4th axis and Extruders?

I have a tool wiper set up and previously ran it as the second extruder, but there is a need for a home switch on this mechanism. I noticed that smoothie could be set up to 6 axis here “smoothieware*org/6axis” and gave it a shot. After replacing the endstop section and adding the A axis the smoothieboard won’t post. If I comment out the extruder section or the A axis section, or leaving the A axis pins undefined the smoothieboard will post.

Am I left with either A and B axis or Extruders? How can I get home switch functionality for this tool wiper axis?

Thanks in advance!

We figured this out.

The config was crashing because we compiled 4 axis instead of 5 axis. Smoothie will crash if you try to define more axes than the firmware is compiled for (the extruder counts). After compiling 5 axis we were able to define both extruder and A axis. I can now home everything and use the extruder as well.
