Two billets have a smooth surface without surface defects, while the third one has a crack near one end. I tried googling this issue. Cold extrusion is, aside from sheet metal forming, the second most famous process in metal forming. It seems despite my best efforts the extruder pushes out filament that turns into a kind of road-block along the extruder path so blocking its movement and triggering the “echo too long extrusion prevented” message. Types of extrusion Cold extrusion Warm extrusion Hot extrusion Mechanical change of material owing to its slow movement under strong pressure and formation of the new set forms. It's like it just jumps into mid g-code and ignores homing or start code all together. Until now. In micro- and meso-forming processes, the.
