I have a Sabre 1000 machine that runs great and we bought it with a 4th axis attachment that we never triet untill now. I got the 4th axis all connected to the machine but I can't seem to get it to work. when I look in the cabinet on the 4th axis drive it only has one light on and seems its not enabled. Is there a way to enable the axis as it seems that the controll at one point was designet for this. I tried several commands to move the A axis and nothing seems to happen. Please help.
