Obviously I'm not contemplating threading at 10K RPM! However, I'd like to leave the encoder installed at all times which is why I'm concerning about it surviving at high RPM. Suggestion for a cheap gear tooth sensor? _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
