M92 - Set Axis Steps-per-unit

Description

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 be in steps/mm unless inch mode is set with G20 (which requires INCH_MODE_SUPPORT).

Notes

Get the current steps-per-unit settings with M503.

With EEPROM_SETTINGS enabled:

  • This setting for all axes is saved with M500 and loaded with M501.
  • M502 resets steps-per-unit for all axes to the values from DEFAULT_AXIS_STEPS_PER_UNIT.
