Was never going to get into 3d printing cause i thought it was too complicated. But when i saw one on sale for $50 i had to pick it up! Finally got everything going and pretty surprised of how smooth the bottom section turned out. But the top, not so much. Does anyone know if i can stop stringing or why the top half has a couple gaps in it? Is it just cause its a lower end model and its not the best? (ender 3 v2) Please let me know!
