//=============================Thermal Settings ============================
#define BED_CHECK_INTERVAL 5000 // ms between checks in bang-bang control
#define BED_HYSTERESIS 2 // Only disable heating if T>target+BED_HYSTERESIS and enable heating if T>target-BED_HYSTERESIS
* Thermal Protection protects your printer from damage and fire if a
* thermistor falls out or temperature sensors fail in any way.
* The issue: If a thermistor falls out or a temperature sensor fails,
* Marlin can no longer sense the actual temperature. Since a disconnected
* thermistor reads as a low temperature, the firmware will keep the heater on.
* The solution: Once the temperature reaches the target, start observing.
* If the temperature stays too far below the target (hysteresis) for too long (period),
* the firmware will halt the machine as a safety precaution.
* If you get false positives for "Thermal Runaway" increase THERMAL_PROTECTION_HYSTERESIS and/or THERMAL_PROTECTION_PERIOD
#define THERMAL_PROTECTION_HYSTERESIS 10 // Degrees Celsius
* Whenever an M104 or M109 increases the target temperature the firmware will wait for the
* WATCH_TEMP_PERIOD to expire, and if the temperature hasn't increased by WATCH_TEMP_INCREASE
* degrees, the machine is halted, requiring a hard reset. This test restarts with any M104/M109,
* but only if the current temperature is far enough below the target for a reliable test.
* If you get false positives for "Heating failed" increase WATCH_TEMP_PERIOD and/or decrease WATCH_TEMP_INCREASE
* WATCH_TEMP_INCREASE should not be below 2.
#define WATCH_TEMP_PERIOD 20 // Seconds
#define WATCH_TEMP_INCREASE 2 // Degrees Celsius
* Thermal Protection parameters for the bed are just as above for hotends.
* Whenever an M140 or M190 increases the target temperature the firmware will wait for the
* WATCH_BED_TEMP_PERIOD to expire, and if the temperature hasn't increased by WATCH_BED_TEMP_INCREASE
* degrees, the machine is halted, requiring a hard reset. This test restarts with any M140/M190,
* but only if the current temperature is far enough below the target for a reliable test.
* If you get too many "Heating failed" errors, increase WATCH_BED_TEMP_PERIOD and/or decrease
#define WATCH_BED_TEMP_PERIOD 180 // Seconds
#define WATCH_BED_TEMP_INCREASE 2 // Degrees Celsius
// this adds an experimental additional term to the heating power, proportional to the extrusion speed.
// if Kc is chosen well, the additional required power due to increased melting should be compensated.
#define DEFAULT_Kc (100) //heating power=Kc*(e_speed)
#define LPQ_MAX_LEN 50
* Automatic Temperature:
* The hotend target temperature is calculated by all the buffered lines of gcode.
* The maximum buffered steps/sec of the extruder motor is called "se".
* Start autotemp mode with M109 S<mintemp> B<maxtemp> F<factor>
* The target temperature is set to mintemp+factor*se[steps/sec] and is limited by
* mintemp and maxtemp. Turn this off by executing M109 without F*
* Also, if the temperature is set to a value below mintemp, it will not be changed by autotemp.
* On an Ultimaker, some initial testing worked with M109 S215 B260 F1 in the start.gcode
//#define AUTOTEMP
// Show Temperature ADC value
// Enable for M105 to include ADC values read from temperature sensors.
* High Temperature Thermistor Support
* Thermistors able to support high temperature tend to have a hard time getting
* good readings at room and lower temperatures. This means HEATER_X_RAW_LO_TEMP
* will probably be caught when the heating element first turns on during the
* preheating process, which will trigger a min_temp_error as a safety measure
* and force stop everything.
* To circumvent this limitation, we allow for a preheat time (during which,
* min_temp_error won't be triggered) and add a min_temp buffer to handle
* aberrant readings.
* If you want to enable this feature for your hotend thermistor(s)
* uncomment and set values > 0 in the constants below
// The number of consecutive low temperature errors that can occur
// before a min_temp_error is triggered. (Shouldn't be more than 10.)
// The number of milliseconds a hotend will preheat before starting to check
// the temperature. This value should NOT be set to the time it takes the
// hot end to reach the target temperature, but the time it takes to reach
// the minimum temperature your thermistor can read. The lower the better/safer.
// This shouldn't need to be more than 30 seconds (30000)

// A single Z stepper driver is usually used to drive 2 stepper motors.
// Uncomment this option to use a separate stepper driver for each Z axis motor.
// The next unused E driver will be assigned to the second Z stepper.
// Z_DUAL_ENDSTOPS is a feature to enable the use of 2 endstops for both Z steppers - Let's call them Z stepper and Z2 stepper.
// That way the machine is capable to align the bed during home, since both Z steppers are homed.
// There is also an implementation of M666 (software endstops adjustment) to this feature.
// After Z homing, this adjustment is applied to just one of the steppers in order to align the bed.
// One just need to home the Z axis and measure the distance difference between both Z axis and apply the math: Z adjust = Z - Z2.
// If the Z stepper axis is closer to the bed, the measure Z > Z2 (yes, it is.. think about it) and the Z adjust would be positive.
// Play a little bit with small adjustments (0.5mm) and check the behaviour.
// The M119 (endstops report) will start reporting the Z2 Endstop as well.
#define Z_DUAL_ENDSTOPS_ADJUSTMENT 0 // Use M666 to determine/test this value
// Enable this for dual x-carriage printers.
// A dual x-carriage design has the advantage that the inactive extruder can be parked which
// prevents hot-end ooze contaminating the print. It also reduces the weight of each x-carriage
// allowing faster printing speeds. Connect your X2 stepper to the first unused E plug.
// Configuration for second X-carriage
// Note: the first x-carriage is defined as the x-carriage which homes to the minimum endstop;
// the second x-carriage always homes to the maximum endstop.
#define X2_MIN_POS 80 // set minimum to ensure second x-carriage doesn't hit the parked first X-carriage

#define X2_HOME_DIR 1 // the second X-carriage always homes to the maximum endstop position
#define X2_HOME_POS X2_MAX_POS // default home position is the maximum carriage position
// However: In this mode the HOTEND_OFFSET_X value for the second extruder provides a software
// override for X2_HOME_POS. This also allow recalibration of the distance between the two endstops
// without modifying the firmware (through the "M218 T1 X???" command).
// Remember: you should set the second extruder x-offset to 0 in your slicer.
// There are a few selectable movement modes for dual x-carriages using M605 S<mode>
// Mode 0 (DXC_FULL_CONTROL_MODE): Full control. The slicer has full control over both x-carriages and can achieve optimal travel results
// as long as it supports dual x-carriages. (M605 S0)
// Mode 1 (DXC_AUTO_PARK_MODE) : Auto-park mode. The firmware will automatically park and unpark the x-carriages on tool changes so
// that additional slicer support is not required. (M605 S1)
// Mode 2 (DXC_DUPLICATION_MODE) : Duplication mode. The firmware will transparently make the second x-carriage and extruder copy all
// actions of the first x-carriage. This allows the printer to print 2 arbitrary items at
// once. (2nd extruder x offset and temp offset are set using: M605 S2 [Xnnn] [Rmmm])

//#define LIN_ADVANCE
#define LIN_ADVANCE_K 75
* Some Slicers produce Gcode with randomly jumping extrusion widths occasionally.
* For example within a 0.4mm perimeter it may produce a single segment of 0.05mm width.
* While this is harmless for normal printing (the fluid nature of the filament will
* close this very, very tiny gap), it throws off the LIN_ADVANCE pressure adaption.
* For this case LIN_ADVANCE_E_D_RATIO can be used to set the extrusion:distance ratio
* to a fixed value. Note that using a fixed ratio will lead to wrong nozzle pressures
* if the slicer is using variable widths or layer heights within one print!
* This option sets the default E:D ratio at startup. Use `M900` to override this value.
* Example: `M900 W0.4 H0.2 D1.75`, where:
* - W is the extrusion width in mm
* - H is the layer height in mm
* - D is the filament diameter in mm
* Example: `M900 R0.0458` to set the ratio directly.
* Set to 0 to auto-detect the ratio based on given Gcode G1 print moves.

* Use Trinamic's ultra quiet stepping mode.
* When disabled, Marlin will use spreadCycle stepping mode.
* Let Marlin automatically control stepper current.
* This is still an experimental feature.
* Increase current every 5s by CURRENT_STEP until stepper temperature prewarn gets triggered,
* then decrease current by CURRENT_STEP until temperature prewarn is cleared.
* Adjusting starts from X/Y/Z/E_CURRENT but will not increase over AUTO_ADJUST_MAX
* Relevant g-codes:
* M906 - Set or get motor current in milliamps using axis codes X, Y, Z, E. Report values if no axis codes given.
* M906 S1 - Start adjusting current
* M906 S0 - Stop adjusting current
* M911 - Report stepper driver overtemperature pre-warn condition.
* M912 - Clear stepper driver overtemperature pre-warn condition flag.
#define CURRENT_STEP 50 // [mA]
#define AUTO_ADJUST_MAX 1300 // [mA], 1300mA_rms = 1840mA_peak
* The driver will switch to spreadCycle when stepper speed is over HYBRID_THRESHOLD.
* This mode allows for faster movements at the expense of higher noise levels.
* STEALTHCHOP needs to be enabled.
* M913 X/Y/Z/E to live tune the setting
#define X_HYBRID_THRESHOLD 100 // [mm/s]
* Use stallGuard2 to sense an obstacle and trigger an endstop.
* You need to place a wire from the driver's DIAG1 pin to the X/Y endstop pin.
* If used along with STEALTHCHOP, the movement will be louder when homing. This is normal.
* X/Y_HOMING_SENSITIVITY is used for tuning the trigger sensitivity.
* Higher values make the system LESS sensitive.
* Lower value make the system MORE sensitive.
* Too low values can lead to false positives, while too high values will collide the axis without triggering.
* It is advised to set X/Y_HOME_BUMP_MM to 0.
* M914 X/Y to live tune the setting
* You can set your own advanced settings by filling in predefined functions.
* A list of available functions can be found on the library github page
