The feedback in this case is the number of steps that the FPGA reports having made (actually the distance it thinks it has moved, as the command and feedback are both in distance). For an open-loop stepper the P term of the PID should be exactly 1000. I think if you set P to 1000 it will start working. -- 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
