Is there anybody can help me solve a problem which confused me for a long time? my 3D printer can’t spit the material,it only spit out a little then never spit. I just can’t find out the problem. And the drill also even can’t touch the glass.(such a sad story) .Besides , when I upload a .STL file,it just didn’t automatically pop out the configuration of the translation from .STL to .Gcode. Where can I manage the configuration so that the file of .STL can be translate to .Gcode file ? thanks !
