//// 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

//// Endstop Settings

//// AD595 THERMOCOUPLE SUPPORT UNTESTED... USE WITH CAUTION!!!!

//// PID settings:

#define PID_INTEGRAL_DRIVE_MAX 220

  // Uncomment the following line to disable heat management during moves
  //#define DISABLE_CHECK_DURING_MOVE
#endif
// 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.
#define DISABLE_CHECK_DURING_TRAVEL 1000

//// 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.
#define HEATER_USES_THERMISTOR

// 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.
