Need Help!- Bridgeport 760 t16 vmc-tool arm time out

[jke6113]

I have a problem with a bridgeport 760 t16 vmc with a dx 32 control. I'm unable to run the machine due to a tool arm time out. A little history about the machine. the hard drive quit working about 6 months ago up to that point there were few problems with the machine. I purchased a replacement from emi and installed it. that is when I found out that i had two problems. the first was a x axis encoder problem that I had to get replaced, and the second is (tool arm timeout) . I have been unable to locate the cause of this alarm. I can home xyz axis with a g28 in mdi. but cannot home tool changer. I replaced the tlauf board in the back of the machine ,and I still have the same problem. running out of time to get this machine fixed it has been far to long since it has ran.

thank you

Most 760 machines had a motor to move the tool carousel to and from the spindle. The early 760-16 used a air cylinder. Make sure your software from EMI is that for the air driven toll arm in/out.
Assuming it is, then is the solenoid good?
Lastly if you have to run the machine, you could change the parameter for Number of tools to zero and this disables the tool changer. Then the machine will stop at a M06 and you change tools by hand.
