Lead time 1-3 weeks
If you are new to building CNC machines you can read the article “Read before you build” There is a lot of options and different variations of the machine.
Raw EXTENDED is the most rigid version and can be up to 1800mm long and 1300mm wide. We don’t recommend building it larger. We have seen machines up to 2000mm in length and they work fine if you cut wood and other soft materials and it’s up to you to decide if you want to build it larger than the recommended size.
This product is perfect for anyone who wants the machine in other dimensions than the standard 1300x1800mm. The machine will also be cheaper if you buy the products yourself.
This is how it works, fill in your desired dimensions in the form below, and we will calculate the dimensions of the parts you need to purchase in addition to this package. When you have purchased the parts and this product, you have everything you need to build a Raw 1.5 machine in whatever measure you want.
NOTE, Use MM not CM for example 990 For a 990mm machine
Note that the plates are not painted. We have treated the plates in a drum so you can paint them directly. You may need to grind the edges a bit as they are laser cut which gives a slightly coarser edge. If you don’t want to paint them, you can just brush them.
The package includes over 500 pieces! All screws are labeled and in separate bags.

You can choose to include driver electronics and we will include everything you need from drivers to all cables, cable chain and screws. If you want Arduino or other electronics you need to buy that elsewhere.
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 driver electronics http://rawcnc.com/set-up-mach-3/
You can look at our website which drivers we use.

There are not many adapters that can handle this and we only know one that works well, read more here
We only use 1 Power supply of 14.5A. Each motor is 3A so together it will be 12A.This is at the limit of what is recommended.We have always used only 1 power supply which is sufficient for a standard Raw machine as we do not run the motors at full speed.If you are running the machine hard and at high speed, then it may be a good idea to split your motors into 2 power supply units. We have never needed 2 for one machine but if this is something you think is needed then buy one more.
We don’t sell spindles or routers due to warranties difficulties. There is a lot of good sources for this.
Go to www.ebay.co.uk for example and search for Katsu trimmer for a budget version or 1.5kw air cooled spindle with inverter for a more professional version. If you buy a spindle with inverter, then you can follow our guide in the article section on how to wire it. remember that a trimmer has a lot of noise and vibrates more while a spindle is very quiet and vibrates less. The spindle we recommend above has ER11 Collets which means that you can have 1-7mm endmills. A trimmer has usually 6 or 8mm collets. We have special adapters in our shop so that you can use 3 and 4 mm end mills as well. We will include a universal spindle mount with the hardware that fits most of the spindles and routers. You can also have an edge trimmer from Makita, Bosch or Dewalt, as long as the trimmer has a round shaft.
You need to thread your profiles with a m5 tap. We thread the plates for you. Choose a tap of good quality otherwise it can go off.
Note that if you plan to build the machine longer or wider, add more cable. We include cable for a large machine 180x130cm
What can I cut with a Raw 1.5
Soft wood, hardwood, chipboard, Mdf, plastic, aluminum, sketching, 3D cutting and engraving, etc. Note that aluminum is hard to learn to cut and there are better machines for it such as laser or water jet. If you only going to cut aluminum then look for a more expensive machine, like water or laser machines. If you want to cut a lot of aluminum, then you should look at more expensive industrial machines. We ourselves have cut 1000’s of meter aluminum with the machines but it is difficult to learn. The machine is mostly for hardwood, wood and softer materials such as plastic. Do not buy the machine if you only need to cut aluminum.
With rack you can cut at high speeds with very good accuracy. Racks gives a mechanical noise when you operate the machine, this is normal since you can’t lubricate racks in a dusty environment. The sound disappears after a while when the rack adjusts to the gears and it does not affect cutting results at any point.
