Hello, to all from Russia (St. Petersburg).

Some time I used Polargraph Sandy Noble, very inspiring, but I prefer Zarplotter or it is necessary to build a machine with rectangular axes according to the CNC principle.
I want to build Zarplotter …
I bought a table and firmware. ))
I have Arduino Mega 2560 R3 + Ramps1.4 + 4 stepper motor 17HS4401 + 2004 LCD Smart Controller with memory card
Problem in compiling the firmware!
in configure.h
I replaced in rows
33
#define MACHINE_STYLE ZARPLOTTER
57
#define MOTHERBOARD BOARD_RAMPS
79-86
#define MICROSTEPS (16.0) // change this. microstepping on this microcontroller
#define DEGREES_PER_STEP (1.8) // change this. as advertised by the stepper motor maker

#define NORMAL_MOTOR_STEPS (200.0 / DEGREES_PER_STEP) // 360 / 0.9 = 400. 360 / 1.8 = 200.
#define STEPS_PER_TURN (NORMAL_MOTOR_STEPS * MICROSTEPS) // default number of steps per turn * microsteps
#define PULLEY_PITCH (2 * 20.0) // 2mm per tooth, 20 teeth.
#define THREAD_PER_STEP (PULLEY_PITCH / STEPS_PER_TURN)
#define MICROSTEP_PER_DEGREE (STEPS_PER_TURN / 360.0)

I get a compilation error:

What am I doing wrong or what have I not done !?
