I found probe offset is not applied for QGL sequence unlike to bed besh calibration. It seems “use\_xy\_offsets(True)” is precluded for QGL. I checked QGL can work with offset by adding “use\_xy\_offsets(True)”.

I think it would be necessary at least for safety. Without a consideration of probe offset, toolhead may try to probe at out of bulild plate, which can cause serious problem to the printer.  
But I also do know there wouldn’t be difference in terms of performance, so I would like to know is there any history to not applying xy\_offset for QGL.

```auto
#in quad_gantry_level.py 
self.probe_helper = probe.ProbePointsHelper(config, self.probe_finalize)

```

```auto
#in bed_mesh.py 
self.probe_helper = probe.ProbePointsHelper(
            config, self.probe_finalize, self._get_adjusted_points())
        self.probe_helper.minimum_points(3)
        self.probe_helper.use_xy_offsets(True)

```
