I finally set up the 4th axis and tapping head today. I tried to tap a 1/2NC thread in to some plastic.
I have tried to a few different things, and all it seems to do is pull out the tap out of the collet. I doesn't even show any signs of reversing spindle when retracting.
Here is the code I am using, just one hole. Its a little butchered up because I have changed it a few times.
m00t5m6(27/64 t drill)
Am I missing something very obvious, I have tried several different methods for retraction. The large head has a reverse ratio of 1:1.75, with .160" until clutch engagement.
I have only rigid tapped or used tension compression holders on a CNC in the past. On a drill press self reversing tapping heads work great, I am a little bit baffled with the situation.
Could some one post a tapping cycle of there own to look at.
