Description
Cartesio is a 3 axis printed Carthesian CNC machine, with a working space of 300x200x100mm(X,Y,Z).
The machine is designed to hold multiple tools at its toolhead.
This way one could connect a mill and/or a 3Dprint extruder and/or....
The axis are powered by 3 NEMA23 steppers, which are about the smallest in the lineup.
The max feedrates, with these small motors, are for X and Y 2400mm/min, and for Z 660mm-min.
Which are reasonable speeds for 3D printing.
When milling the block of wood (below on this page) I set the feedrate to 100, and the depth of the layer to 0.6mm.
Travel speeds were 2400 and 660.
This gave nice results.
Total amount of money spent for this machine: €750,-
Rather then having one long (endless) page here, I divided the assembly instructions in to separate pages in the wiki. Please follow the links

It is not exactly "Hello world" but it`s still the first milling experience for Cartesio.
The G-code was made with Skeinforge41. I`m still tweaking.
Cartesio uses 3 Hall-Θ endstop sensors
Cartesio uses a CNC arduino shield that can connect to a uno or a Mega.
It is still in prototype state, but information can be found here [2]

I will add the files at the appropriate pages of the assembly instructions.
Parts List
I will add the parts at the appropriate pages of the assembly instructions.
What we will be using now is :
Qnty | device | RS stockNr | |
1 | strut profile 20x40mm | 466-7219 | |
2 | strut profile 20x20mm | 223-666 |
Assembly Instructions
Assembling the Cartesio is a relative easy process.
There are however a couple of things that have to be done in a certain sequence, otherwise you will be (dis)assembling again and again.
Let's start by cutting the aluminum strutted profiles to length.
The Bosch/Rexroth profiles are used, because their profiles can accommodate the head of a button head cap M6 screw, and they are cheap.
These profiles are generally shipped in lengths of 3m, and the machine is designed in such a way, that almost all of the material is used.
Cut them like this :
20x40 profile is cut to 1x 256mm 6x 260mm 2x 570mm
20x20 profile is cut to 3x 90mm 3x 200mm 1x 260mm 2x 280mm 1x 296mm 2x 360mm
20x20 profile is cut to 1x 200mm 1x 296mm 2x 340mm 4x 440mm
Now we will begin our journey at the Cartesio Base.
After that we will go to the Cartesio Z-axis.
Then straight to the Cartesio X-axis.
And finish at the Cartesio Y-axis
Setup
So now that you have setup the individual base and axis, now it is time to connect them all together.
