We have just received one of these and I started to build it today, it was given to our school by are sponsors. We currently have a small cube 3d printer which is very limited in the size of the items you can print. This printer is a deltic3d I do not really know much about it. But will you you know when I have finished, I have spent around 3.5 hours trying to ensure it is built right. Here are some picture of the build.
The fans on the effector, the part that holds the hotend, should be blowing toward the hotend to cool the print. You have them facing backwards. Good luck on the build 
@Kamil_Steglinski I will change them many thanks, I let some students put it together at that stage, and never checked it. I will change right away.
I am so happy you will not have to rely on the Cubify system’s proprietary print cartridges — total rip off.
