De compleetheid van het cnc bouwpakket is verbluffend goed verzorgd. Alles mooi gesorteerd en deels geassembleerd. Met wat oefening is de cnc snel in elkaar tr zetten. Ben er blij mee.

I had this product for a year. I used a lot in the beginning and then put it off as I was busy with other projects. After a while, I came back and worked on this machine and something was not working. I contacted the customer service. After a day, Hong from Sainsmart, provides me a list of diagnosis methods. I tried all of them, did not work and sent him the screenshot. The next day, Hong informed me that he was sending me another control board for free as it was covered in the warranty. He also followed up with me when my new control board came and checked if everything is alright. Excellent customer service.Also, the machine is super easy to assemble and the limit switch on the x,y, and z axis make it very safe. The spindle is pretty powerful and can do some damage and it can also cut some thin aluminum. (You need to go very slow).The one thing that this machine can improve on is the instruction on the programming side. As a beginner, I spent a lot of time and installed several programs (including freeCad) to start to cut my piece.At the end, I found the easiest way is to create a simple text file and type the G-Code myself. If there is simple instructions/examples on G-Code like G0, G1 and G2, it will make a big difference to get a beginner started. As beginner, I just want to cut a straight line to test it out, but I found that it was a lot of learning and time using freeCAD other CAD program to do such a simple thing.

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.

Perfecto todo

I bought the SainSmart Genmitsu 3018-PROVer after lots of research, because it had a number of safety features (end stops, emergency stop), the off line controller and Sain(t)Smart was proud of their support. Spending this sort of money, you don't want it standing on the shelf because something isn't quite right...I bought also the enclosure Genmitsu Acrylic CNC Enclosure - Enhanced Protection, Dustproof, Noise Reduction, the laser unit (not yet tried) and a few bits.Putting it together was quite straight forward with the help of the manual. There are also quite a few videos on the web explaining the process.The tricky bit is to work with it, as little errors will upset the process. The worst so far is that I broke a bit as the speed of the spindle wasn't quite right. The machine is not intelligent, so if you give the wrong instructions, it will do the wrong actions...Support of SainSmart is brilliant, quick, helpful and patient. There is also a user group - although it is on Facebook :-( - and loads of good material available on the web.I've 'designed' my first item (a box) on fusion 360 and now up to a more sophisticated model...
