Thanks Hood,
Will modify and see what happens.

Threading works in the latest version of Mach and also SS plug in. To get good threads there should be no backlash in your
lathe. ( i know, i know.....get off my duff and fix the punny lathe already!) That is not going to be the case for a lot of users and they will need to have backlash compensation anad we know that may not give the desired result . The SS still dosn't provide for it as of today. So about only chance for the user to get a thread will be using G32 and having the Gcode produced will be desired. That leaves one with with few options:
1.Write the code
2.Have a program which generates it
3.Modify Brian's Wizard ( generates G76) output by changing "test=false" to  test=true in m1076.m1s as shown in previous post
   using the vscript editor.
4.Use papabears Quick Threading ( don't remember the code output, but, will refresh my memory)
5.Change the macro ( see 3 above )
May be others but that's what comes to mind.
