Hal confusion

Booting into Axis, Failure Is:

Line 66 in 2X-BoxPinOutTest.hal is apparently causing a problem.
I cannot find where the name "estopactivated" is mentioned in any file being used, 1BP.ini, 1BPstepper.hal, or 2X-BoxPinOutTest.hal Files are attached.
What can be causing this error? (By the way - It used to work ok, but apparently something has gotten contaminated.)
Is there a better way to connect the hal pin "halui.estop.is-activated" to a parallel port pin?
jensor

the halui pin you use needs to be in a postgui file
you can use the motion pin
iocontrol.0.user-enable-out

You have a conflict in2X-BoxPinOutTest.hal:

net estopactivated halui.estop.is-activated parport.2.pin-03-out
...

net allhomed logic.0.and parport.2.pin-03-out

In line 66 of the file 2X-BoxPinOutTest.hal is the line then again in in line 126 you tried to connect the same parallel port pin
Any pin name can only be used once in all of your active hal files.

Replacing:
net estopactivated halui.estop.is-activated parport.2.pin-03-out
With:
net estopactivated iocontrol.0.user-enable-out parport.2.pin-03-out
Leads to error:

So this command isn't available before the postgui file

Postgui has nothing to do with it. It is the fact that you already used that pin name earlier on line 49.
