Config_Reference.md - QGL change

[JamesH1978]

It has been mentioned that the offsets have no bearing on the points probed in quad gantry level, cited by user bjkroll on discord, both on beacon using its module and using the standard probe module with tap. For maximum accuracy, ensure your probe offsets are configured. seems to be extraneous and misleading.

Thanks James

FYI, the probe offsets are used in the calculations for z_tilt and quad_gantry_level. So, it is important that the user specify these values correctly.

We can certainly change the documentation if it is confusing though.

So the offsets are used to track back the nozzle position from the set points, which are manual absolute position for the probe over the point to give the actual nozzle absolute position for calcs? I think that makes sense... If so, then yes it may want to clarify rather than remove completely

Thanks James

Right - the probe offsets are used when calculating the toolhead position relative to the configured gantry positions.

Good to know the calculations are still good. Would it be clearer in the documentation to note these probe points as the nozzle position, and not the probe itself?
