TT-4 on lathe how to start

[OptionSR]

Good morning,
thanks for the document,
I tried this way but I already have numbers and it looks like it's calculating the difference, on your photo you can see not set, how do we put not set back on, because for me he keeps the last piece.
so my question how to change to not set?
thanks again and sorry for my english.

There is never a need to change the Z Reference or X Reference ("X Diam") to "not set".

You just set them where you need them, when you need them. The rest of the time they do not matter.

Good afternoon,

When you're saying your controller is calculating the difference, is it the difference between your current Z offsets and your new reference tool Z offset?

If this is the case, then what I suggest doing is to remeasure the Z offset for every tool you have while the TT-4 is in your spindle.

Can you include screenshots of your Tool Offset screen as well?

Thanks, in advance.

yes for the question and x ref too, when my first tools touch the TT in x it's suppose the diameter size of the TT so 18.965 mm ?
screenshots later i'm at work.
thank you
