Does it mean I should use G92 X0 Y0 Z0 to set zero instead of using 'Reset Zero' button on Universal Gcode Sender? How can I specific where to save the position in G54-G59?
I find that the button is running G10 P0 L20 X0 Y0 Z0
and the Return to Zero button is G90 G0 X0 Y0; G90 G0 Z0

Sorry for the newbie question

I’m using a cnc GRBL machine and Universal Gcode Sender.
I’m trying to save a default position to G54

I first place the spindle to a corner.
Then I run this to set the zero position:
G10 L20 P1 X0 Y0 Z0

Next, I move the spindle to a certain position and run this to return to the zero I set:
G54 X0 Y0 Z0
It works as my expectation.

However, when I press the Reset Zero button on the Universal Gcode Sender, the machine zero I set is reset.

Not sure if I have any misunderstanding to this.

Thanks in advance
