Hal confusion

Did you check all the HAL files?
iocontrol.0.user-enable-out could be connected in another HAL file- it is connected in the main HAL file if the config was generated with stepconf for instance.

The other possibility is you are not running the config/files that you think you are.I have had two versions of a config and edited the wrong one sometimes.

Yes 2 occurrences of iocontrol.0.user-enable-out:
49 net enable iocontrol.0.user-enable-out iocontrol.0.emc-enable-in
66 net estopactivated iocontrol.0.user-enable-out parport.2.pin-03-out

Line 49 shows iocontrol.0.user-enable-out (an output) being connected to
iocontrol.0.emc-enable-in (an input)

Since iocontrol.0.user-enable-out is an output while can't it be connected as an input to the parallel port card?

It can, but you must use the same signal name

You have two different signals (enable and estopactivated) connected to the same hal output

Ok - got it fixed - can't have 2 different signal names on a pin!

Pin names can only ever be used once (in, out... doesn't matter)

You get around this with signals. Signals names can be used repeatedly as often as you like on different lines and different hal files, but each signal name can only ever be connected to one output pin, but as many input pins as you like.
