Define Documentation

Appends the linenumber after ever ok send, to acknowledge the received command. Uncomment for plain ok ACK if your host has problems with this

#define ALLOW_QUADSTEPPING   true

If you need frequencies off more then 30000 you definitely need to enable this. If you have only 1/8 stepping enabling this may cause to stall your moves when 20000Hz is reached.

#define ALWAYS_CHECK_ENDSTOPS   false

Used reference, normally ANALOG_REF_AVCC or ANALOG_REF_AREF for experts ANALOG_REF_INT_2_56 = 2.56V and ANALOG_REF_INT_1_1=1.1V inernaly generated.

#define ARC_SUPPORT   true
#define BAUDRATE   250000

enables quadratic component.

Uncomment to allow a quadratic advance dependency. Linear is the dominant value, so no real need to activate the quadratic term. Only adds lots of computations and storage usage. Communication speed.

  • 250000 : Fastes with errorrate of 0% with 16 or 32 MHz - update wiring_serial.c in your board files. See boards/readme.txt
  • 115200 : Fast, but may produce communication errors on quite regular basis, Error rate -3,5%
  • 76800 : Best setting for Arduino with 16 MHz, Error rate 0,2% page 198 AVR1284 Manual. Result: Faster communication then 115200
  • 57600 : Should produce nearly no errors, on my gen 6 it's faster than 115200 because there are no errors slowing down the connection
  • 38600

Overridden if EEPROM activated.

#define BEEPER_LONG_SEQUENCE   8,8
#define BEEPER_SHORT_SEQUENCE   2,2

Beeper sound definitions for short beeps during key actions and longer beeps for important actions. Parameter is is delay in microseconds and the secons is the number of repetitions. Values must be in range 1..255

#define DISABLE_E   false
#define DISABLE_X   false
#define DISABLE_Y   false
#define DISABLE_Z   true
#define DOUBLE_STEP_DELAY   1

If you reach STEP_DOUBLER_FREQUENCY the firmware will do 2 or 4 steps with nearly no delay. That can be too fast for some printers causing an early stall.

#define DRIVE_SYSTEM   0
#define ECHO_ON_EXECUTE

Sets time for echo debug.

You can set M111 1 which enables ECHO of commands send. This define specifies the position, when it will be executed. In the original FiveD software, echo is done after receiving the command. With checksum you know, how it looks from the sending string. With this define uncommented, you will see the last command executed. To be more specific: It is written after execution. This helps tracking errors, because there may be 8 or more commands in the queue and it is elsewise difficult to know, what your reprap is currently doing.

#define EEPROM_MODE   1

EEPROM storage mode.

Set the EEPROM_MODE to 0 if you always wan't to use the settings in this configuration file. If not, set it to a value not stored in the first EEPROM-byte used. If you later want to overwrite your current eeprom settings with configuration defaults, just select an other value. On the first call to epr_init() it will detect a mismatch of the first byte and copys default values into EEPROM. If the first byte matches, the stored values are used to overwrite the settings.

IMPORTANT: With mode <>0 some changes in configuration.h are not set any more, as they are taken from the EEPROM.

#define ENABLE_BACKLASH_COMPENSATION   true

Some boards like Gen7 have a power on pin, to enable the atx power supply. If this is defined, the power will be turned on without the need to call M80 if initially started.

#define EXT0_ADVANCE_K   0.0f

Faktor for the advance algorithm. 0 disables the algorithm. Overridden if EEPROM activated. K is the factor for the quadratic term, which is normally disabled in newer versions.

I-gain. Overridden if EEPROM activated.

#define EXT0_PID_INTEGRAL_DRIVE_MAX   140

The maximum value, I-gain can contribute to the output.

A good value is slightly higher then the output needed for your temperature. Values for starts: 130 => PLA for temperatures from 170-180°C 180 => ABS for temperatures around 240°C

The precise values may differ for different nozzle/resistor combination. Overridden if EEPROM activated.

#define EXT0_PID_INTEGRAL_DRIVE_MIN   60

lower value for integral part

The I state should converge to the exact heater output needed for the target temperature. To prevent a long deviation from the target zone, this value limits the lower value. A good start is 30 lower then the optimal value. You need to leave room for cooling. Overridden if EEPROM activated.

#define FEATURE_CONTROLLER   0

For displays and keys there are too many permutations to handle them all in once. For the most common available combinations you can set the controller type here, so you don't need to configure uicong.h at all. Controller settings > 1 disable usage of uiconfig.h

0 = no display 1 = Manual definition of display and keys parameter in uiconfig.h

The following settings override uiconfig.h! 2 = Smartcontroller from reprapdiscount on a RAMPS or RUMBA board 3 = Adafruit RGB controller 4 = Foltyn 3DMaster with display attached

#define FEATURE_FAN_CONTROL   true

#define GCODE_BUFFER_SIZE   2

Cache size for incoming commands.

There should be no reason to increase this cache. Commands are nearly immediately send to execution.

#define GENERIC_THERM1_BETA   4036

Beta value of thermistor

You can use the beta from the datasheet or compute it yourself. See http://reprap.org/wiki/MeasuringThermistorBeta for more details.

#define GENERIC_THERM1_MAX_TEMP   300

End Temperature for generated thermistor table

#define GENERIC_THERM1_MIN_TEMP   -20

Start temperature for generated thermistor table

#define GENERIC_THERM1_R0   100000

If defined, creates a thermistortable at startup.

If you dont feel like computing the table on your own, you can use this generic method. It is a simple approximation which may be not as accurate as a good table computed from the reference values in the datasheet. You can increase precision if you use a temperature/resistance for R0/T0, which is near your operating temperature. This will reduce precision for lower temperatures, which are not realy important. The resistors must fit the following schematic:

VREF ---- R2 ---+--- Termistor ---+-- GND
                |                 |
                +------ R1 -------+
                |                 |
                +---- Capacitor --+
                |
                V measured

If you don't have R1, set it to 0. The capacitor is for reducing noise from long thermistor cable. If you don't have have one, it's OK.

If you don't need the generic table, uncomment the following define. Reference resistance

#define GENERIC_THERM_NUM_ENTRIES   33

Number of entries in generated table. One entry takes 4 bytes. Higher number of entries increase computation time too. Value is used for all generic tables created.

#define GENERIC_THERM_VREF   5

Supply voltage to ADC, can be changed be setting ANALOG_REF below to different value.

#define HAVE_HEATED_BED   false

Set true if you have a heated bed conected to your board, false if not.

#define HEATED_BED_HEAT_MANAGER   1

Heat manager for heated bed: 0 = Bang Bang, fast update 1 = PID controlled 2 = Bang Bang, limited check every HEATED_BED_SET_INTERVAL. Use this with relais driven beds to save life

#define HEATED_BED_HEATER_PIN   HEATER_1_PIN

Pin to enable heater for bed.

#define HEATED_BED_MAX_TEMP   90
#define HEATED_BED_PID_DGAIN   40

Dgain. Overridden if EEPROM activated.

#define HEATED_BED_PID_IGAIN   0.9

I-gain Overridden if EEPROM activated.

The maximum value, I-gain can contribute to the output.

A good value is slightly higher then the output needed for your temperature. Values for starts: 130 => PLA for temperatures from 170-180°C 180 => ABS for temperatures around 240°C

The precise values may differ for different nozzle/resistor combination. Overridden if EEPROM activated.

lower value for integral part

The I state should converge to the exact heater output needed for the target temperature. To prevent a long deviation from the target zone, this value limits the lower value. A good start is 30 lower then the optimal value. You need to leave room for cooling. Overridden if EEPROM activated.

#define HEATED_BED_PID_MAX   255

What shall the printer do, when it receives an M112 emergency stop signal? 0 = Disable heaters/motors, wait for ever until someone presses reset. 1 = restart by resetting the AVR controller. The USB connection will not reset if managed by a different chip!

#define LOW_TICKS_PER_MOVE   250000

Cycles per move, if move cache is low.

This value must be high enough, that the buffer has time to fill up. The problem only occurs at the beginning of a print or if you are printing many very short segments at high speed. Higher delays here allow higher values in PATH_PLANNER_CHECK_SEGMENTS.

X, Y, Z max acceleration in mm/s^2 for printing moves or retracts. Make sure your printer can go that high! Overridden if EEPROM activated.

#define MAX_FEEDRATE_X   200

Maximum feedrate, the system allows. Higher feedrates are reduced to these values. The axis order in all axis related arrays is X, Y, Z Overridden if EEPROM activated.

#define MAX_FEEDRATE_Y   200
#define MAX_FEEDRATE_Z   40
#define MAX_HALFSTEP_INTERVAL   1999

The firmware supports trajectory smoothing. To acieve this, it divides the stepsize by 2, resulting in the double computation cost. For slow movements this is not an issue, but for really fast moves this is too much. The value specified here is the number of clock cycles between a step on the driving axis. If the interval at full speed is below this value, smoothing is disabled for that line.

#define MAX_HARDWARE_ENDSTOP_X   false
#define MAX_HARDWARE_ENDSTOP_Y   false
#define MAX_HARDWARE_ENDSTOP_Z   false
#define MAX_INACTIVE_TIME   0L

After x seconds of inactivity, the system will go down as far it can. It will at least disable all stepper motors and heaters. If the board has a power pin, it will be disabled, too. Set value to 0 for disabled. Overridden if EEPROM activated.

#define MAX_JERK   20.0

Maximum allowable jerk.

Caution: This is no real jerk in a physical meaning.

The jerk determines your start speed and the maximum speed at the join of two segments. It's unit is mm/s. If the printer is standing still, the start speed is jerk/2. At the join of two segments, the speed difference is limited to the jerk value.

Examples: For all examples jerk is assumed as 40.

Segment 1: vx = 50, vy = 0 Segment 2: vx = 0, vy = 50 v_diff = sqrt((50-0)^2+(0-50)^2) = 70.71 v_diff > jerk => vx_1 = vy_2 = jerk/v_diff*vx_1 = 40/70.71*50 = 28.3 mm/s at the join

Segment 1: vx = 50, vy = 0 Segment 2: vx = 35.36, vy = 35.36 v_diff = sqrt((50-35.36)^2+(0-35.36)^2) = 38.27 < jerk Corner can be printed with full speed of 50 mm/s

Overridden if EEPROM activated.

#define max_software_endstop_r   true

#define MOTHERBOARD   5
#define MOTOR_CURRENT   {48713,48713,42713,48713,42713}
#define MOVE_CACHE_LOW   10

Low filled cache size.

If the cache contains less then MOVE_CACHE_LOW segments, the time per segment is limited to LOW_TICKS_PER_MOVE clock cycles. If a move would be shorter, the feedrate will be reduced. This should prevent buffer underflows. Set this to 0 if you don't care about empty buffers during print.

#define MOVE_CACHE_SIZE   16

Number of moves we can cache in advance.

This number of moves can be cached in advance. If you wan't to cache more, increase this. Especially on many very short moves the cache may go empty. The minimum value is 5.

#define NUM_EXTRUDER   1

Number of extruders. Maximum 2 extruder.

#define NUM_TEMPS_USERTHERMISTOR0   28

Temperature range for target temperature to hold in M109 command. 5 means +/-5°C

Uncomment define to use force the temperature into the range for given watchperiod. Userdefined thermistor table

There are many different thermistors, which can be combined with different resistors. This result in unpredictable number of tables. As a resolution, the user can define one table here, that can be used as type 5 for thermister type in extruder/heated bed definition. Make sure, the number of entries matches the value in NUM_TEMPS_USERTHERMISTOR0. If you span definition over multiple lines, make sure to end each line, except the last, with a backslash. The table format is {{adc1,temp1},{adc2,temp2}...} with increasing adc values. For more informations, read http://hydraraptor.blogspot.com/2007/10/measuring-temperature-easy-way.html

If you have a sprinter temperature table, you have to multiply the first value with 4 and the second with 8. This firmware works with increased precision, so the value reads go from 0 to 4095 and the temperature is temperature*8.

If you have a PTC thermistor instead of a NTC thermistor, keep the adc values increasing and use themistor types 50-52 instead of 5-7! Number of entries in the user thermistortable 0. Set to 0 to disable it.

#define NUM_TEMPS_USERTHERMISTOR1   0

Number of entries in the user thermistortable 1. Set to 0 to disable it.

#define NUM_TEMPS_USERTHERMISTOR2   0

Number of entries in the user thermistortable 2. Set to 0 to disable it.

#define OPS_MIN_DISTANCE   0.8

Minimum distance for retraction.

If a travel move is shorter than this distance, no retraction will occur. This is to prevent retraction with infill, where the angle to the perimeter needs a short stop. Unit is mm. Overridden if EEPROM activated.

#define OPS_MODE   0

Sets the ops operation mode.

0: Off 1: Classic mode. Stop head, retract move to target, push filament back. 2: Fast mode. Retract during move, start pushing back the filament during move. For safty, we start at with a low speed and wait for the push back, before the pintmove starts. Normally there is some time needed to wait for the filament.

Overridden if EEPROM activated.

#define OPS_MOVE_AFTER   50.0

Move printhead only after x% of retract distance have been retracted.

Overridden if EEPROM activated.

#define OPS_RETRACT_BACKLASH   0.0

Backslash produced by extruder reversal.

If you are using a bowden extruder, you may need some extra distance to push the filament back into the original place. This is the value you enter here. Unit is mm. Overridden if EEPROM activated.

#define OPS_RETRACT_DISTANCE   1.5

Retraction distance in mm. If you want to enable OPS only sometimes, compile with OPS support and set retraction distance to 0. If you set it to e.g. 3 in your eeprom settings it is enabled. Overridden if EEPROM activated.

#define PID_CONTROL_RANGE   15

PID control only works target temperature +/- PID_CONTROL_RANGE. If you get much overshoot at the first temperature set, because the heater is going full power to long, you need to increase this value. For one 6.8 Ohm heater 10 is ok. With two 6.8 Ohm heater use 15.

#define RAMP_ACCELERATION   1

Comment this to disable ramp acceleration

#define RETRACT_DURING_HEATUP   true

If enabled you can select the distance your filament gets retracted during a M140 command, after a given temperature is reached.

#define SCALE_PID_TO_MAX   0

Set PID scaling.

PID values assume a usable range from 0-255. This can be further limited to EXT0_PID_MAX by to methods. Set the value to 0: Normal computation, just clip output to EXT0_PID_MAX if computed value is too high. Set value to 1: Scale PID by EXT0_PID_MAX/256 and then clip to EXT0_PID_MAX. If your EXT0_PID_MAX is low, you should prefer the second method.

#define SD_EXTENDED_DIR

Set to false to disable SD support: Show extended directory including file length. Don't use this with pronterface!

#define SKIP_M109_IF_WITHIN   2

Skip wait, if the extruder temperature is already within x degrees. Only fixed numbers, 0 = off

#define SKIP_M190_IF_WITHIN   3

Skip M190 wait, if heated bed is already within x degrees. Fixed numbers only, 0 = off.

#define STEP_DOUBLER_FREQUENCY   12000

The firmware can only handle 16000Hz interrupt frequency cleanly. If you need higher speeds a faster solution is needed, and this is to double/quadruple the steps in one interrupt call. This is like reducing your 1/16th microstepping to 1/8 or 1/4. It is much cheaper then 1 or 3 additional stepper interrupts with all it's overhead. As a result you can go as high as 40000Hz.

#define STEPPER_HIGH_DELAY   0

If your stepper needs a longer high signal then given, you can add a delay here. The delay is realized as a simple loop wasting time, which is not available for other computations. So make it as low as possible. For the most common drivers no delay is needed, as the included delay is already enough.

#define STEPPER_INACTIVE_TIME   120L

After x seconds of inactivity, the stepper motors are disabled. Set to 0 to leave them enabled. This helps cooling the Stepper motors between two print jobs. Overridden if EEPROM activated.

#define TEMP_PID   true

Include PID control for all heaters.

#define TIMER0_PRESCALE   64

Prescale factor, timer0 runs at.

All known arduino boards use 64. This value is needed for the extruder timing.

#define UI_AUTORETURN_TO_MENU_AFTER   30000

Time to return to info menu if x millisconds no key was pressed. Set to 0 to disable it.

#define UI_DISABLE_AUTO_PAGESWITCH   true

Uncomment if you don't want automatic page switching. You can still switch the info pages with next/previous button/click-encoder

#define UI_ENCODER_SPEED   1
#define UI_KEY_BOUNCETIME   10

bounce time of keys in milliseconds

#define UI_KEY_FIRST_REPEAT   500

Reduction of repeat time until next execution.

#define UI_LANGUAGE   1

Select the language to use. 0 = english 1 = german 2 = dutch

#define UI_PAGES_DURATION   4000

How many ms should a single page be shown, until it is switched to the next one.

#define UI_SET_EXTRUDER_FEEDRATE   2

#define UI_SET_MAX_HEATED_BED_TEMP   120
#define UI_SET_MIN_EXTRUDER_TEMP   160
#define UI_SET_MIN_HEATED_BED_TEMP   55
#define UI_VERSION_STRING2   "Mendel"
#define USE_ADVANCE

Enable advance algorithm.

Without a correct adjusted advance algorithm, you get blobs at points, where acceleration changes. The effect increases with speed and acceleration difference. Using the advance method decreases this effect. For more informations, read the wiki.

#define USE_OPS   1

Activate ooze prevention system.

The ooze prevention system tries to prevent ooze, by a fast retract of the filament every time printing stops. Most slicing software have already an option to do this. Using OPS_MODE=1 will in fact mimic this. This works good, but can increase printing time. To reduce the additional waiting time, the OPS has a fast mode, which performs the retraction during the travelling move. The only reason, your slicer doesn't do it, is because it can't tell. There is simple no G-Code command telling the firmware to do that.

You can always compile including OPS. Then you can disable/enable it anytime you want. To disable it set USE_OPS 0

Caution: Don't enable anti-ooze in your slicer if you are using this.

Value:
{\
  {1*4,864*8},{21*4,300*8},{25*4,290*8},{29*4,280*8},{33*4,270*8},{39*4,260*8},{46*4,250*8},{54*4,240*8},{64*4,230*8},{75*4,220*8},\

#define USER_THERMISTORTABLE1   {}
#define USER_THERMISTORTABLE2   {}
#define WAITING_IDENTIFIER   "wait"

Communication errors can swollow part of the ok, which tells the host software to send the next command. Not receiving it will cause your printer to stop. Sending this string every second, if our queue is empty should prevent this. Uncomment if you don't wan't this feature.
