after have finished to mount my 3DP-12 and maked first test print (test cube) it seemed to be all done very good... but after some day passed to playing with some slicing software, the problem started to appear..... i don't know what parameter i have changed on printer or on software but the result now is terrible... i also tryed to reset to "factory failsafe" from lcd menu, and to generate gcode file from fresh installation of cura.. but result is the same.... searching for the problem i think it is related to bad filament's extrusion (too material extruded or some other).. attached a photo of first printing result (green cube) and last printing result (white cube)...
i have checked mechanical allignment, x, y, z, belt pull, pulleys, mechanically i don't find anything strange... this defect is showed alse in the internal part....
tips?
thank you very mutch
