G53 no fit error

[wupinstick]

I created a tool change script (see below) and it seems the G53 command causes a no fit error on the Z axis. the program still runs fine. Should I be going about this differently? My Z limit switch is set to max travel. So when I home the machine the axis are X0 Y0 and Z3.347.

EDIT: looks like this issue has already been documented here
