Beacon probe Z-offset is consistently too far from build plate

that's relative to T0 and is found via a button. If you have problems with that it's mechanical (ie loose nozzle / hotend etc)

But T1 offset has nothing to do with beacon.

Yes, you need to run SAVE_Z_OFFSET after you've finetuned for the first layer as it's dependent on nozzle temperature.

There are huge variations caused by mechanical changes btw, don't trust your measurements unless you've isolated all of the 5+ factors involved here.

All of this is changing in the next release btw, because people keep being confused (for good reason).

As in, it doesn't do anything. The model offset is for proximity scans not contact.

That said, model offset is absolutely useless if you use true zero.

You're confusing multiple thing. There's a few layers on top of the beacon code in RatOS. You need to use SAVE_Z_OFFSET, since RatOS adds nozzle expansion compensation on top. Klipper has no way to specify multiple offsets, it's all done with a single runtime variable, and thus if you want to save the z offset to the model, RatOS has to subtract the nozzle expansion compensation layer first or it would accumulate as your z offset over time. Follow the RatOS documentation.
