Help with Macros (On_Abort.ngc

Based on the docs here , I have the following:

on_abort.ngc is in my config folder /macros
This is in my INI:
Basically I want to retract Z on abort.

What I get is on_abort attempting to run continuously, interrupting the interface and unable to home because of errors thrown by continuously trying to run on_abort.ngc

Any ideas where I went wrong?

Did not test it but i think this: Should be this: Notice the slash before macros.

Nice catch. Now it no longer gives errors continuously. Instead it says, "File Not Open". The machine can be homed, it throws occasional "File Not Open" warnings, but doesn't execute the G28 command.

When I run a program and abort it, it says "EOF in file:/(pathtogcodefile)/gcode.ngc seeking o-word: o<on_abort> from line:453"

Thinking about it, all I really need is this.

ON_ABORT_COMMAND=G28 z0.0

Is that a valid usage?

When I try it, I get a "Bad Character '[' used" error.

A (rather unexpected) cause of that error is if both the subroutine file and the loaded G-code file have % as top and bottom.

If the subroutine file is %-delimited then try removing them.
