I have just aquired a Bridgeport Series 1 machine with Anilam Crusader II 3-axis controller. The x and y axis work great. I can input programs manually into the controller and run them with no problems if I do it in SINGLE STEP mode everytime, but in AUTO it sometimes gets stuck on a step and I have to reset it and start again. My big problem is the Z-axis is not working at all. When I first started it up it let me jog the Z-axis one time and since then it does not move or attempt to move and just errors out and displays 18 in the feed display. I have checked the wiring connections on the Z but do not see any problems. Does anyone have any suggestions, servo or driver board and does anyone have parts that might fix the problem. Thanks
