Error setting TOOL_CHANGE_POSITION

On my Schaublin, I will get started using a manual QCTP holder. So I want the lathe to retract X to 180, have me change the tool, and then continue. I have Gmoccapy's tool change working fine, except for the move to the change location in X. When I add this to the INI:
[EMCIO]
TOOL_CHANGE _POSITION = 180

I get the error
estop.hal:4: Pin 'iocontrol.0.user-enable-out' does not exist

If I comment out that TOOL_CHANGE _POSITION line, LinuxCNC loads fine, and the HALSHOW shows that iocontrol.0.user-enable-out does exist.
Looks like IOcontrol gets built later in start up than that INI line is read. Any ideas how to address that?

Thanks Tommy.
I had followed the example in the docs, which listed 

TOOL_CHANGE_POSITION = 0 0 2 - Specifies the XYZ location to move to when performing a tool change if three digits are used. Specifies the XYZABC location when 6 digits are used. Specifies the XYZABCUVW location when 9 digits are used. Tool Changes can be combined. For example if you combine the quill up with change position you can move the Z first then the X and Y.

I'll try adding the X and report back.

I added the X, but that is not the issue. Same error as before.

How about just two values, if you only have two axes..

Sorry slow reply, I had a work trip this week.

I have tried adding a value for Z, but always the same error.

here is the docs:

TOOL_CHANGE_POSITION = 0 0 2 - Specifies the XYZ location to move to when performing a tool change if three digits are used. Specifies the XYZABC location when 6 digits are used. Specifies the XYZABCUVW location when 9 digits are used. Tool Changes can be combined. For example if you combine the quill up with change position you can move the Z first then the X and Y.
