If you would like to try building your own here are some links, http://www.cnc-projects.de/ <- look at cnc-revolver http://www.cnczone.com/forums/showthread.php?t=46771 I ran across one other also that use pins to lock into position, But I don't remember the web site at the moment ----- Original Message ----- From: "Kirk Wallace" <[EMAIL PROTECTED]> To: "Enhanced Machine Controller (EMC)" <[email protected]> Sent: Friday, March 07, 2008 7:03 PM Subject: Re: [Emc-users] Powerdex Tool Changers
