Just a heads up to the new people with 3d printing. After setting up my small 3d printer, every thing works. (it was night, very tired)After a while, i went to bed. (shutdown computer)Next day 3d printer wont connect to the computer. After a loot of anger, i found out it must be a bug. Start the repetier program, go to printer setting, connection, port: (it was on automatic) I had to choose manually, i tried port 4. then it connected again. Finaly...While printing my first 3d figures, i found out that it not that easy as it looks.In short terms, the printer have some issue to start bulding, the pla plastic wont stic, and it take a secund before it comes out of the nozzle. That will resoult in print failere, and if you start printing and walk away, i guess the printer will be "printed" with plastic.So, when you design something, design a plate under the design. Im not 100% sure it will work, because i'm printing my first print ever. (a serius one, not a dick, that was my really first one, totally failure)
