Trying to run this on a machine whose machine unit is inch. % g7g21 (disameter mode,g21mm mode) s500 (#<_tp_mm> = 1.00) #<_tpmm> = 1.00 ( a 1.0 mm thread ) #<_pitch> = [1.000 / #<_tpmm>] (debug,pitch=#<_pitch>) ( set threads OD ) #<_thread_OD> = 8.9500 ( Make smaller till fits 8mm.5 nut )
( from thread_OD set drive& retrace diameters ) ( set drive line OD ) #<_drive_line>=[#<_thread_OD> + 0.500] ( mm ) (debug,drive line=#<_drive_line>) ( set z far enough away sync is good for startup accel wibblies ) #<_zdrive_start>=46 (mm) ( move to here, goes to 18mm displayed in mm ) ( ending point of thread at first pass, Q will advance it! ) #<_zend> = 27 ( mm but didn't step it that far ) ( calculate this K from pitch ) ( set k, peak to valley of std USS/USF thread format = pitch/0.866 -10% clipped from peak and valley ) (#<kpp> should=1.0, debug print it) ( so I want to use 80% of pitch /0.866 according to the Handbook) #<_kpp>=[0.8 * [#<_pitch> / 0.866]] (debug, kpp=#<_kpp>) ( set threads OD, drive_line minus i ) #<_i_cut>=[0.000 - [#<_drive_line> + #<_thread_OD>] + 0.1] ( i_cut tbd after watching it cut air) (debug, i cut=#<_i_cut>) g1f60 x#<_drive_line> m3g4p2 (start spindle, wait for speed) g1f60 z#<_zdrive_start> g76 p#<_pitch> z#<_zend> i#<_i_cut> j0.010 k#<_kpp> r1.96 q30.3 h2 e0.25 l2 ( leave it where it started from ) g1f60 x#<_drive_line> (but out of the way for test fits) g1f60 z[#<_zdrive_start> + 4.00] g1f120x21.1 (back it out of the way to check screw fit) m5 m2 % Obviously I screwed up, or 2.5.4 can no longer do this. I would rather I screwed up. But its bothering me, a lot, that the G20-21 applies only to the length now, and there is no way to switch the radius/diamater from inch to mm.
