simple setup - do i need to use offsets?
1/ move machine to where I want the zero position and save it as 'machine zero position' ('home' button in emc I guess??)
2/ move machine to the corner of my workpiece and save this as' workpiece zero'.(' touch off' button ??)
TIA

position at zero/home or whatever you want to call it. then
save the position of the work/first cut point
I'm trying to do what it says here:
www.cnccookbook.com/MTCNCTipsTechniques.htm
which is what I have done in the past.
thanks

Just need a simple tool change
position at zero/home or whatever you want to call it. then
save the position of the work/first cut point
The machine zero (G53) which is used by G30 and G28 (and in which a tool change position would be defined) is relative to the home switch positions, and defined by the INI file.
If you don't have offsets, then I think that the home button will define the G53 for each axis such that the current position is the value from the INI file for Home.
And Yes, to zero the DRO and G-code XYZ you would use Touch-off into the G54 or other coordinate system. You can also use Touch-off to set your tool lengths.

Then move your machine to the work position and touch off each axis, this will set your DRO to x=0 y=o z=0.
You can now run your program from there.
To return to your "Home" position use G53
Such as
G53 G0 Z0
G53 G0 X0Y0
