John, I think I got it, at least it is working much better now. I was trying to adjust FERROR, and when that did not work, thought DEADBAND or something like that might apply. What I did not adjust was MIN_FERROR, which the doc says applies only for very slow speeds. I was not having a problem at very slow speeds, only when I tried to speed up. But increasing MIN_FERROR now has it basically working (my accel and max velocity are still set low so I still have a little tuning to do).
I guess MIN_FERROR doesn't do quite what I thought it did. Regards, Eric Following errors happen when the position feedback fails to track the command within a tolerance. That tolerance is specified in your ini file - what values do you have? Seb has acknowledged that there are issues and is working on it. Further speculation, especially without hard data, is pointless. If you are curious about what is going on, break out halscope and take a look. The command, the feedback, the error, and the error limits are all available as HAL pins or parameters, and there is also a "faulted" parameter that can be used to trigger the scope. ------------------------------------------------------------------------- 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
