I have a Bridgeport Interact II with the Heidenhain TNC 151 controller.
Batteries died and I lost all the parameters.
Lucky for me I have them all in a list and was able to enter them manually.
Everything is back to normal, the machine boots up fine but the spindle wont come on when I press the spindle enable button and twist the knob to turn on the spindle.
My best guess is that there is a parameter to look for an interlock switch on the (missing) guards for the table. I don't have any guards on my machine.

Is there a parameter that is set at either 0 or 1 to check for an interlock switch? I've been doing some web searches and found a list of parameters but nothing for a door lock.

Edit: I think I found my answer in this thread bridgeport with 151
Guess I should have searched first :-\
