Referencing
By default, axis referencing (homing) should take place before the 3D-group is formed from the PTP channel. Or it can be done from the NC program.
If axes are referenced in PTP mode, it can be done for several axes simultaneously. If axes are referenced from the NC program, it can only be done for one axis at a time.
