It’s a $35 board substantially less than one hundred, and $175 license for mach3. ![]() For my review I installed the woodpecker board from the pro version so I can use CNCjs. Mach3 and Mach4 are pretty much the de-facto CNC software for professional CNC machines but doesn’t make sense on a hobby machine like this. ![]() I prefer to run CNCjs on a Raspberry Pi to control the 3018. It runs on Windows and from my previous experience that is not a good option. Mach3 is the cheaper of the two and costs $175. The board can almost only be exclusively be controlled by Mach3 or Mach4. Of all the upgrades the limit switches and zero out tool are by far the best in my opinion. The instructions were to heat up the chuck and press fit over the motor shaft. I never did install it on the pro version. The kit also comes with the er11 collet chuck pre-installed on the motor. Fundamentally very similar to the pro version. There are also some acrylic pieces in the kit. The MX3 version has a new controller board, Z-axis zero out tool, limit switches, and better clamps to hold material that is being engraved/cut. Okay let’s look at what has been upgraded. I built it on a live stream in a couple of hours with no issues except one where I wasn’t paying attention close enough. Although the printed booklet is a little small the PDF is there to back it up. I really hope the other manufacturers take notice. These are the best instructions that have been provided in all the 3D printers and other Chinese kits that I have put together. The instructions go into a level of detail I very much appreciate. I struggled a little bit to read the small booklet that came with the kit and afterwards I found a PDF on the Sainsmart wiki. Click to Enlarge Buildīuilding the CNC Router 3018-MX3 was a breeze. Most of the experiences and solutions apply to this version. I suggest reading the pro version after reading this one. I won’t go into too much detail like I did in the previous review. The pro version can be found for about $250, and the CNC Router 3018-MX3 for $350. You can find the original 3018 on sale for about $200. ![]() Let’s take a look at the changes and the evolution of the 3018 and see if the increase in price is worth it. Sainsmart has now further upgraded the 3018 and asked for a review of it. Back in September of 2018 I reviewed the Sainsmart Genmitsu 3018 Pro. ![]()
