You should be using the latest Bugfix version. It is difficult to support old versions of the code.
You are moving the nozzle off the mesh. Set up things so the mesh is actually on the print bed and you are not moving the nozzle off the mesh.
With that said... I did put in a lot of code to handle the case where the nozzle moves off the mesh. It is possible you have found some corner case where a bad Z-Height correction value is being returned.
If that is the case... I do want to understand and fix that.
Right now, I'm gearing up to add more 'Off the mesh' Z-Height correction options. You really should be keeping the nozzle on the mesh. But I understand that puts a big burden on the user. And I understand it is possible to have a print that extends a little bit off the mesh and you didn't know that was going to happen. I'm going to add options to control how that is handled.
But right now.... Make your mesh big enough the nozzle doesn't leave the mesh.
