Hello everybody my name is Natan and I'm having troubles with my UM2. Since I bought it I can't have clean prints without the stringin. I try printing in low temperatures and high speeds but I can't solve it. Every time that I put more than 1 model it stringing everywhere. I can see that the material is been extruded when the hotend is traveling without printing. I show you a pic. Please if anyone has the same problem and you solve it or any help will be welcome!! Thanks!!
