What is your spindle encoder hooked to? Jon E and I saw this behavior on some PPMC boards but it is long fixed as far as I know. If you can capture the encoder count and index-enable on halscope when this happens, it would "tell all". Are you using G76? Like John K asked, are you using M3 or M4? ------------------------------------------------------------------------- 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
