It sounds to me like the enable signal assignments are made in a way
that creates them as three different calls to create the same signal.
The first invocation sticks but the next ones error out. In your .hal
file, try assigning the axes enable with something similar to:
~~~~~~~~~~~
+--make up a unique signal name
| +--Master, whatever you use for an enable input
| | +--Slaves, list of parport output pins
| | |
V V V
net AxesEnable axis.N.amp-enable-out parport.0.pin-04-out
parport.0.pin-05-out parport.0.pin-17-out
~~~~~~~~~~~
Then comment out the other net commands that used to create the axes
enable outputs.
Posting your .hal file might help too.
