Welding 2 filament

Hello all!

I had an idea today. I was tired to scrap en of roll filament, just because the remaining length was too short.
I tried to weld it by hand by heating it, but it did not work.
At work, I asked a friend to mill a small block of brass, cut it in half and then, to drill a 3 mm hole just in the middle.
I have to find a way to clamp the 2 parts together, insert a heatblock coming from a extra hotend I have, and a temp sensor.

Here the picture of the first part ;-)!

 

This technic could be use to prevent from scrapping filament, and also to combine colors!

See you soon

Full Graphic RepRap on the K8200 / 3Drag original controler

Hello!

I will make a small article to know how to implement a Full Graphic controler from RepRap discount on the Velleman K8200 3D printer (or 3Drag) original controler.

The full Graphic contoler look like this:



Cool eh? That would be better than the small LCD contoler.


It cost arround 10-30 euros.

I found on different website the wiring diagram of the full Graphic contoler

The pining have been done using shunts used most of the time for Arduino projects :


I needed to modify the Marlin firmware by replacing the following lines:

// The RepRapDiscount FULL GRAPHIC Smart Controller (quadratic white PCB)
// http://reprap.org/wiki/RepRapDiscount_Full_Graphic_Smart_Controller
//
// ==> REMEMBER TO INSTALL U8glib to your ARDUINO library folder: http://code.google.com/p/u8glib/wiki/u8glib
//#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

Do not forget to update your Arduino library by:
- Download the library here
- Unzip the file
- Drag and drop the unzipped file  into your document folder/Arduino/Libraries (normaly it's the original path)
That's all !


Upload the firmware, reboot and everything should work!

 

The usage of jumper cable is just temporary, the time that I do something cleaner.

In the background of the second picture, I will replace the small screen on my control board by the full display LCC.
