Fast delivery and easy to assemble. Sainsmart resource centre very helpful

im happy with this. cant wait to make more things

The Genmitsu 3018 Prover comes mostly assembled for the physical hardware and requires a bit of wiring to get everything running. It took me about 1.5 hours from opening the box to running the sainsmart.nc test file. The video that Genmitsu has on the assembly is VERY good. I watched it all the way through a few times and during the assembly, I would pause the video as I worked through the build process.This is a lightweight CNC router with a small work area. For my purposes, this is being used to "carve" wood patterns for green sand metal casting. The Genmitsu 3018 has a very large following and there are great resources that you can find on the internet to help you get started. There are so many upgrades to improve the performance of the machine that it will be a while before I "outgrow" the 3018/4030. You should not expect this machine to make deep cuts and have high feed rates, but it will carve nicely if you take your time.The Genmitsu 3018 prover with the limit switches is less likely to "crash" because of exceeding the work envelope of the machine. It does slightly reduce the work envelope over the "pro" machine because of the switches, but I think it is worth it for the extra protection. I also like that the frame as all aluminum where the "pro" model still has some parts that are plastic. Sadly, the spindle mount/z axis is plastic for both pro and prover models, but there is an aluminum upgrade available. This is probably the weakest part of the machine.The spindle motor that comes with the machine is limited to 10k RPM. There are upgrades for the spindle that can get to 20k RPM or higher torque.I am super happy with the purchase. The very fast shipping by Amazon was great. I would recommend ordering some additional carving bits as the machine only comes with ten 20 degree V nose bits that are best for engraving. I picked up some straight bits and some ball nose ones to carve curved surfaces.Important safety tip ... be careful when reaching into the machine with a cutting bit in the spindle. The engraving bits are very sharp! (Don't ask how I know this!)

I purchased this product about a month ago but only opened it on Christmas day. It is made of a sturdy material and fits together really nicely. I am pleased with the quality of the material and the workmanship. I do have a lot of learning to do as I am just starting cad. I still need to learn cam and g-code and maybe more. It should keep me busy for awhile.

This the first personal unit I've ever owned. It took a few hours to put together but everything was easy enough to understand. The tolerances are tight and it feels high quality. Some reviews mention things like the pieces not being the advertised blue or needing wire cutters but the kit I got had everything!If you plug it in and it connects to Candle but nothing works make sure you check your emergency button. It's a special kind of switch that's spring loaded so you can't pull or press to release. To release it you have to twist it in the directions indicated in the arrows before it will pop back out. I wasted a good hour on this step by not lookingcarefully! Whoops.I was also concerned about the amount of sound it would make in an apartment and was glad to find that if you can control some of the vibration it's quiet enough to use without bothering the neighbors.The software and manuals all worked fine and there was a copy of the software and tutorials on the included SD card for the offline controller.

Be patient. Love this.

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.

Router has performed as expected, it��s not an industrial unit but it does have a lot of flexibility. What has most impressed me is Sainsmart��s service. I had an issue they responded quickly and replaced the component without issue.

this is a great machine, built very well. opened box put it together about 2 hours, fingers don't work well now a days. installed my settings and off i went
