Dear all, Thank you for them help! I solved the problem. I use John Kasunich suggestion to check the encoders. It is really 8000 count/rev, I use it to calculate the INPUT_SCALE and using HALmeter and SANYO DENKI softeware to check the encoder pulse in same value.
Yet there are another problem, how can I find the P value in PID setting. I tried any value to set it but I dont know is it correct so I capture a picture, please help me to check it. http://myweb.polyu.edu.hk/~icwfchan/pid.png P = 25.000 I = 70.000 D = 0.015 FF1 = 0.091 ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
