// 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 with Makergear geared stepper extruder:
//float axis_steps_per_unit[] = {80,80,3200/1.25,1380};

//// Endstop Settings
#define ENDSTOPPULLUPS 1 // 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 1

//// ADVANCED SETTINGS - to tweak parameters

// 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.

// By default we set it to zeros.

//// PID settings:
// Uncomment the following line to enable PID support. This is untested and could be disastrous. Be careful.
//#define PIDTEMP 1
#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 1
//#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 240

// Select one of these only to define how the nozzle temp is read.
//#define HEATER_USES_AD595
//#define HEATER_USES_MAX6675

// Select one of these only to define how the bed temp is read.
//#define BED_USES_AD595

// Uncomment the following line to enable debugging. You can better control debugging below the following line
//#define DEBUG
#ifdef DEBUG
  //#define DEBUG_PREPARE_MOVE //Enable this to debug prepare_move() function
  //#define DEBUG_BRESENHAM //Enable this to debug the Bresenham algorithm
  //#define DEBUG_RAMP_ACCELERATION //Enable this to debug all constant acceleration info
  //#define DEBUG_MOVE_TIME //Enable this to time each move and print the result
  //#define DEBUG_HEAT_MGMT //Enable this to debug heat management. WARNING, this will cause axes to jitter!
  //#define DEBUG_DISABLE_CHECK_DURING_TRAVEL //Debug the namesake feature, see above in this file

    Hi Brazen,
    I am configuring my Marlin based on yours…..but i just realised that you use BAUDRATE at 250000. When I was on sprinter, I was using 115200…..which one should i use now? I am on RAMPS 1.4
    Thanks for the great resources btw.

      Hi Julio,

      You can use either baudrate. Just make sure you use the same baudrate in your printer control software that you set in the configuration.h file in Marlin and Sprinter.

      I use pronterface for printer control, and its’ baudrate selector is a pull-down field next to the Com port selector up in the top left of the screen.

      250000 works fine for me in both sprinter and marlin.
