I have an old Interact 412 with a Heidenhein 351 controller. I am looking for a 6 in. rotary table. Preferably tilting that I can use on my 3 axis machine. When I had 3 axis machnes before I was able to unplug the X axis and plug in a rotary table, played with some numbers and had 2 linerar and 1 raotary axis. I would llike to do the same thing now with this one. Any help on this will be great or who to contact. I would like to find a 4th driver for this machine also. All the wiring is there and the controller is ready. Just need the module to plug into this slot. I have other questions for now but this is a good start. Mike.
