You are looking at a DIY kit of a CNC carving machine. Now you can build your own very first CNC carving machine to make relieaf carving, letter cutting, inlay and all other interesting features to enhance your woodworking PCB, or other projects.
The body of the machine is constructed with PVC board and steel linear bearing guides and stainless steel lead screws. All three axis are equiped with aluminum flex coupling, brass anti-backlash screw nuts, and used Nema 17, 2 phase, 6 wire stepper motor. After a proper install, you will be amazed by what can be achieved by this machine. It can also provide a beginner CNC hobbiest an oppotunity to practice all aspects of the CNC world with very reasonable budget. After you become more comfortable with the concept and complete a few real projects, you will know what you exactly want when it comes to purchasing a higher end machine within your own budget.
In order to run this machine, you will still need a power supply (24V DC), a 3 axis stepper motor driver, a PC and a dremel cutter, which are not included. Those components can be easily acquired from the web with very reasonable price. Also, you will need software to run the G-Code that generated by any CAM software you choose.

Zen Toolworks DIY CNC Machine Review:
Short reviews are great but I decided that mine should be a bit longer and in depth so anyone who reads it will have a better idea of what exactly a Zen Toolwork CNC Kit is. In short It is a GREAT item. If you want a short review see below.
Short Review: A Must have. One of the Best Investments I have ever made as far as tools go. Buy it!!!
Long Review:
A MUST HAVE for anyone who wants to get started with CNC with an excellent well made precise and affordable machine. If you want to design prototypes, carve foam, plastic metal or wood (this machine is perfect for doing wood engraving as it has a fantastic detail level even when down to extremely small designs with the right bits) or even if you just want to make small custom and/or precision parts on occasion for models or RC vehicles; or perhaps just do a little custom engraving once in a while this machine is more then able to handle the task without emptying your wallet. And it's a Kit! So you get to have a great time building it!
Arrival: From the time it shipped to the time it was at my door was 2 days. I live in NJ and the CNC kit came from CA so that was very fast shipping!!!
Upon opening the box I found everything very well packed, very tight and secure. I did a parts count and everything is where it should be with a few extra screws, bolts and washers.
Parts:
The material that makes up the body of the machine is very strong. Much stronger then I would have initially though. The box must have weighted in at over 40 pounds, as the body material is very heavy and sturdy. Anything that was not made of the gray body material (such as the driver screws or the rails) was steel or stainless steel.
Quality: All parts except the motors are brand new. However in the description it does say that the motors are used. Considering that the Stepper motors are probably the most expensive part of a CNC machine this is where the real savings are as the motors while used are very well made and appear to have a lot of life left in them. I don't think I will be burning out any of these 3 motors any time soon. So everything came as described or better. For the price paid the quality can not be beat and surpasses what most people would expect for a CNC machine priced well under $1200 even under $300 as Amazon has them listed at an absurdly low $299.95. As far as CNC machines go less then $300 is near free when you compare it to others of the same size. This machines ability appears to on par and in many cases better then the "cheap" desktop models others are selling for $1100 on up. After building it and seeing what can be done I can say that this is one of the best deals out there for any type of CNC machine or tools. All moving parts have multiple ball bearings so nothing is dragging. Even after reading all the positive reviews I was still pleasantly surprised at the sturdy design and well made parts.
Ease of Assembly: All you really need is a cheap Walmart $1 Hex Key set, a small vise, a Phillips screwdriver, a power screwdriver (saves a lot of time but not really needed) and some common sense. Total tool cost for what is needed to assemble this kit if you don't have any tools at all (everyone has screw drivers right?) would be less then $30 and that is with a cheap power driver or about $10 to $15 without the power driver. The tough part is getting the small side of the driving screws to fit the ball bearings as it is a tight fit and they need to be pressed into the bearing. I found it easiest to get the driving screws into the bearings first as I do not have a drill press handy (a cheap $40 one from Sears could do it) and then use a small vise to gently press the edges of the bearings into the body parts. If you have access to any kind of drill press this can be done really easy using the press to put the driving screw into the bearing after it is in the body. It took me about 4 ½ hours assemble and I had to back up a few steps because I forgot to check the alignment of a few holes (this means I put a few panels on backwards because I was not paying attention) and had to disassemble a few steps back to reposition a few of the body parts about 3 or 4 times. That was my fault however. The only customization that needs to be made is a mount for your cutting tool. I have a dremel tool so fabricating something was easy enough. Even a quick fix however would be fine because once attached you can use the machine to make a better mount. I will say I had a great time just building this machine. I am already tempted to order another one just to build it. Maybe I can talk a few friends into buying them and letting me do the assembly. Everything was easy and well made and fit where it was suppose to fit. When you read the online instructions for assembly it says that you should take your time and it does not have to all be built in one day but once you start you just get into it and have such a good time that you really want to finish it all at once. This was a 0% frustration build and very fun.
You will still need to buy a power supply and driver card but they can be found cheap online. You will have to make your own interface cables for the driver to talk to the motors but it only takes about 10 min a cable (You will need 3) if you want to wrap it nice and make sure it is all insulated. This is the one area you don't want to be cheap on price or time about (I spent about an hour doing cables and about $10 for wires, tape and connectors at Radio Shack. Get the color variety pack. It helps to color code). If you cross a line you could fry out your board or your stepper motor so make sure everything is separated nicely and insulated well. Most importantly make sure you have a male/female Printer cable! I did the whole build, wires and all; and at 1:30am I was looking forward to a dry run with just a sharpie to check out the level of details that can be done and to make sure everything was working correctly after building the unit and getting all excited about running it when I realized I had no printer cable. Plus it was snowing so badly that everything was going to be closed the next day so I had to wait a few days to get one. These are all over EBay if you just type "CNC Cable" in the search so if you don't have one you can get one shipped for less then $10 if you look online. If you have any mom and pop computer shops nearby they may have one there if you look and odds are it will be free or only be a few dollars as the cables are not used much and just take up space. Everything went together really easily. Electronics as well.
Size: This is a desktop CNC Machine so it is small enough not to be in the way, about the size of a large desktop laser business printer or about 1 ½ times the size of a desktop printer/scanner/copier and 2 times as high; which is great if you do not have a lot of room. I currently have mine sitting on a rolling laptop table and it takes up about 60% of it. 100% with the card and power supply but that is because I have it mounted to a Plexiglass base as I am in the process of building a housing for the electronics) Do not let the size fool you however. The work area sounds small on paper but once it is built there is more working room then initially thought. There are many things that can be fabricated with a machine this size that would surprise you. If you check out Youtube there are some good postings of some of the basic things this machine can do as well as a great video of a detail engraving on an aluminum block. While Zen Toolworks appears to be a young company and this CNC machine is still a fairly new product, I expect to see a lot more of these videos soon as it is the least expensive machine you can buy and one of the best investments anyone can make for their shop. This desktop CNC Machine is just big enough to make almost anything you could want a small 3 axis CNC machine to make in the work area AND the worktable is raised enough so that a larger then 7x7 item could be fabricated and/or engraved in sections without the frame getting in the way. It is small enough to be out of the way if you have a small shop or even an apartment with limited working space.
Level of Detail: The first thing I did once I got the machine built was to use a small metal bar and attached it as a mount with some screws to hold it in place and some zip ties for a pen so I could do a test run on a sheet of paper. I used Mach3 and jogged the unit manually to see how accurate it is. Jogging produced a good level of detail but the small amount of time that it takes to tap a button doesn't allow for a real test of the machines detail levels as you can not get really fine levels just manually jogging the machine. So the next thing I did was to use Mach3's Lazy Cam feature and just typed out my Fiancés name, picked a font and did a drag and drop. It took about 5 min to do the 8 letter name. I had the machine set for a fairly small font with the lettering outlined so it was a hollow letter which is why it took that long to make. The font size on paper would be similar to a #10 font size if you were to use a printer. Just using a cheap pen and only being held in place with zip ties I was able to produce an extremely accurate and very fine level of detail. No misses, skips or miss alignments. It doesn't sound like much but considering the small size and type of font once you see it done it is very impressive. To get an idea find a hollow text font and in size 10 print out a name. This machine did that with a pen and with a much thinner line going point by point without missing a beat. Let's say that after that I was very impressed. Not only was it perfectly drawn the round parts of the path where actually round and not just short lines. Next I found a Dragon image I liked so I used inkscape to create a Vector path and had the machine draw it out. It was a fairly detailed path and again it was hollow like the text so each line was really 2 lines and every object had a border. Total time was a little over 27 minutes and the detail level again was excellent and very surprising. I am very impressed and the fine level of detail that can be achieved with this machine and it is more then worth the price. Again one of the best tool investments I have ever made. The level of detail is far better then I expected even after reading the other reviews and I plan on doing some wood carvings this week. If you have to do any engraving, prototyping, fabrication, light production or 3D carvings especially in wood this is the best you can get without spending several thousand dollars.

The kit got to the east coast in lightning time. The kit is very well manufactured, and relatively easy to put together. The documentation is new, and a little lacking, but Zen has already made improvements in the week I've had my kit. You are buying this from an American small business owner, who must spend all day on Google supporting his product. If you have a question, it will be answered directly by him, in less then an hour. It is also supported via Google groups with a forum of some knowledgeable people as well, it's very newbie friendly.

I ordered this item from an Ebay auction. It came packaged into a small USPS box, carefully and neatly. All the parts were there with extras as well.
It took me about three hours to assemble it. Make sure you have a good vise with at least a 3" jaw to help you set the bearings and bushings. Keep an eye on the orientation of the parts as well so you only have to build it once :) The online build guide is well thoughtout and easy to follow. And the online community is active and ready to help.
My goal was first to build a model CNC mill. To start from the beginning and learn as much as possible. This kit certainly did that for me. Once finished, and under computer control, I stuck a small pen into the spindle and did some lettering with serifs. Even under high magnification the curves and tips were perfect. Very accurate and capable unit!
Ive been cutting foam now for casting molds and just happy as can be. The performance is good, the accuracy is high, and its just plain fun to watch it run. Plus the kit aspect makes it even more fun :)
Thanks again for the coolio and fun project! The price is outstanding for the educational value of this kit, and when your finished, you get an outstanding tool for your workshop too boot!

This kit is great for any beginner or for parent/child projects. First build the cnc from the kit and then use it to make hundreds of fun projects you can do any rainy day - or anytime you want to drag the kids off the game console to see their very own cnc carving robot at work ;-) I've used mine for carving pine derby style race cars, fishing plugs/lures that look like real fish and work better than anything else in my tacklebox, a wooden-gear clock, 3D animal figurines, 3d puzzles out of hobby plywood and more than I originally dreamed a machine this small could make. It's amazing!
