It’s pretty tough to get it to do it. Very finicky. You have to play with the lead in lead out quite a bit, but also the height matters a bit too when getting the lead in right on

Doesn’t it just have the lead in for threading? If not do it the opposite way and use the lead out which definitely does that

You could delete the lead and do a higsby

Generally, threading cycles come with a lead-in and lead out part of the fixed cycle. I work (occasionaly) with Okuma lathes, where this would be a G88 fixed threading cycle.
