I have considered adding spindle accel and decel now that spindles look more like axes and have their own INI sections. (and, also, spindle homing) One serious complication: Spindle-at-speed calculation. With the current system (and with spindle speed ramping handled in the VFD) it is easy to use a VFD output pin for at-speed. If the ramp is handles in LinuxCNC then the spindle is _always_ "at speed" even if it is not at the final target speed. -- 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
