Ok, so correct me if I am wrong (again) ..

 

Machine Home is set when I power the CNC on, to the current XYZA positions ? ..

This is seperate from where I set the XYZA Zero position when setting up for a job.

 

G28 command, refered to Machine Home and Not the Zero I set ..

 

G28 will move to Machine Home, then proceed to the starting position set in the milling code ..

 

So as long as my Machine Home is set away/above the stock, it will not cause crashes into the material when G28 is called ?

 


This is correct and a lot safer than using a relative offset above the stock. If you have tool changes (change from a short tool to long) you can make sure the longest tool clears using G28 where you could have problems using part offsets.
