Has anyone out there converted there knee feed on a bridgeport interact 1 mk2 to a fourth axis my control is heidenhain 2500 and has provisions for 4th axis.I know this is usually reserved for a rotary axis but i have to ask the question as i need extra travel and dont have enough in z axis.I wasnt planning on converting to ball screws at present as the accuracy is not extremely important.Thanks for any help greg b

No, but I have installed an Align Power Feed on the knee of my Interact 1 and it is a godsend - or maybe I'm just getting too old <g>

no real reason you couldn't. The control, however, would have no idea what you are doing. YOu could utilize datum shifts to deal with it, and if you always take up the backlash, it should work ok
