Use M92 to set the steps-per-unit for one or more axes. This setting affects how many steps will be done for each unit of movement.

Units will usually be set in steps-per-millimeter unless:

• The firmware has INCH_MODE_SUPPORT enabled and has been set to Inches Mode by G20 or by having inches as the default unit.
• The machine is a SCARA in which case the A and B axes are configured in steps-per-degree, not steps-per-distance.
