Are you displaying commanded or actual position? ie, is the axis not where LinuxCNC commands it to be, or is LinuxCNC not commanding the numbers from your G76 command? The G76 code is here: https://github.com/LinuxCNC/linuxcnc/blob/9e4641a816ab8fe4f6a09a48fac550cc8aef1dee/src/emc/rs274ngc/interp_convert.cc#L4590 That seems quite explicit: double end_depth = fabs(k_number) + fabs(i_number); And the last moves are cut at start_x - end_depth -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
