Works perfect no G91 needed in any programing like thisThe single line move between parts will only work if the rest of the program is written in G91. He has it written in G90, so a single line move like that won't work without G54-G59 offsets.
To use G54-G59 you need to set zero for each one individually. Then when the next work offset is called it will use the defined zero for that one.
