We see so many posts of failed first prints where the new printer owner starts with some really advanced models.Please, for your own sake, start by printing the boring Calibration Cube. Print it until the dimensions match and the layers look good.Then, move on to Marvin to continue tuning your printer.Last, print Benchies to tune cooling, bridging, and retraction.If you start with complicated models, frustration will set in very quickly.Like with every acquired skill, 3d printing takes time to learn. https://ift.tt/2xJgIdS
