When do you get that message?  The rest of your email makes me think it
happens on M6.

I use [EMCIO]TOOL_CHANGE_QUILL_UP (and TOOL_CHANGE_AT_G30), and i've
never gotten that error on a tool change.

It might help that my [AXIS_2]MAX_LIMIT is 0.000001, i see that the docs
for TOOL_CHANGE_QUILL_UP say "This is the same as issuing a G0 G53 Z0.".
 Maybe your Z max limit is 0 and you're running in to some weird
floating-point rounding error?

Are you using any of the other [EMCIO]TOOL_* options?

This is so that after an M6 you're always in a well-defined position.
It could be bad if your program performed different motions depending on
what tool was loaded when it started.
