Product Description

Raw 1.5 CNC kit 990x990cm with belt drive for pro or hobby.

We only sell a few of these kits as imports are severely limited. Some parts take a long time to get and the delivery time is between 2-3 weeks at the moment.

This machine is very strong compared to other CNC machines in this price range. The machine has steel reinforcements and quality parts and a real Z-axis construction.A complete Raw 1.5 weighs between 40-50 kg and is not made of weak plastic parts and 6 mm thin timing belts.

Steel Reinforcements
Raw is designed so you can reinforce your machine with steel to make it super strong. A steel bar for the X-axis is included in the kit. Reinforcements for the Y and A axis are not included in the kit and are not needed for smaller machines. To strengthen the Y and A axis, you need a 40x40x3-4mm angle bar. Look at the drawings for instructions when you receive your kit. The Y and A axis need reinforcements for machines longer than 100 cm. When the steel reinforcements are in place, a Raw 1.5 is so strong and sturdy that a full-grown person can stand on the X-axis while cutting. Angle steel can be found online or in a well-stocked hardware store or construction store.

Racks or timing belts?
A raw can handle both. This kit comes with a complete set of timing belts with pulleys. Timing belts works very well for machines under 100 cm if the timing belt is wide and steel reinforced as the one we use. You can cut everything with a timing belt machine as a rack machine can such as aluminum, wood and plastic. Racks are used for higher speeds and machines longer / wider than 100cm. If you require finer details, then timing belt is recommended. A rack machine is stronger and can take higher loads but does not have the same accuracy as timing belts. If you plan to cut wood, you won’t notice any difference between racks and timing belts.

What can i cut with a Raw 1.5
Soft wood, hardwood, particleboard, Mdf, plastic, aluminum, copper, 3D cutting, engraving and much more.

Is it difficult to build the machine?
If you’re something handy, it’s not difficult at all, follow the video instructions as well as the illustrations. The electronics can seem daunting but it’s very simple, look at our video and you’ll see what it takes to assemble the electronics.

Video instructions and illustrations

All steps are carefully documented with illustrations and video instructions. You will find all instructions on how to build the machine here: https://rawcnc.com/drawings-and-video-instructions-for-raw-1-5-cnc-diy-kit-100x100cm-with-timing-belts/

Is it difficult to operate the machine?
It’s always tricky to do something new but after cutting your first part you will understand how to do it. Once you know how to do it is very easy.

Below we list the different options. There is a lot to read and can look complicated but it’s easy. If you are confused or do not have the time to build a machine, we also sell assembled machines.

Different options (Click on the tabs)

• Waste table
• Type of electronics
• Electronic box
• Uppgraded Z-axel
• Spindle/router

A consumption or waste table is the table itself where you tighten the piece, and which is replaced occasionally if it is worn. We don’t include a waste table to this kit due to high shipping costs. You can easily cut your own waste table once your machine is buildt, look at the instructions over at the article section. We have clamps (to fasten the work piece to the table) as a separate product or make them yourself.

Valchromat is a more durable MDF that is translucent. If you treat Valchromat with oil, it will become waterproof and perfect as a table for a CNC machine that can get wet when you cut aluminum, for example. Valchromat is sold all over Europe and you should be able to find that. If not, you can use regular 12mm MDF

.

We use two types of electronics, a modern and a little older. The older driver version is better but requires an older computer with printer port. or a special USB adapter that converts the LPT signals to USB. (click on the link for more info). Read more below.

Arduino+CNC shield elektronics

Arduino with CNC shield is a simpler version of CNC electronics and can be used with any computer that has a USB port. These electronics has some limitations, such as handling multiple switches and zeroing plates found on our other machines. You can do well without these features if you only cut from time to time. Arduino cannot handle 2 switches at the same time, so it is not possible to calibrate the machine 90 degrees at startup, but it is easy to do it manually. It is usually this kind of electronics that comes with other DIY kits on the market.

CNC shield is not capable of having an advanced touch-off plate (Zeroing plate), so you have to start the machine from the surface of the material you cut, which is the way most people work anyway. Touch-off plate is a feature that is not needed, and you can do well without it. If you want a more advanced machine, look at Driver Electronics. You can also upgrade your electronics afterwards if you notice that you need a more advanced machine. Any upgrading requires upgrading of motors and other electronics.

Driver elektronics

Drivers with Breakout Board are the most professional electronics you can have for these types of machines. They are more expensive and require an older computer with printer port and 32Bit Windows operating system (if you run Mach3 software) or a special USB adapter that converts the LPT signals to USB. (click on the link for more info).

Some of the benefits of drivers are that the machine gets much stronger and has many more features like advanced touch-off plate (reset plate), calibration switches, on and off spindle, laser and plasma functions. The range of software is much larger and you can also use software that the industry uses.

If you choose Driver Electronics, you will be able to calibrate your machine so that it starts at 90-degree angle and you can also have an advanced touch off plate that we offer as a separate product or you can make your own. Read here what you need to run drivers electronics https://rawcnc.com/set-up-mach-3/

You can look at our website which drivers we use.

You can upgrade the electronics on your machine at any time. As soon as something new is on the market, just upgrade, your machine is compatible with all electronics designed for Nema 23 motors.

Driver elektronics with USB
There are not many adapters that can handle this and we only know one that works well, read more here

If you include electronics in your kit, we include a simple electronic box for the respective electronics. For Arduino, it means a bottom and a top with aluminum profiles as a frame. You can start with this box and then cut out a more advanced one if you want. The box is very simple so you get started and can move on from there.

.

Drivers
Has a more advanced box with the possibility of having DIN connectors and power switch. We do not include DIN contacts and power switches in the basic package, but they can be purchased if you want it. You can do well without this and is only an option for anyone who wants it. The only thing to keep in mind is to be careful and if you happen to break anything you have to buy new parts. We have no warranty on electrical components as it is beyond our control of how it is mounted.

Choose between trapezoidal screw and ball screw. Ball screw makes your Z axis stronger and has a softer movement. The screw is changed from the trapezoidal screw to a 16 mm ball screw with nut and housing. The block bearings are more widely spaced in all directions to stabilize the unit. The new Z-axis unit is 4-5cm longer than the standard Z-axis. Choose trapezoidal screw if you cut at hobby level while ball screw is for you who cut more professionally.

Spindle or router is sold as a separate product. You can have a regular edge cutter from Dewalt, Makita or Bosch or a better spindle with inverter. We recomend spindles, they are more precise and extreamly quiet.

Software for Arduino
You can download a demo version of Estlcam which is a very easy program to learn. With Estlcam you can cut in both 2D and 3D and the price of the software is very cheap compared to other software. You can use any software you want that supports Arduino and GRBL. Read more at www.estlcam.com. Read more on this page: https://rawcnc.com/how-to-cut-with-good-results/

Software for Drivers
For drivers we use a software called Mach3, there is also a newer version, Mach4, but the 3rd is sufficient. To set up your files, you can use Estlcam as mentioned above or a more professional program such as Vcarve. Read more on this page: https://rawcnc.com/set-up-mach-3/

Precision
Precision is a balance between the user and machine. It’s about how well your drawings are, spindle quality, spindle speed and how fast you cut. At normal speeds, the machine has a measured accuracy of about 0.2 mm. This machine is the result of many years of development. We have cut several thousand meters of material with machines like these and done it daily for many years. An aluminum machine cannot be compared to a 1-ton steel machine for 100000 Eur so do not have too high expectations. You should also not underestimate a machine like this. We have several large Swedish and foreign companies that cut with our machines in professional environments from cross country skis, hokey clubs, boats and car parts, speakers and aquarium manufacturing. We also have companies that have replaced their professional machines with ours since you can buy 50 machines like these at the price of one and if you only cut simple parts in wood, this machine is at least as good.

Who buys our machines and kits?
We have customers from all over the world from Asia to the United States and down to Africa. Those who buy our machines range from Hobbyists, companies, schools and institutions.
