Its robust build, array of features, and supportive community make it suitable for beginners and experienced users alike who are willing to engage with the learning curve. For those seeking an out-of-the-box solution for intricate projects without the need for in-depth learning, it may be wise to consider other options.
Cutting to the chase, this machine is great. It's built like a tank, assembly instructions were fine, and there are a ton of resourced available online. I got my machine on Sunday, and on the following Saturday was able to cut the piece in my attached picture with no issues. In fact, the only issues that any of my cuts have had were of my own making. The machine works very well. That said, prepare to do some learning, some troubleshooting, and some problem solving. This is my first CNC, but I have extensive experience with 3D printers, and they're the same way. This machine isn't there to hold your hand while carving out intricate masterpieces. It's a tool that you need to learn to use. Another reviewer said something like "8 hours of failure was too much." (I had the same problem that he did. It was solved by changing the "Safe Retracts" setting in Fusion360.) If 8 hours of failure is too much for you, then this isn't the machine you want. To make this (or really any CNC machine) "work", you will need some basic understanding of G Code, 3D modelling, woodworking, and electronics. You don't need to be a master at any of this stuff, but you're going to touch all of it. It will take time. You will screw things up. You will get sawdust in your hair. That's what makes these things fun. Now, more specific to this machine itself, I was very, very impressed. There are many very similar units on Amazon, and I selected this one because of the included upgrades, and the known brand name. I found the machine to be extremely well built, and straightforward to assemble. The inclusion of limit switches is important. While limit switches can be a bit frustrating, they are there to make sure you don't accidentally send the machine a command that will damage it, and the work perfectly for that. I find the offline controller to be wonderful. There seems to be a lot of hate for this part, but I like that I can run he machine "headless" and not have to leave a laptop in my dust shop. I actually had a much smoother experience using the offline controller than I did using the PC-based Candle, but they both do the same job. My motor doesn't wobble, isn't loud, and hasn't had any issue cutting through various woods at 300mm/min. I did several calibration tests on the machine as soon as I got it built, and didn't have to adjust anything. The only bad things about the machine are the hold-down clamps that are included (they work, but are the definition of "fiddly"), the included Vee bits (again, they work as they should, but why give me a bunch of Vee bits and no end mill?) and the size of the workspace. The 3018 is actually a great size for a small workspace like mine, where it will need to be moved and worked around, but just like everyone else, I'd love to be able to make bigger stuff. I've probably said enough glowing stuff about this device, but I'll sum it up, here. When I spend ~$350 on a piece of Chinese technology that's based on open source designs, I expect to get a pretty low-end product that I can usually upgrade to make it useful. In this case, I got a solid, well-deigned, functioning piece of gear. I haven't been this amazed at how well a cheap gadget works since the Elegoo Mars Pro. If you're looking for a cool tool with a steep, but fun learning curve, look no further. If you want to easily and quickly cut wood (or metal) parts with the push of a button, maybe wait a few years. Software That I Used: -Candle (included) for machine control -Easel (very limited free use) for design and GCode Creation -F Engrave (free) for GCode creation -Carbide Create (free) for design and GCode Creation -Fusion360* (free) for design and GCode creation -Inkscape (free) for image design *Fusion360 is the real workhorse, here. It has by far the most features, but also the steepest learning curve. If you're familiar with Fusion360, you'll have no trouble. Otherwise start with Carbide Create.

Hi guys I bought this router in January and would like to say a few words about my first experience. Ease of assembly You will have no problem. It's really simple. There is a manual and there is a YouTube video. I spent about an hour and it was stress-free. Ease of first use It's fine. Before buying, I was worried about how well it worked. In vain. This is a truly wonderful invention. Thanks to the engineers. And I didn’t expect this complex machine to be so easy to control. Within one hour I learned to work with this router and again had no problems. Problems start with the software "Candle" It is assumed that we all buy a CNC router to create something especial. And this is where the problems begin. If you want to do something that has more than four corners, be prepared to grapple with obstacles. The seller offers software that turns your idea into machine codes. This is Candle. I have not been able to figure out how to use this software. Please note that in the YouTube video someone is using Easel, and not the supplied Candle, which is part of the kit of this router. The complexity of the proposed Candle is high. There is no technical documentation for Candle. Moreover, the supplied Candle does not perform the operations shown in the YouTube video. Try uploading your image or picture from your file... Now I use Easel which is easy to create images. This Easel was created for another router. I spend a lot of time creating any image all the time. Easel often loses the rotation speed of the router and I have to create new files. Easel often does not recognize the text as a whole object and I have to start over an old project every time. But Easel at least creates files for carving. Excuse me sellers, but if you offer software like Candle then this should have a manual. Without a detailed technical description for the software, this router often becomes not a smart machine but a piece of iron. I gave 5 scores to this router. Without a doubt, this CNC router is the best in its class of small routers. I can't give 2 scores to the supplied software just because it is free according to the seller. No problems. I hope my opinion will be useful for people who is decides to buy or no this router.

SainSmart 3018-PROver review and errata - January 18, 2020. The materials provided are good: heavy and well-machined aluminum, acceptable quality electronic and mechanical components and fasteners. The 3018-PROver is not nearly as “assembled” as the purchasing data indicates. You can download the assembly video or the manual and see for yourself - there are a couple of hours of assembly work, and there will be much consulting of the online manual, the video, and this errata while you are at it. The three major subsystems are mechanically assembled, but have not had the electrical components, wiring and many little parts mounted, and two major subsystems need to be bolted together. And since the instructions leave a lot for you to figure out, if you’re easily frustrated: choose another project. The PROver version is based on Open Source software and incorporates its own motion controller software: GRBL 1.1. It does not need to be connected to your computer while the router is cutting. Most people will use Open Source CAD software, which does not come with the unit. There is also a “3018 Pro MX3” version which requires that you purchase the Mach 3 software for $175, has a different main controller board and a different hand controller, and requires a Windows computer to run Mach 3 while the router is cutting. The 3018 PROver is a better choice for most people, as it avoids this expense and complexity. Mach 3 is motion-control software, not the CAD software. You will still need to find that. The 3018-PROver controller is based on Arduino. The main controller runs the GRBL 1.1 software developed for Arduino and comes with its own hand controller. Hand controllers for other models, like the one for the MX3 version, are not compatible. Source code for GPL-licensed software in this unit is not on the SainSmart web site as far as I can tell, and it looks like SainSmart still needs to learn how to comply with the licenses to the GPL binary software they distribute, and directly distribute the source code on their own site. I do not know what differences exist from the GRBL 1.1 developer’s source, but I suspect some might exist for the hand controller. This machine will be covered with chips after operation and will require some wiping down, including passing some sort of wipe inside of the T-slots. I will try to improvise a chip vacuum for mine, no such thing is available to buy. To find the assembly video, search for Sainsmart Genmitsu CNC Router 3018-PROVer Build. A few hits down from the top of the search on Google, there is a wiki page for the device at wiki.sainsmart.com . You can also find this directly on the wiki, but the indexing is based on SKU numbers. There are assembly videos for other models on Youtube, which you might find helpful. Most of the tools required for assembly are provided. In addition, you will need a wire cutter to remove two wire ties used as a shipping lock, and a container of light oil to lubricate the lead screws, and some electrical tape to wrap moving wires together. You will need to download the manual and display it on a big screen. That is the only way you will be able to see the photos adequately to be able to assemble the unit. The photos are in a printed manual provided with the unit, but too small and too low-resolution to tell what you should be doing. Here are the errata I noted during assembly: Step 1: You will need to provide your own wire cutter. Step 2: You are told to mount 6 wire holders, but the photo only shows where two of them go! The video is similarly unhelpful! The second two go on the opposite side, identically to the first two. The third two go on the outside of the frame, on the same side as the stepper motor, opposite the two installed inside. Step 3: The four wire holders mount on opposite sides of the metal piece. The photos don’t quite show this completely. Step 5 and 6: The long end of the distance tool is held against the back of the frame, inside the channel. The last slider nut should be against the end of the distance tool. Because of the distance tool, everything lines up well and the 12 bolts go in a lot more easily than I expected. Step 8: The square projection on the slide nut goes outward. Step 9: Peel the protective film off of both sides of the acrylic sheets. They are clear, tinted blue, once you do that. Hold the sheet so that it fits the shape of the leg of the Y-Z assembly. That is the correct orientation. Put the bolts through from the outside, and put the slide nuts on the other side by hand, one turn only. Orient the slide nuts horizontally, and then push the acrylic sheet to the channel so that the slide nuts insert into the channel. Turn the bolts, and the slide nuts will seat correctly. Step 10: There is an error on this page. Where they specify the Y+ and Y- connecting wires, they actually mean X! The VER- numbers are correct, Y should be X. The main controller is attached to two beams, each of which has four channels. The X- limit switch wire must be run behind the main controller along the top of the bottom beam, looping to the front on the side where the controller has the USB connector. The cover strip goes over the wire on the top channel of the bottom beam. Step 11: It may be necessary to temporarily remove the wire holders next to the limit switches so that there is enough space to insert the plugs into the limit switch sockets. Put the wire holders back afterward. Step 13: There are different plugs on each end of the stepper motor wires. Step 15: By “black cover”, they mean the black plastic nut on the barrel of the emergency stop button. Remove that and the square lock washer. Put the switch into the plate, and then put the lock washer on the switch from the back, with the pointy corners facing the metal plate. This button is unusual: push to stop, twist to release. Step 16: Whew! A lot left out here! You are supposed to pass all of the Z wires through a piece of the nylon braided web to protect them from friction. But the piece I was provided, although it can be expanded somewhat, doesn’t expand sufficiently to do this. I wrapped the wires with electrical tape. Operation Before you connect the router to your computer, you can play with it using the manual controller. This is non-intuitive though. I noticed that the files included on the SD card would run into hard limits (trip the limit switches) if run with the router starting in the home position. You will have to move X, Y, and Z close to the center of their operation before starting. The limit switches are confusing. If you are stuck on a limit, which is sure to happen, run the reset function. Move the stuck axis until it stops again - the limit switch will halt the system when it is set, and again when it is cleared! Run the reset function a second time. Then you can move the axis as expected. At this writing I am not sure if configuration will make this easier.

First off, the caveats. This isn't a $20,000 Tormach CNC or anything like it. However, it IS in the same league of where 3D printers were about 7-10 years ago. If you calibrate your expectations, you will not be disappointed! I purchased this primarily to mill PCBs but also to do a few wood cuts and similar projects. I immediately purchased an upgraded milling motor for future use, as well as the 5.5W laser engraver. The upgraded mill is great for higher-power applications, but the included 775 motor is actually plenty powerful for most engraving and PCB milling applications. If you do upgrade to a more powerful mill, contact Sainsmart for a 3D-printable 52mm bracket - it's the perfect fit for the limit switches. You'll want to purchase 4x LM8SUU bearings (17mm) because the 35mm-long bearings are impossible to find. I damaged mine when I was pulling out the linear rods. Second thing you'll want to do is to resurface (face) your spoilboard. Do this, and you won't need to fiddle with autoleveling the entire PCB or anything like that when milling PCBs. Also, your engravings and woodworking will come out beautifully, same with laser engravings and the like. While the integrated offline controller works okay, this mill is best used with a PC so that you can accurately reposition the toolhead during tool changes. The integrated controller doesn't do a good job there. The depth probe works very well, make sure to replace the included GCode with updated GCode from the manual. The stock probe height is 14.19mm, but I found that mine is actually closer to 14.35mm. Be sure you use a good caliper to measure it. By far the biggest learning curve is setting up your CAD software (e.g., Fusion 360) to work with the mill. However, once you've done it, this thing is super reliable! Same for figuring out things like KiCad - you'll want to make things extra "chunky", by using extra large pads and making your traces larger. I was able to do 0.2mm traces, but those aren't reliable. Instead, I just set 1mm trace sizes and 1mm of clearance, and every board has been perfect. I know it's not ideal for large-scale integration, but that's the wrong application for this mill. Ultimate verdict is this: Take the time to learn this mill's limitations and how to best get it set up. Once you do, you'll be quite impressed. It's easy to set up (the 15 minute setup is nonsense - budget at least an hour), tolerances are quite good, and like I said, it reliably does what you need it to do. At this price, it's impossible to beat this machine!

Although I have not had a chance to use the product yet my initial review will be on it's unpacking, setup and condition on arrival. Was packed securely and when it was received the box was undamaged. Lots of stuff neatly packed in the box. Installation manual was clear with some included videos on the thumb drive. Setup will take awhile but just follow the directions and work carefully and you will have no issues. Everything looked great and went together seamlessly. I stared to set the Z Probe and as the Spindle moved over to the home position and I started to set the Z probe Kit onto the table I noticed a big ding on the top left corner of the table, see the attached pics. Further inspection of the top shows some scratches and scuffs in other areas too. During installation I used the thin flat Styrofoam packing to put the top of the table on to prevent such scratches so I'm 100% sure this is not user induced. Things like this happen and although unfortunate and time consuming (replacements) it's just part of the deal if you are the unlucky one. I don't feel that a used machine was shipped to me but looking at the top and the scuffs and this damage on the corner, it was probably damaged during installation or packing. Either way, I have contacted the seller and requested a replacement bed. I'm ok with that as long as I get a new bed back. I have left a 3 rating for the time being once I get the sellers response and actions I will report back here. Anything less than a "Sorry sir we will get one out to you right away will not bode well". Not asking for a full machine, I'm ok with a replacement bed as long as it's a "New" one. Stay tuned! UPDATE: 17 Jan 2021, So the seller contacted me right away and sent me a bed from China. It was on backorder and is enroute. Unfortunately I had issues with the machine. There is a Z Probe Calibration so each time you place a piece of work on the bed you calibrate the Z Axis with the probe so the machine knows where the surface of your material is. This worked once after that can't get it to work. Sometimes commands are not executed from the machine just when jogging with Candle the software that comes with it. Thought maybe it was a COMMS issue so I tried the offline controller. Same problems. I emailed the company many times, but took forever to get a response, I thought I had fixed the issues by uninstalling the driver and re-installing but eventually the Z Probe Calibration stopped working again. You can calibrate the Z Axis without the probe but why? If it's there I want to use it. Boxed it up and it's on the way back with a new unit to arrive Tuesday. BTW you can't disassemble the machine in 15 minutes let alone assemble it so this is a marketing gimmick about 15 minute install. If you assemble them daily yes you can but as a new buyer you will want to read through the manual and take your time. Think 45-90 minutes to assemble especially if your first CNC. Update 28 Jan, 21. Little bit of a delay in my update but I did receive a new unit. I returned the previous one through Amazon and a new CNC arrived a few days later. This one shipped from a different location. This router appeared to be brand new. Assembled it and everything tested and ran perfectly. I did order a bed extension kit and you guessed it, received it damaged and used. In the process of getting that replaced. So in conclusion, as far as operation, well all I've done for the last 2 weeks is deal with replacing used items purchased as new so really haven't had time to use it. I did mill the top of my spoil board to make sure it's flat. As far as dealing with the company, be warned you have a high probability of receiving used items when you purchase new. Look them over carefully. Not sure if this is Amazon or Sainsmart. If it's Amazon, it's easy to return and just inconvenient. If you purchase anything through Sainsmart, not so convenient and it takes a while but they did replace the bed and the bed extension so I have to give them credit there. I'll leave this at 3 stars due to the headache of multiple returns. EDIT: 8 Feb 2021. So I will make my final review here. I did receive a new unit which works great. I had also ordered a Y Axis bed extension from Sainsmart which arrived used and damaged. Of course I contacted them with pictures and they sent me out a replacement unit that arrived in satisfactory condition. So all in all I have had some bad luck with damaged units and replacement CNC however the customer support has been top notch. So if you do get a unit that is not up to par the Company will for sure make it right. So I will adjust my rating to 4 Stars and have to say that you can purchase with confidence that if you get a bad or damaged unit it will be replaced by the manufacturer. CNC router is together and I'm engraving. Keep in mind, no documentation on how to use a CNC router. For that you will have to go to the Facebook Group, search, read and experiment. Happy Engraving. EDIT: Bonus Content 2/14/2021 I have decided to rate this a 1 star. After I purchased the original CNC router I went to their company website and purchased their laser 159.00 USD. I just now go around to opening it up and installing it and guess what????? You guessed it, there was something missing. The power supply was missing. They sent the power cord which goes from the wall and to the power supply but no power supply. So I have a laser and no way to power it. I Do NOT recommend purchasing from this company. If you decide to sear TUMS you will need them.

I have never owned or operated a CNC router before or even seen one in operation. I bought this to learn how they work and hopefully make some PCBs (small ones). This machine has all I needed to begin etching planar surfaces, including milling PCBs. I first tried to cut some MDF wood and found myself making little circular pine Christmas tree ornaments for all of my family members, setting the PCB project aside by the end of the second day. All of the software needed to CADCAM PCBs and the wood ornaments can be found for free. I settled on Fusion 360 (personal hobbyist license - free), which works well for the wood ornaments and designing the PCBs. I found, after a few attempts, that Candle / GRBLControl (also free) works better for milling the PCBs as it has a height mapping feature. I can’t say enough how much fun I have had this past week learning the ins and outs of the software and manufacturing process. I’ve already ordered the motor upgrade, laser upgrade, and a few sets of milling bits just based on the quality and value of everything I’ve encountered related to this machine and Sainsmart. This will probably be the first and last CNC machine I buy simply because it does everything I could ever imagine doing with one. It may not have the power of production-level machines used in the industry, but it is accurate down to sub-millimeters. I was able to pocket a holder for PCBs of 102x79mm and it did exactly that, without any calibration of the router after I had assembled it. There is a steep learning curve at first, mostly related to the many options of software and parameters related to manufacturing parts. But, if you have used CAD programs before and are familiar with the design process you will pick it up quickly. Looking forward to the 3040 upgrade kit getting back in stock - although I read that there may be problems with compatibility of the laser module, due to the MDF+aluminum bed combo putting it outside of a usable height.

I think its defective and support is really slow to get back to me. The prober function does nothing and I've gone through all the documentation for setting the Gcode and positioning. I bought this specifically for PCB milling and thus it is useless to me without the prober and heightmap feature. So far I'm not impressed with support, it's been a couple days and no information. They acknowledged my question and said it would be 2 or 3 days to get back to me. I'm close to packing this up and sending it back. It's either a bad controller or some stupid simple undocumented setting.... I reserve the right to update this review if they eventually get back to me and can resolve this. I'd really like it to be something simple so I can use it. I have a big 4' x 4' CnC router for wood working so I am not a newbe with CnC. Unhappy Tom Update 6/30/21: So it was a stupid setting. Turns out the soft limits were interfering. This YouTube tutorial, https://www.youtube.com/watch?v=u4Mcjz7IP10 while otherwise very good had me turn on Soft Limits; $20. This seems to be the root of the problem. I can't say if Soft Limit's would have worked with different travel settings as I've not investigated that. I also had a problem with the $90 setting and ended up using $91 instead. I also have not yet tested to see if I can go back to using $90 now with Soft Limits disabled. These are the settings I used: G91G21G38.2Z-20 F100 G92 Z00.00 G0Z2 M02 Note that I have 0 offset for the prober because I am only working with copper PCB and thus I have removed the prober puck and am probing right to the PCB copper layer. The Soft Limit's issue was not SainSmarts problem, I do recognize that, but I do wish they had some better documentation on the the setup and calibration, it might have saved me several days of trouble shooting. At any rate I had success and isolated my first PCB. The heightmap function in Candle was critical to this. I actually like USG better than Candle but USG does not have a working Heightmap function. That's not SainSmarts problem. I have more tuning and testing to improve my PCB work but that all me. The SainSmart 3018 PROVer seems to be a decent little CnC, perfect for what I want to do with it. It's not got a lot of power or working area but that's not needed for the PCB's I'm working with. It's about $100 more expensive than other 3018's but it comes with the emergency stop switch, the hard limit switches and the probe. More importantly the probe connection on the controller. All of which I felt are important. It was pretty easy to assemble and to calibrate. The YouTube video I mention above is a really good tutorial for setting up and calibrating minus the SoftLimit setting. All in all I am now much happier with it and look forward to more PCB projects. I do wood working with a larger CnC machine, I don't know how this little machine would do anything other than engraving, but PCB isolation seems pretty reasonable. Now about support; They are there, I.e., they do have support. They were slow to respond and ask questions but they never actually helped resolve the issue, perhaps they would have eventually but the the help I received was from a member of a GitHub CnC forum. Thanks to ondras12345! I would have given this more stars but for support. I thank them, but they didn't seem to be very interested in helping until I posted the negative review and even now they are more interested in getting me to edit the review to positive. That cost them a star. The product is adequate for the job, seems solid, easy to assemble. Had I not had this issue and/or a better result with support they would ahve probably got 4 or 5 stars.....just sayin. Tom, no longer unhappy

This machine is my first foray into CNC machining and so far this machine has worked very effectively. Being an electrical engineer and software developer did not hurt while learning to use this device. I will admit that it was still a challenge to get all the dots to line up, (i.e. there are a lot of factors to consider when choosing software tools, bits, feed rates, etc.). This required a lot of determination and focus for an old guy like me. But if I can do it you can too. Just don't expect it to be a piece of cake and give up prematurely. Having said that, the machine itself has performed very well. The accuracy is good and I like that it is self contained and compact for the kind of stuff I do. Aside from a small problem with the emergency stop button sticking, everything has worked well. I recently purchased their dust collection shoe that has an excellent design and is reasonable priced. I had a minor issue with it, (that was largely self inflicted), and they were extremely helpful and immediately sent me a replacement. All in all I love the machine and I am pleased with SainSmart support as well.
