Hello all,
I received the Ultimaker as a gift. Assembled it without problems - the wiki documentation was extremely clear, thanks! The printer printed excellently already without any calibration (and without me knowing anything about calibration too...). I just opened Cura, did the wizard, after which it sent me to that Ultimaker robot model and I just hit "print", that's it.
There's only one problem, not a very serious one, but still: it seems that before (when heating up) and after printing (when the head is still hot), filament comes out of the head without the extruder moving. As a consequence, often my prints have random filament blobs, consisting of filament that came out of the head while it was heating up, attached to them. Moreover, it seems that because of this filament loss during the heating and cooling phase, there's too little pressure when the actual print starts, such that the first line it tries to print is often very thin or nonexistant. Again, it's not a serious issue; it seems to usually solve itself during the print, and any random filament sticking out I can easily remove afterwards, but I'd still like to solve it if possible. Any advice?
