    Ladder is a pia to find the faulty switch. You have two switches, unclamp and clamp that face the z axis. The other 3 are a b and z. In the electrical print, it will show the switches and the x input bit to check them. I usually index the turret on those, and the second it starts to rotate, hit emergency stop. Then you should be able to manually rotate the turret and watch the inputs. Switches should have a label on the wire corresponding to the print. Replacements will be new 2 wire switches, and hope for the correct part number. Btdt.

    I ordered some switches I got some Omron TL-M2ME2 switches that seem to be a newer version of the original switches. They are obsolete as well, but there are still some new ones floating round ebay. I just got them today so hopefully I will get it working.

    I think all the switches are working right now. But the clamp switch (X1006.3) only works when the machine is reset. Once the switch looses signal it will not activate again. The wires go back to a board called A829168B in the cabinet, but I am unsure what that board does with the signals. If I reset the board by removing then replacing the plug the clamp switch works as well. I don't get why the ladder would not light up if the switch is getting a signal though.

    The new switches I ordered only supplied 6 volts instead of 24. I will have to add a pull-up resistor to make them work.

    I still don't get why it will index at some positions and not others. Everything should be the same for every tool post except position 1 which is not causing me any problems. As far as I can tell 2 switches B and D tell the machine which direction the turret is rotating. A counts the tool positions and tells the machine when the turret is aligned for clamping. Z is used to zero the machine at tool post 1. The final switch is used to tell if the machine clamped fully. I have been trying it again with the old switches but no luck so far. I think it may be a mechanical issue at this point.

    #1 mechanical issue is large center nut not tight enough. Must be tightened with the turret unclamped. Then really cranked down.

    The nut could be the problem. It looks like the turret will not move out far enough right now. When I tighten the nut it does not look like it will push the turret all the way onto the splines, it bottoms out first on that ring next to the splines. Is there a way to get it to come out farther, get that ring to go in more, or does the nut push that ring in as you tighten it?

    Thanks for the suggestions so far. I am definitely not the best at machine maintenance.

    I tried mounting the head again and I don't think the nut is going in far enough. I think the nut has to move in about 80 thou. Right now the lock screw is sitting about 10 thou farther out than the shaft. I think this might be why it is not fully clamping. When the machine clamps there is about 0.175 between the rotating turret head and the stationary part. Does anyone know what the distance should be when it is properly clamped down? I can't really get the nut any tighter either as the turret just rotates.
