The point is that you have to reverse the drive rather than disengage the nut, wind back the carriage, re-engage the nut on the thread-counter and do the next pass. You can't disengage the nut during a mutli-pass threading operation when using the non-native thread pitch. (Actually, I believe that it is just about possible if you wind back to a stop and do something else clever that I once read about). I wonder if there is scope for a microprocessor thread dial, that lights an LED when the opportune moment to engage the nut arrives? -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
