So if your limit is set 1mm above the table, the z-value you give it, shouldn't be lower than 1.001mm at the end of the probe move from where its at at the start. If the probe contact is not made by then, you get a different error.
I assume you have verified with a halmeter, watching motion.probe-input, that the probe circuit is working? > ---------------------------------------------------------------------- >-------- _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
