Cube test

thingiverse

Another test cube of your 3D printer. Made with freecad, I design this cube to test the edge outside and inside holes. Three faces have circles 2,3,4,5,12mm and three faces have octogon 15mm and hexagon 10mm. Results: Don't touch the number of steps per mm inside the firmware, but you need to adjust the size of your extruder, and you need to reduce the edge. First step, check the steps per mm of your extruder. Here, my extruder needs 96 steps/mm. No need to print anything. Second step, print one cube with normal parameters like steps per mm. My cube has 20.3mm and circle 11.7mm and some gaps on top. Third step, correct the size of your extruder to reduce the gaps on top. Fourth step, correct the edge size. Here I reduce 0.15mm each edge. Good luck.
