Different step for axis

Good evening.
Finished editing my delta printer I realized to have a diameter of a pulley smallest.
In firmaware not able to set a number of steps for different axis.

#define AXIS_STEPS_PER_MM ((float)(MICRO_STEPS * STEPS_PER_ROTATION) / PULLEY_CIRCUMFERENCE)
#define XAXIS_STEPS_PER_MM AXIS_STEPS_PER_MM
#define YAXIS_STEPS_PER_MM 107
#define ZAXIS_STEPS_PER_MM AXIS_STEPS_PER_MM

What part of code I have to change for a number of steps to diferent axis?

Thank you.
Excuse me for the English but use google translator.

    For delta printers all axis have the same resolution, so you can not set different values. This would make the math much more complicated and slow.

    Thank you.

    Some indication where modify the firmware as required from me?

    Or where can I find documentation on the development of the firmware?

    Thank you.

    Sources are on github. work092 is current branch. What you need to change is in motion.cpp the delta transformation routine if you want this to work. I guess you have to scale somehow 2 of the 3 axis relative axis results to compensate different steps per mm.

    Good morning.

    Which software is possible use for debug step by step ?
    It 'very difficult to debug with Arduino IDE.

    Thanks
