I have recently completed building my Hictop 3d printer and have little to no idea how to fix a couple issues. First thing is that the filament continuously extrudes from the nozzle when it is heated up so I have to remove it before a print begins. This usually leads to a messy base for the printed object. Second and a much bigger problem is that whenever the object prints it goes in a diagonal pattern. I am trying to print a simple robot and it should print upwards. Any ideas on what i should be looking at? Like I said I am completely new to this
