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 5 business days.

New Kit is Outstanding (2)
Posted by Dale Maxim on Aug 15th 2017
I've finished the wiring and started up and homed the machine. The wiring part of the instructions are more than adequate to do the job. There were a few minor changes for Brandon to make to help clarify the procedure but I was able to do this part without any difficulties. Brandon updated the instructions to a Word document that clarified most of the confusion. All-in-all a great kit that I really enjoyed building. The one hurdle to get over is the marriage of the software (chilipeppr or CNC.js t) to the the M 1 controller. I will be doing a write-up of my build in the forum under revised Ox Build section. I recommend you read that because it will walk you thru this hook-up that Brandon and I did ( mostly Brandon). with either a XP computer or a Windows 7 or 10. You will need to know which windows you have , a win32 or a win 64 processor. Windows properties tells you that. If it is an old computer it is most likely a Win32. Newer most likely a win64. If it doesn't tell you it is a win32. Other operating systems I have no experience with so I can't help you. The two operating programs are free and you will need to pick one. Again in the forum I'll discuss that. One final comment; you can buy a cheaper Chinese machine but it will be no where near the quality and in this arena I've found you need support for whatever you purchase. If you speak Mandarin you can probably get away with cheap. The support you will receive from Brandon's company can be worth the cost of the machine.
New Kit is Outstanding

I am one of the early builders of the revised kit that SMW3D have brought out. The packaging, design, and support make this a great kit to build. You can't go wrong if you buy this kit. It is very rigid and I can see why they call it an OX. I have completed the mechanical portion and have completed about half the wiring. The directions are excellent with a lot of pictures. They also include all the tools to build it, but I would highly recommend a power drill for running in the self tapping screws. If you don't have one borrow your neighbors. It is worth a beer. I can't say enough about the support that they provide. Brandon has been great. I will write the balance of the review when I finish but if the rest is like what I have seen I will be impressed. Brandon- outstanding job.
Solid and fun

I have been using my Ox for a few weeks now and have been having a blast.
The installation was pretty easy and the online videos were a great help. The written instructions are OK but people that buy these things aren't helpless and enjoy trying to figure things out.
I found the 400 watt spindle to be a little small for what I was doing. I ended up going to a De Walt 611 which is great. This is not a hit on the original build it just a statement that I needed more oomph. The 400 watt spindle is smooth as silk and quiet. Getting the motor controller to work properly took a little time and experimentation. There was a cold solder joint on the controller board that gave me a slight headache. The max RPM I can do is 11750, a little short of the 12000 the spindle is capable of. Not sure if there are adjustments I can make to get the extra but it was working fine this way.
Getting the alignment correct was pretty easy and my work area is very square. Just take your time and double check everything as you go.
The Y axis side rails are connected to two X axis rails using triangular brackets. Because they are triangular they protrude into the ends of the bed area. While they are not in the cutting area they do prevent attaching a full width board that would extend outwards. I noticed in the pictures of the current OX that they aren't using the triangular brackets now. I replaced my brackets with L shaped brackets made from steel carpenters squares. They allow me to make more connections onto the Y and Y rails and are very solid. My bed now protrudes about 6 inches in front and about 4 in back. Since I frequently cut longer material for signs I like this overhang. I also use 48 inch slotted channels for clamping. I used holes with threaded inserts at first but found that there just wasn't enough flexibility for clamp placement unless I used a bunch of them. Eventually I will probably build a vacuum table.
I also used angle brackets on the rails between the two Y rails and screwed the whole thing to my table ONCE EVERYTHING WAS TOTALLY SQUARE. Nothing moves.
This motor wire is not twisted or shielded which may or may not be a problem. There are some people that have seemed to have issues with spurious electricity affecting homing and limit switch operation. My original build used the wires that came with the kit and I didn't have any issues. Since then I have upgraded all my wiring to twisted pair and have no issues.
I also suggest that you create a central grounding point near your power supplies and attach ground wires to the Y axis, X axis, and Z axis assemblies. Without grounding I was able to measure a DC and AC voltage difference between Y, X, and Z. The grounding took care of this. Make sure that you have a single grounding point and take care not to accidentally create ground loops. A ground loop becomes a sort of coil and a coil can have voltages induced in them from wires running near the coil that have current running through them (like your motors).
Amazon had a computer case tower with fans (no power supply) for about $25 that I bought and use to house all my electronics. This works wonderfully and I have my central grounding bus in the chassis connected directly to the ground from my 120 volt input line. Some people mount the spindle controller directly to the Z axis but I placed this into the chassis and send the two wires from the chassis to the spindle. Works great and keeps the Z axis assembly a little lighter and cleaner looking.
I also bought the TinyG and use Chillipeppr to control the Ox. I have some issues with the TinyG at times and have to be careful. Sometimes what I see in Chillipeppr is not what is actually happening with the controller. I am figuring this out as I go but have to be careful. This has probably been the biggest learning curve for me. I am actually thinking about going to a different controller.
Chillipeppr is pretty good and it is free. The support for the product is quick and always helpful. If you are into programming you can modify Chillipeppr to what ever you want.
The support from SMW3D was great. My original order included the wrong power supply for the spindle they sent and they sent me the replacement spindle immediately. Since it takes awhile to build the OX there was no delay.
I am quite happy with the product and am always futzing around with it trying to improve things. (like the brackets and wiring).
For the most part the OX is large enough but I will eventually increase the Y axis a lot and the X a little. I will likely go to the C beam on the Y or double up on the regular V slot. I will also directly attach the Y axis to the table.
As you get into this CNC stuff you will assuredly see things that can be done better or things that you can add. If you use a De Walt 611 it will blow dust and chips all over the place because the 611 blows air toward the bit. It can really put a lot of junk into your belt channels and throw stuff out the front of the machine. A lot of people buy or fabricate a dust shoe with a vacuum attachment, which I have done. This makes a world of difference. If you use the normal spindle that comes with the OX this isn't such a big issue. Some people make a deflector that forces the blowing air upwards but this has a tendency to reduce the area near the collet.
I can honestly say that I really like the OX and am having a great time with it. Every day is a learning experience and that is probably the best part.
Would I recommend this to a friend? Yes I would and I would suggest that they upgrade the wheels, belts, and spindle in the beginning. I would like to see SMW3D add an upgrade to better wiring as well. However, the wiring is easy to fix with a trip to Lowes or Home Depot.
Overall, there is very little negative to say about this product and I'm happy I bought it!
Easy build, great value.

My Uncle and I (Buildbotics LLC) built the large format OX together, on film, in about 6 hours. We had a couple of hiccups, like breaking off a tap in one of the holes, but for the most part, things went pretty smoothly. The instructions could be improved but writing instructions is hard. We purchased several of the upgrades which had slightly different build requirements. These differences were not clearly documented. Despite a few deficiencies in the instructions, we are very happy with the results.
We purchased the OX in order to demonstrate the Buildbotics CNC controller. The machine runs smoothly and we are easily able to hit velocities of up 56k mm/min (2.2k in/min) with the stock 24v power supply and NEMA 23 motors. We got it all on video. Look for this and more in our upcoming Kickstarter campaign.
A special thank you to the SMW3D crew for making sure we got the parts in plenty of time for our video shoot. Thanks and keep up the great work.

This is a great product. It comes with everything you need to start a project EXCEPT a router bit, I assumed it came with at least a cheap 1/8 bit, I was wrong. I would recommend buying some limit switches but that's not a must. Unless you are having all your components real close to the OX (like 1 foot) you HAVE TO buy more wire. I set up my tinyg and PWM about 6 feet away and it took 30' of additional 22-4 wire. My only big complaint is that the directions aren't very clear, it's been brought up in other reviews and I have to agree completely. Do yourself a favor and file down the drop in t-nuts in half if you upgrade to gt3 belts otherwise It just won't fit and make sure to put in 4 t-nuts on your z axis before you put on your bottom plate. The instructions don't meantion anything about it until you need to put on the spindle then you have to undo what you just did just to put on the included regular t-nuts (should have been drop in t-nuts). Last thing is there is no info on how to wire this up or what programs to use. YouTube "Setup and overview ox". It's 4 videos from a guy and gives you plenty of info to get you started.
OMG! ONE BOLT WAS SHORT!
Posted by Nathan C. on Dec 21st 2016
This was a hoot to put together. Excellent packaging, good instructions, well-prepared.
I have limited experience building anything like this - a decent background in electronics and ability to solder; that's about it. I was super excited for the kit to arrive, and it took a bit longer than I'd hoped, but these are custom kits, and with the attention to detail, I'm not even remotely surprised. I laid out all the parts and pieces as detailed in the instructions, and got to work. It took the better part of a week of evenings to get everything assembled, not counting any electronics, but I worked slowly and methodically. There are a few minor hiccups in the directions wherein I had to really lay things out in my head and physically so that I understood, but once I walked through a few times, it went perfectly. The only snag was that I had a single short bolt (out of literally hundreds and hundreds), but a trip to big-box got me what I needed. Since that's literally the only thing I could complain about if I were to, this kit gets a full 5 stars. The attention to detail was impeccable, and sincerely, though it's not for the faint-of-heart, I don't regret a single penny spent on this.
The last stage - the electronics - are also not for the faint-of-heart. There are some great videos and guides online about wiring them up - it would be great if they were laid out or sponsored by SMW3D, but it's also understandable that each kit can differ, and there are too many permutations to make that scalable. So, it's pretty much left up to you how to wire, how to route wiring, where to put control boxes, etc. With the detail on the mechanical assembly, it was shocking to not have that on electronics, but you've made a great accomplishment when it fires up for the first time. The software - I stuck with free options now of JSCUT and ChiliPeppr. They work fine.
Good luck! You'll LOVE this kit, and you'll learn more than you expect.
Amazing Product! Fun Build!
Posted by David Tilbury on Sep 28th 2016
I ordered the large Ox and within a week I was cutting projects. For being my first CNC build, I expected more problems and days of troubleshooting. Surprisingly not the case with this SMW3D kit. Everything is bagged and labeled. Super easy build. Even the electronics, wiring and settings can be found online. If you want more detail than they give you. Needless to say, I'm one happy customer!
Just as info for those thinking about this build, Chillipeppr works great with Easel as your CAD/CAM. It will create your Gcode for Chillipeppr to read and cut. I know there are more programs out there, this just got me started with images...still researching. Researching is part of the fun with this little hobby.
Great kit for a a great price
Posted by Martin Masson on Sep 4th 2016
I think SMW3D have kit on the market, sourcing all the parts separately would be be super expensive if you include the shipping fees. I was able to build the kit in a couple of hours. Make sur you have strong enough stepper drivers or it just won't work. I use an Arduino with a GRBL shield and DRV8825 stepper sticks (make sure you have more than enough cooling) and will probably switch to DQ542MA.
solid kit great people
Posted by James Hayes on Sep 3rd 2016
The kit it self is a solid kit well designed. The people behind it are what makes the difference. Any issues you may have the people at SMW3D are great to work with and very timely on responses. I got my kit at 12 on friday and 6 hours later it is mostly built just need to wire up all the electronics. Far better value than the kits you find on ebay or even entry level commercial machines that cost 4 to 5,000$. A++ kit and group.

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.
