I do not use the home all function, it lets me watch to avoid any collisions when homing.
I don't know why your homing is so slow, I do the initial search at something like 45 IPM. Home is defined as a specific place, so machine limits can be known. (Not so important on a rotary axis.) The workpiece coordinates are some offset from that. If you move the home position, then the workpiece coords move, too. It sounds more like you want to set workpiece coords rather than homing.
