M428 - Home Offsets Here

Description

Use M428 to set a persistent offset to the native home position and coordinate space by assigning the current position as the native home position. See the example below.

• The current position must be within 2cm from 0 or an endstop.
• The current position is set to the native home position.
• Any previous position shift from G92 is cleared.
• The home offset is persistent — added to the current position until changed.
• Some uses include fine adjustment of Z position (without moving endstops) and shifting the coordinate space to print on a different part of the bed.

Notes

• Only the Z offset can be altered on DELTA.
• This GCode can be disabled with NO_WORKSPACE_OFFSETS to optimize movement.
• Changing the home offsets will not invalidate bed leveling or other saved data.
• If EEPROM_SETTINGS is enabled, the home offsets are saved with M500, loaded with M501, and reset with M502.
• Use M206 to set the home offsets directly.
