Tool touch off after tool change

[andrewbishop66]

Hi all I have a knee mill with the quill driven in cnc at the moment I use tool height compensation in the tool tables
I want to change to atomic tool compensation after tool Change as quill only has 150 mm or so of movement
Can I set the height difference between work top (z0) and my tool height setter manually and then automatically measure the new tool and apply the offset initial look at the version I’ve updated to would suggest it would are there any known problems
Thanks Andrew
