If the driver still uses stepgen then I think you are doing it wrong... Look at how the Pico and Mesa drivers do stepgen and PWM, they read a steps-so-far number from the FPGA card, do some calculations, and tell the remote device how many steps to output in the next servo period. stepgen.c isn't involved at all. -- 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 _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
