+ | ==== Tests ==== | ||
+ | The first print was perfect. All consequent prints were bad. For the first layer, the nozzle moves too fast, tearing the printed line, and dragging it over the build plate. This is what under-extrusion looks like with Plasticine. Even after selecting a default profile this happens. There' | ||

+ | Future tests | ||
+ | * Do a visual test (video recording?) with lines on paper to see if the printer really moves 8mm/s. I have a feeling the printer moves faster than the first successful print. | ||
