I think that "gearchange" was written for a Bridgeport, is that any better for you? http://linuxcnc.org/docs/2.8/html/man/man9/gearchange.9.html It might not handle the fwd-rev commands quite as you want, but it's a fairly simple HAL component and they are easy to modify. (Especially if you know C already, or are prepared to learn it) https://github.com/LinuxCNC/linuxcnc/blob/master/src/hal/components/gearchange.comp -- 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
