AXIS : toolchange : extens take tool station position into account

Hello,

We use LinuxCNC to retrofit a PCB Router "Klingelnberg Micronic".
We just updated to version 2.7.8

The tool magazin is mounted to the x axis, the tool changer and measure station
are mounted within the table, moving in y.

This results in absolut machine coordinates that are handled in our toolchanger code.

This all works fine with one minor issue.

The extens take the tool change position into account, because the tool change program
is a sub program:


is there a way to avoid this ?

Thanks, Rainer.
