Stop/Start spindle during threading

I can pause a G76 cycle in the Axis GUI during the non-sychronised threading moves - can I also stop the spindle and jog away so I can measure the thread, then restart the spindle and have LCNC return to the correct thread start position and sync the threading pass correctly? I want to be able to check the thread during the cutting cycle.

One thing that might actually work is to put the spindle override to zero.
Let me know if it works.

Thanks for the suggestion - could you elaborate a little on 'spindle override' - is it a .ini file setting?

No, not in ini.
Check:

I don't understand the relevance of 'spindle overide' in relation to my question - apologies for my ignorance!

This is my point of view:
During the threading, the motion is synchronized with the spindle.
If the spindle is with override = 0, then no motion will occur and you can check the thread, if you place spindle override = 100, then it will continue to work.
It will not able you to jog during the work, but it allows to "pause" the work for checking.

Thank you - this makes sense. I don't have a spindle speed overide in AXIS, but I do have manual control over the spindle speed outside of LCNC - when I try dialing this to zero, the G76 cycle pauses, so I can make a measurement now
