I am very interested in your progress. I am in your boat exactly: I have a working Bridgeport and want to have a 4th axis. (there is a few things I wanted to do before working on the 4th axis). For the 4th axis, I have a Troyke CNC rotary table that I bought on eBay for $149: http://igor.chudov.com/projects/Bridgeport-Series-II-Interact-2-CNC-Mill/24-Troyke-Rotary-Table-U12PNC/ So maybe in a couple of months or sooner, I will hook it up. The only minor complication with this table is that it uses a resolver instead of an encoder. I heard that most people who want a 4th axis, buy a manual rotary table and add a position controlled motor to it. So, the bottom line, please share what you find. i ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
