I realised last night that the coordinate system on my mill is incorrect when I run the horizontal spindle.
Curiously nearly every diagram that I can find online also seems to be incorrect. Or, at least, ambiguous. https://images.app.goo.gl/XuzUowMJyK3ffabD9 = Ambiguous https://images.app.goo.gl/iczsGEAgDueBfnCT9 = Left-handed And: https://images.app.goo.gl/dSkmwhBPRojMJXdx8 = Correct... It's taken me 10 years to notice, but I am going to have to reverse my X axis in horizontal mode. -- 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, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
