Stepper Motor has a little chip out of the plug in socket. “i hear they have good support, I will ask for a replacement I guess - community on FB is good”. Plug it in, seems reasonable - turn on machine. Jog a few times x & y, cool. Jog Z. Vibration. Turn on spindle: Extreme imbalance, vibration. Maybe it is okay, maybe it is not. For 50 dollars MORE than it used to be, for 500+ dollar small CNC, the unit I received is too much of a gamble. I am saddened & depressed about it. I loved everything about it except the wiring + the broken stepper plug (another reviewer had this issue, theirs was worse, mine was still enough to worry). I give Tech Support 4 stars because community seems to love them & their community is active on FB. Accuracy low because this kind of imbalance could not ever be accurate. YMMV. For beginners I will give 3 stars. Maybe? It is not difficult to assemble. It is sturdy. The QC issues I have faced ultimately lead to me now returning the machine. The gamble is too high :(

Junk. Not leveled. No way to factory level. Depth is inaccurate. Stops midway thru projects even with ultra conservative depths. 300 Chinese watts must be different. Least accurate machine I've owned.

I’ve never used a CNC Machine before purchasing the Genmitsu 3020-PRO MAX, and to be honest I didn’t know if I could figure it out. I have to say that I sure had a lot to learn. Granted I did watch a whole lot of YouTube and seen the different types of machines. The one thing that hooked me was the wood cravings that could be created that as a wood craftsman I could never accomplish with the limited experience I have. I chose this machine over others was first the price, ease of assembly (it comes mostly assembled already) and simplicity of the operation. I purchased my unit in July of 2022 but since I was not ready to start I didn’t open the box till June. Getting the 3020 was pretty easy. Learning the difference softwares and programs was the default part. The box it came in had all the parts and manuals to put it together but was missing a USB stick with the software! At first I was a bit taken back by this and sent an email to the customer service department. This is when I first realized I had made the right choice. A service member (Hong or Mr. Hong) was right on spot with sending me a link to download software. I used a Laptop with Windows 10 and was able to setup the comport and install Candle. A software that uses files called gcode (*.nc file) to tell the machine what to do. Also one of the files was a test file that craved a small 2.5D image. I know this now but didn’t know then that a machine with three axles will only crave 2.5D as the other 0.5 is the flat surface on the bottom. From this one file I was able to figure out the files needed to take a object (2.5D) and turn it into a work of art. To my surprise it actually takes three steps to complete first. 1st was finding the object files. Too my delight in found 1000’s of free files in a *.stl format online. As I’m not going to use these files or creations to sell I downloaded and modified using a software already available in Windows called 3D Build. I then downloaded a trial version of MeshCam. As my CNC machine is located in a spare room, I used another Laptop to modify the files, open these files with MeshCam to create the tool paths and convert the files from an STL file into a NC file that the Genmitsu 3020-PRO MAX uses. I only was able to convert 15 files using MeshCam before the trial version ran out. I have tried other softwares but after using MeshCam I will pay for the license ($250.00 one time payment) as other programs where not as easy to learn and the results as positive. I would have purchased the software already but ran into issues with the stepper motors. I started getting what I first thought was banding with the X and Y axis that increased very quickly, projects halfway completed were being ruined. I emailed Hong and told him my troubles and he sent 2 new stepper motors to me free of charge. I installed the new motors and it’s back to creating beautiful works of art. While the machine was down I was able to give the machine a good cleaning. My only drawback with the machine is that the manufacturer does not at this time offer a explanation kit for this model. I’m hoping one will come out in the near future. Overall I give this one an 4 1/2 Stars. It’s built strong, service is excellent and it’s a very good investment for anyone looking to get into using a CNC Machine.

This has been a great hobby machine for me. The precision is on part for what I expect from this level of machine. My projects are small and I know I'm not using this machine to it's full potential. So far, this machine has yet to let me down. I mainly cut printed circuit boards and some very light aluminum projects. For aluminum, be patient and use good tooling. Cheap bits will let you down. I would say that the learning curve is steep but with AI and plenty of maker boards, you should be able to find out everything you need.

I like how well built this machine is, but I have had to return 2 of them already. In both cases I was cutting 1 mm copper on very conservative settings 1 mm/s for plunge and feed rates at 12K. The machine stops. The y-limit switches are both on when it stops but the bed is nowhere near the limit switches. And it is dead. It won't move in y. Nothing seems to fix it. So there must be a design fault. I looked at other reviews and customers that have issues, have issues when cutting metal. But at the settings I was using is was doing well but it would just die. Always in the same way. It does cut well for acrylic which is the other thing I use it for. As always with Chinese manufacturers getting ahold of them can be frustrating, good luck finding that link on Amazon. Prior to this machine I returned 2 Lunyees they are worse than this. One was dead on arrival with a limit switch not working and the other started drifting off the toolpath. I don't know, they are probably fine for wood and acrylic. There has to be a design flaw because both failed in the same way, with different end mills.

This mini Cnc 3020 pro max arrived well packaged. This machine is well thought out because it is extremely easy to assemble because all the different parts are pre-assembled, the holes drilled and tapped. It is a comfort for any person (beginner, intermediate or confirmed). I followed the installation manual in English without difficulty. Everything is referenced and imaged. It took me nearly 45 minutes (unpacking + assembly) to get the final machine. This Cnc 3020 pro max has all the possible options. Nothing is to be purchased additionally. It has: a rigid aluminum plate of 30x20 cm, limit sensors, reinforced axis guides, a depth sensor, an external screen. There's even the micro SD card adapter included with the screen. The parts of the frame are massive and neat, it is a guarantee of quality. Safety is also an asset with its emergency stop and its box which hides the electronic part. All these options make this machine a reliable and efficient means of production. To improve the life of the top, it is advisable to install a martyr plate of the MDF wood type. Ideally, it allows rapid prototyping at home, in school to learn about engraving or machining easily. I carried out some tests using the Grbl software and the files present on the USB key supplied with the machine. Just connect the machine to the "Com port" with the USB cable. Grbl software icons are very intuitive. All you have to do is make the machine origin in x, y and z, then open the file and start machining. Whether engraving or machining, with tests on plastic or wood, the CNC is up to my expectations. I highly recommend her.

Shipment was quick and building the machine was easy. After a few runs the spindle motor stopped working. After contacting Tech Maker they shipped a new motor from China to the Netherlands in a few dates. Great product and great service!

Really nice machine to start with.

This is a first class CNC milling machine. I am a professional library maker. I've taken on a commission to make a model of 11c abbey. I am used to CAD design and solid modelling. when it came to this model I made the decision to machine these small parts on CNC. I looked at a lots of machines but was taken by this one and kept coming back to it due to the solid construction and the good reviews. I ordered it in the late afternoon and it arrived the next day. With a forwarded code that I needed to give the driver. This I found reassuring on a high valued item. I watched some You Tube clip on construction. however the Genmitsu handbook is excellent well illustrated in colour with detailed cad models and pictures. I had it constructed and working by the evening, great fun. I then needed to get down to the serious work of learning how these machines work. If your new to this then you need to be patient during the learning. There are lots of good You Tube vids on this. I don't usually write reviews on Amazon I just do not have the time. I had a small issue and contacted the seller. As we all no doubt feel some trepidation that your not going to get anywhere. I could not be more wrong. I was emailed right back the next day by Jamie. He resolved the issue and followed up to make sure that everything was working. He gave me complete reassurance. That to me means a great deal in today world. I am cutting 36 windows in ebony with .8mm cutters for the glazing bars and trifoil window frames in cedar of Lebanon representing sandstone. I am delighted, Getting my head around gcode is not easy but once to you have a grasp then you can build from there. My work is a little specialised and complex. but for lettering and stock carving there are many programmes and images you can learn by. I will post some pictures of this work when I have it completed. Most of all I wanted to thank Jamie for his first class service and following through to make sure all was running well. I have not received anything for this review. This is a genuine reflection of my experience with this CNC machine and the seller. Bernard Allen

The overall kit itself was very easy to assemble. Great instructions and lots of spare parts. The quality of all the cut parts was clean too. Overall, as a kit, I'm very happy with it! However, one of the screws on my Y-axis coupler was stripped making it impossible to disassemble for the Y-Axis extension. I ended up using a combination of tools to get it apart, but damaged the coupler. The Sainsmart team sent me a replacement coupler overnight ASAP while I built the rest of the extended gantry. They took responsibility for the damage and didn't make it a hassle for me. Best support from a company that I've seen in a long time.
