Kev It is difficult for people to know how to answer if they have to start looking back through your posts to find out what you have done before or even what machine you have.

So how about keeping all the posts in one place as that would make it easier to follow. You need to supply more info and the procedure you have used to zero the tool etc. Even a sample of the first 20 lines of the gcode might help.
