So the X home offset becomes -10. G1 X10 M428

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.
