What is an OX?
An OX is a CNC (Computer Numerical Control) cutting machine used for cutting various hard materials, such as wood, composites, aluminum, plastics, and foams. So instead of routing your material by hand, a CNC router allows the tool path to be controlled via CNC and you get to sit back and watch the magic happen while your machine performs the grunt work.
Why do I need one of these machines?
If you are a maker, hobbyist, crafter, or just a “tinkerer”, then this machine is for you! His and hers projects combine to bring a fun, money-making experience to your household and/or workplace. From furniture, sign making, and home décor to musical instruments, prototypes, and RC parts, the sky is the limit to what you can create!
What do I need for this build?
Spoiler board, USB cable, and a computer (Raspberry Pi can be used).
Assembly tools included. No drilling, tapping, or soldering required.
With all of the CNC Routers in the market today; why buy an OX or R7 from SMW3D?
This build a direct descendant of Mark Carew's awesome OX CNC build.
The build instructions can be found here. This is a google version, some editing may be lost; for best viewing download in word.
1. What exactly has been revised from the previous machine build?
Answer - There have been several changes based on feedback over the years and some items we just never really liked about our kit. All kits come with machined spindle clamps, full wiring that does not require the builder to solder connections, no drilling and tapping is required, a new size was offered(1500 x 1500), homing switches were added, spindle speed control is standard, entire electrical system runs on 48VDC and can be powered by 100 or 220VAC, controller became standard with loaded profile for the build, all wiring provided is shielded, X and Y cable chains are now standard, and a few other small changes. All in all this brings a very sturdy and complete kit to the table.
2. What else will I need after I build this machine and hook up my computer?
Answer - The controller is a GRBL based controller, you will need to speak to the controller somehow. This is done through a variety of different programs, such as bCNC, CNC.js, chillipeppr, and a few others are available. Best of all they are free to download and use. Most of these programs will work on a RaspberryPi.
3. Is there a lead time on the build?
Answer - The lead time is based on volume we typically have a kit shipped in 3 business days.

I'm only half way through the build but it has been easy and so far seems really sturdy. Only complaint is that the 1000mm rail was damaged in shipping and I'm still waiting a response from my email to them about it. I agree with the other posts that having everything bagged for each step is a hugh time saver Can't wait for this machine to be up and going.

I am amazed at how easy it is to put together an OX. My only complain is with the instructions. I think they are poorly written with too many assumptions. I've never done anything like this - I mean building electronics- or any mechanics - I'm an artist. But once I figured it out the configuration falls in place nicely.
Very Solid Kit, Loved building it

I bought this kit as a Christmas gift for my teenage sons and myself. This is the first CNC/3 axis I've ever had, so I figured I'd get a kit and hopefully minimize the fool's tax. I'm very happy I chose this one. It is an excellent project. The materials were well cut and the design is quite rigid. All the little screws and parts are bagged and clearly marked, which is HUGE for a project like this. There are a few thing that could be improved that I'll note at the bottom, but in spite of those, I'm extremely happy. I'll also note that I picked up just about every upgrade available.
Here's some things to be aware of if you haven't worked with openbuild systems:
-You'll need an M5 tap and a good ball-end hex set for the build. I found cutting oil to be very helpful.
-This kit is a piece of hardware, and the hardware build is well documented, but the controller board(tinyg) and software to run it are not. There IS enough documentation to point you in the right direction. This was a bit frustrating because I was starting at zero knowledge. To clarify this point, my kids and I had the router built in about two days, but it took about another three weeks to get all the software located, set up and tested. This time included a number of configuration trials. If you are already familiar with CNC software, this would not be a problem for you at all.
-This forum post was essential: http://www.openbuilds.com/resources/how-to-setup-configure-an-ox-cnc-controlled-by-a-tinyg-v8.146/
My one serious wish for this would be the inclusion of limit switches, or at least predetermined mount points for them. I'm working on a setup to cut circuit boards, and am spending way too much time figuring out the best place to put a set ( the z-axis is particularly troubling). The second wish, would be the inclusion of some extra t-nuts/screws and notes _early_ in the build of where to possibly place them for adding things like mounts points for the circuit boards, or clamping systems. Third, and this is very minor, would be an option for a better belt tension system.
I want to take a moment an mention the customer service. I ordered this kit a couple of days after the posted Christmas cutoff, but it was still shipped in time. Kudos to the whole crew for that!
We are VERY happy with the CNC. It is an excellent design and the parts are high quality. You won't be disappointed!
Best small CNC for the money

I purchased the Ox CNC will most of the options, making it a "Big" Ox with the 400 watt spindle. I have been building it part time for a couple days and have most of the assembly completed and working on the wiring. The kit is very well organized and this allowed me to complete different stages of the build out of sequence. The parts are of very high quality and I am certain the CNC will perform very well. There are a couple minor changes I made to the included materials. I picked up longer bolts that were included, to go into the ends of the extrusions. Since the hold strength of aluminum threads isn't nearly as good as steel, I tapped the holes 20mm deep and used 16mm bolts. The kit included two "spin-in" tee nuts for the clamping the belt ends to x axis carriage. I found these very difficult to install so I picked up a couple of the standard tee nuts like were used for the rest of the machine and found them much easier to deal with. I did manage to remember to install Tee nuts in the Z-mount to attach the spindle thanks to one of the review comments. The instructions didn't mention it so reading these reviews can help with the build.... Other than those minor items, everything else was great!!! Cudos to the SWM3D team for putting together a fantastic kit!

I purchased the large-OX and overall, I am extremely impressed with this kit for the price.
The only real negative was that the two bottom holes in the rear plate for my X-assembly were not milled all the way through. These holes take eccentric spacers for your two bottom wheel assemblies and I had to drill them the rest of the way out. Not really a big deal, just an inconvenience.
Also, the spindle mount kit came with regular T-nuts (not drop-ins) which required me to remove the bottom plate from my Z-assembly after it had been mounted to add the T-nuts. Again, not a big deal,... just an inconvenience.
I will mention that there was not enough wire included with this kit to properly dress the machine out unless I mounted the controller board on the gantry somewhere.
Since I wanted my electronics positioned separate from the machine, I needed some additional 22/4 wire and I also ordered a second (larger) drag chain for the cables to run along the Y-axis.
The drag chain I ordered for the Y-Axis I ordered a little larger since it needs to support wires for all 4 steppers, the limit switches (which I also ordered separate from Openbuilds) and the spindle. For that many wires, the larger (15x30mm) cable chain was much easier to work with than the 10x15mm that comes with the kit.
That being said, I am extremely satisfied with this purchase. I had been thinking about building a CNC for about a year and had priced out most of the parts and can tell you this kit is an exceptional value.
Having everything shipped in one box, not having to source parts from multiple vendors, Etc,.. is a huge convenience and one that SMW3d could charge a premium for.
Instead, they did all the leg work and now provide a great kit at great price.
As mentioned, the kit was packaged nicely. In spite of my box being pretty beat up all of the parts were in excellent shape.
The instructions included were nicely done and made assembly fairly easy.
I do recommend purchasing an M5 tap bit if you want to avoid sore hands from manually tapping the 24 or so holes that need threads.
Build this thing right and it is SOLID.
Make sure you spend time ensuring your frame is square and your spindle is mounted true and this thing will give you excellent performance.
This kit really cannot be beat for the price and I highly recommend it.

Everything I needed was included with the kit, laid out according to steps and packaged carefully. Frame members and plates were precisely cut. All of the electronics work perfectly. Instructions were included and they were very helpful. I am very happy with how the nearly completed machine is turning out.

I just received this kit (large kit) a couple of days ago and have been assembling it at a leisurely pace in the evenings after work, I don't have it completed as of this review. First impressions of the overall package are just WOW, packed very well and amazing attention to detail. I'm sure this could be pieced together for less than the cost of the kit, but I personally would rather spend a little more to help support an American small business with a great product. The time saved and the convenience of purchasing everything (everything sorted by step and well labelled at that!) all at once from one source is more than worth it in my opinion. Everyone I have talked with over at SMW3D has been fantastic and extremely helpful with pre-purchase questions and communication during the order process. At the time of my purchase there were supply issues with the TingyG controller, the situation was handled promptly! My thanks to Brandon, Lauren and the whole crew over at SMW3D!!

this is a very good, well thought out kit. The manual can enjoy some improvement. For example, on page 20 eccentric spacer is shown on the right side of the gantry plate, but instruction suggested to install it on the left side. Would be a little simpler to take an inventory of the part received if bags are numbered consecutively. Other then that it is an awesome solution for anyone who needs a good and reliable CNC machine.

This kit came well packed, The included instructions were well written and easy to follow. The parts were packed in separate bags and labeled for each step of the build. Finished the mechanical build in two days. Highly recommend this kit, it takes the hassle out of sourcing all the parts on your own.

After doing a little bit of research I decided to order the OX. The communication from the SMW3D crew was great, they answered all of my questions almost immediately. When the kit arrived, I was impressed with how the kit was packaged and the instruction booklet provided. The kit had a few spacers missing that SMW3D was able to get in the mail the next day. After using the OX for a week or two I ordered most of the bits offered on the site and am very happy with the kit. I am using the tinyg board with the chilipeppr webapp, it really helps having access to a 3d printer for making brackets and a board mount. I would recommend this kit to anyone interested in DIY CNC.
