I remember talking about this on IRC, but can't remember who with. It would be possible to ramp the spindle speed internally to LinuxCNC, but it would break nearly all the spindle-at-speed setups out there. (as the spindle would be permanently at commanded speed, but not at the final speed). One answer would be to add a spindle-speed-limited pin. I will bear this in mind if and when I get round to the plan of adding homing for spindles too. > and some other stuff to hijack the values but so far that hasn't worked and > LinuxCNC won't start. What's the error message? All that you posted looked OK, unless I am scanning over the same error as you are. -- 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 [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
