Thanks,
Have you homed A? issuing G53 X0Y0Z0A0 would give an error - is this a typo? What version of EMC2 are you running? The CD version doesn't tell us this since you can run any version on it depending on what updates you have installed. You can always find the EMC2 version number in Help/About. ------------------------------------------------------------------------- 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 [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
