Please see attached pictures. There are 5 limit switches that I found on the tool changer and the tool lock unlock.After I actuated all the switches I can now jog the Z axis after homing and pushing the reset on control panel. I got the tool changer to move one time. The change arm swung to the tool load or unload position and that was the last I could do.I forgot to tell you that the CRT has always displayed an error that I think must have been the last program running when it quit the prev. owner. I can't figure out how to clear it. It says error .08073 N000000. I did clear all the g code in the program and then used it to enter the moves for XYZ. It will run the XY moves in rapid, but still ignores a Z programmed move.The spindle at some point starts to do what I think is a tool change positioning? It rotates very slowly about a 1/4 turn - pauses for about 3 seconds and rotates again. Does not seem to be affected by the position of the Z axis once it starts. If anuone has a wiring diagram for a Burgmaster VTC 150 I would love to purchase a copy.
Thanks again for your help guys.

Try to do an M19. Orient the spindle to see what happens. See if it stops without any alarm and at the same spot.
