Hey guys I'm wondering if anyone here can help me. I have a 1990 Bridgeport Interact 308 VMC that im having some issues with. the first issue i had was the 24Vdc powersupply went bad. Ive fixed this problem but now the spindle will not orient itself for tool changes. when i run a tool change program the Z axis goes to the right height and then the spindle oscilattes back and forth.
this machine uses a Heidenhain tnc 2500 controller. any help here would be much appreciated
