The selfdrawing painting!
Never get bored by your current painting! any time, any place and any color as you wish. you can let it paint whatever you want! This machine had loads, loads of prototypes. Mine is controlled by an arduino UNO with CNC shield and GRBL controller, but you can use anything that you want that reads G-codes of NC-files. For making the G-code or NC-file you can use your normal 3D slicer or (what I prefer) Inkskape with the laserengraver extension.
Bill of extra materials; (apart of the printed parts)
-sheet of wood 375x600mm
-a steel plate(or glass,whatever you prefer)
-2x 8mm smooth rod 595mm long
-2x 8mm smooth rod 350mm long
-2x M8 treated rod 420mm long
-2x nema 17 stepper motor
-2x 608zz (skate) bearing
-1x 624zz bearing
-4x LM8UU linear bearing
-around 2meter of timing belt
-2 pulleys (for on the stepper motors)
-15x M3x16 bolt
-4x M8 nut
-some whasers to make sure that the belt won't dislocate
THE SELFDRAWING PAINTING
Ever had a wall that bored you? Do you have some technical skills that you want to test?
There is a DIY solution for you!
You are going to make an painting that writes on itself.It is based on a 3D printer/CNC milling machine. But instead it does not make anything, it draws something!
The whole frame is already designed for you, it is up to you to finish the last bit!
The assembly only takes about one hour and you only have to use some basic tools like allan-keys, some wrenches and a cutter.
This is going to be the result.
Step one is probably the hardest one. Getting all the parts.
Most of the parts can be printed with a basic printer (120x120mm)
the rest can be bought at your hardware store.
There is only one exception; The lazercutted plate. Not everyone has the luxury to have one at their disposal.
The assembly is quite straight forward, you can see an exploded view of all the parts on the picture below.
I recommend to clamp the lasercutted wood with the printed parts, the smooth rods and the treated rod first.
once you assembled the outer-frame, continue by building the x/y component bij mounting the two NEMA 17 stepper motors.
afterwards, place the pulley's,smooth rods, bearings and bolts. Tighten the bolts and secure the linear bearings if needed.

As almost every Reprap 3D printer, there is no tutorial how to do the electronics. This is because everyone as another way of doing it. There are many, many ways of doing it.
The challenge is up to you to find the easiest way to control it.
