Dubot200(Bowden type dual nozzle 3D printer for hot weather and fast printing)

Hi. My name is Hyeon Jeon from imergine in Korea.
Firstly, I want to apologize if this posting is not appropriate on a regulation of this board or hurt your feeling.
(If then, I hope this posting can be erased by the board manager.)

Recently, I developed a DIY 3D printer which can be used effectively in hot weather,
and crowdfunding is now underway on the Indiegogo.
If you are stressed from nozzle blocking, filament leakage and printing speed,
please consider supporting this project.

I am a bit shy because there is nothing special on the firmware.
Although it works well, please let me know if there is any problem or something need to be fixed.

Thank you very much.
