Error while compiling CNCRouterISR.cpp:136: error: ‘inf’ was not declared in this scope

[Tobias H.]

Hello,
first of all: thanks a lot for that software!
I wanted to install it via Arduino IDE 1.5.6-r2 but I am getting that error and don't know what to do:

/tmp/build6346497778242834630.tmp/CNCRouterISR.cpp: In constructor ‘CNC_Router_ISR::CNC_Router_ISR()’:
/tmp/build6346497778242834630.tmp/CNCRouterISR.cpp:136: error: ‘inf’ was not declared in this scope

I used the config-wizard, copied the new config.h into the folder where the .ino is and backup the original config.h
Thanks for helping me.
