Threading without a thread dial. https://www.youtube.com/watch?v=FNajMA4I20A Make three marks, one on the spindle, one on the leadscrew, one on the bed. As long as you leave the leadscrew engaged you can open the half nuts to run the carriage back for each pass. The same should work with ELS or CNC if you have the control system able to return the spindle and leadscrew to the same place at the start of each pass. ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
