Hi Ash
For some reason I can not open your file as it indicates it is an old version and will not let me view it!
From your previous interest in edge finders in other threads I asume this is similar.
The kick on edge finders is a nack that can only be learnt by observation and practice. I do not like them and use a DTI where ever possible comparing the reading from a refference which is part of the machine table. This reference is also a check on the home zero of the CNC which in my case is set with inductive switches as I got variable results with mechanical micro switches and optical ones are a no no with flood cooling.
In my opinion edge finders belong with manual machining and are the province of machinists with a lot of experience under their belts as well as formal trainning where the use of both DTIs and edge finders form part of the indexing of the job to a machines axis in one or more planes.
If you care to send me an uncompresed file I may be able to help further.
