// BASIC SETTINGS: select your board type, thermistor type, axis scaling, and endstop configuration

//// The following define selects which electronics board you have. Please choose the one that matches your setup
// MEGA/RAMPS up to 1.2  = 3,
// RAMPS 1.3 = 33
#define MOTHERBOARD 33 

//// Thermistor settings:
// 1 is 100k thermistor

//// Calibration variables
// X, Y, Z, E steps per unit - Metric Prusa Mendel
//float axis_steps_per_unit[] = {52.4934, 52.4934, 3200/1.25, 1487};  // original figs from MakerGear Rick
float axis_steps_per_unit[] = {52.4934, 52.4934, 3200/1.25, 1487 / 1.16};  // reduce e-steps per mm for extruder

//// Endstop Settings
#define ENDSTOPPULLUPS // Comment this out (using // at the start of the line) to disable the endstop pullup resistors
// The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins.
const bool ENDSTOPS_INVERTING = true; //set to true to invert the logic of the endstops
//If your axes are only moving in one direction, make sure the endstops are connected properly.
//If your axes move in one direction ONLY when the endstops are triggered, set ENDSTOPS_INVERTING to true here

// This determines the communication speed of the printer
#define BAUDRATE 250000

// Comment out (using // at the start of the line) to disable SD support:
//#define SDSUPPORT

//// ADVANCED SETTINGS - to tweak parameters

#include "thermistortables.h"

// For Inverting Stepper Enable Pins (Active Low) use 0, Non Inverting (Active High) use 1
#define X_ENABLE_ON 0
#define Y_ENABLE_ON 0
#define Z_ENABLE_ON 0
#define E_ENABLE_ON 0

// Disables axis when it's not being used.
const bool DISABLE_X = false;
const bool DISABLE_Y = false;
const bool DISABLE_Z = true;
const bool DISABLE_E = false;

// Inverting axis direction
const bool INVERT_X_DIR = true;
const bool INVERT_Y_DIR = true;
const bool INVERT_Z_DIR = true;
const bool INVERT_E_DIR = false;

// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1

const bool min_software_endstops = false; //If true, axis won't move to coordinates less than zero.
const bool max_software_endstops = true;  //If true, axis won't move to coordinates greater than the defined lengths below.
const int X_MAX_LENGTH = 180;
const int Y_MAX_LENGTH = 180;
const int Z_MAX_LENGTH = 110;

const int NUM_AXIS = 4; // The axis order in all axis related arrays is X, Y, Z, E
float max_feedrate[] = {200000, 200000, 240, 500000};
float homing_feedrate[] = {1500,1500,120};
bool axis_relative_modes[] = {false, false, false, false};

// Min step delay in microseconds. If you are experiencing missing steps, try to raise the delay microseconds, but be aware this
// If you enable this, make sure STEP_DELAY_RATIO is disabled.

// Step delay over interval ratio. If you are still experiencing missing steps, try to uncomment the following line, but be aware this
// If you enable this, make sure STEP_DELAY_MICROS is disabled. (except for Gen6: both need to be enabled.)
//#define STEP_DELAY_RATIO 0.25

// Comment this to disable ramp acceleration

//// Acceleration settings
// X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot.
float max_start_speed_units_per_second[] = {25.0,25.0,0.2,10.0};  //0.2  //10 for mosaic?
long max_acceleration_units_per_sq_second[] = {1000,1000,50,10000}; // X, Y, Z and E max acceleration in mm/s^2 for printing moves or retracts  //100 Z for mosaic
long max_travel_acceleration_units_per_sq_second[] = {500,500,50,500}; // X, Y, Z max acceleration in mm/s^2 for travel moves    //100 Z for mosaic

// Machine UUID
// This may be useful if you have multiple machines and wish to identify them by using the M115 command.
// By default we set it to zeros.
char uuid[] = "00000000-0000-0000-0000-000000000000";


//// PID settings:
// Uncomment the following line to enable PID support. This is untested and could be disastrous. Be careful.
//#define PIDTEMP
#ifdef PIDTEMP
#define PID_MAX 255 // limits current to nozzle
#define PID_PGAIN 180 //100 is 1.0
#define PID_IGAIN 2 //100 is 1.0
#define PID_DGAIN 100 //100 is 1.0

// How often should the heater check for new temp readings, in milliseconds
// Comment the following line to enable heat management during acceleration
  // Uncomment the following line to disable heat management during moves
// Uncomment the following line to disable heat management during travel moves (and extruder-only moves, eg: retracts), strongly recommended if you are missing steps mid print.
// Probably this should remain commented if are using PID.
// It also defines the max milliseconds interval after which a travel move is not considered so for the sake of this feature.

//// Temperature smoothing - only uncomment this if your temp readings are noisy (Gen6 without EvdZ's 5V hack)
//#define SMOOTHING
//#define SMOOTHFACTOR 16 //best to use a power of two here - determines how many values are averaged together by the smoothing algorithm

//// Experimental watchdog and minimal temp
// The watchdog waits for the watchperiod in milliseconds whenever an M104 or M109 increases the target temperature
// If the temperature has not increased at the end of that period, the target temperature is set to zero. It can be reset with another M104/M109
//#define WATCHPERIOD 5000 //5 seconds

//// The minimal temperature defines the temperature below which the heater will not be enabled
#define MINTEMP 5

//// Experimental max temp
// When temperature exceeds max temp, your heater will be switched off.
// This feature exists to protect your hotend from overheating accidentally, but *NOT* from thermistor short/failure!
// You should use MINTEMP for thermistor short/failure protection.
#define MAXTEMP 245

// Select one of these only to define how the nozzle temp is read.

// Select one of these only to define how the bed temp is read.

    I’m getting the following error when I try compiling your Configuration.h:

    In file included from Sprinter.cpp:5:0:
    Configuration.h:1:0: error: unterminated #ifndef

    I’m not having any compile issues with Rick’s Configuration.h. Do you know what might be wrong? I’ve tried adding one and two #endif at the end with no luck.

  3. BrazenArtifice says:

    Arrg. Thanks for catching this.

    an extra #endif at the end of the file should have fixed it.

    My fault for chopping out bits that aren’t useful for the MakerGear Prusa, and not testing. I was using Marlin at the time.

    I’ll fix it right away.
