Webb14 juli 2024 · Hermann–Mauguin notation is sneaky. It tells you the nature of a crystal's symmetry when viewed along certain axes, but not the precise realisations of those symmetries. It does not tell you the positions of rotation and screw axes in … WebbGlide planes and screw axes. Two of the symmetry operations involved in the space groups are not contained in the corresponding point group or Bravais lattice. These are the compound symmetry operations called the glide plane and the screw axis. A glide plane is a reflection in a plane, followed by a translation parallel with that plane.

Webbprojections onto a 2- or 3-fold screw axis, then that screw axis is removable. Thus, for example, because all rhombohedral and cubic Bravais classes have lattice vectors whose projections on the 3-fold axes are not lattice vectors, no space groups in these Bravais classes can have essential 3-fold screw axes, but all have removable 3-fold screw ... WebbRotation distance¶. Stepper motor drivers on Klipper require a rotation_distance parameter in each stepper config section.The rotation_distance is the amount of distance that the axis moves with one full revolution of the stepper motor. This document describes how one can configure this value.
