I just got my new toy used(2015 Mill/Turn) and the guy gave me what he had in regards to Mach 3 Mill, Mach 3 turn, and very light on the Shopmaster literature, said there was a lot of research that could be done online, cant find a whole lot. Anyways, have it running, learning what I can, noticed there is an open axis plug in on the Gecko 540, did a little research, looks like eiter a CNC tool post or rotary table, for what Im thinking for me would best be used with a rotary table, got on Shopmasters website, and they dont sell them anymore, but give them with the system. Found a no name one on Ebay, that can be sent with the 540 recepticle, that should be all I need right, then obviously going in and activating some items in Mach 3. Those of you guys that have the cnc rotary, is it something you use very much? thanks in advance, Mark
