hi everyone I made this 3d printer myself.(https://www.instructables.com/id/Cherry-60-3D-Printer/) I used the ender3/ender5 board (used) to make it work. Currently, I used nema17 motor on x and y axis and 28Byj-48 motor on z axis but, when printed (xyz 20mm cube), the printed one is much lower. However, the Stepps/mm has been modified to 4000 but still does not function as it is in the oby booboo4641 - Sanguino(lolu)
