New page

== Original Documentation ==
The original documentation for the Reprap application Preferences is located at http://reprap.org/wiki/Java_Software_Preferences_File. This page attempts to clarify their function and interactions.

This page is a work in process and contains large parts of text taken from the above source, which is covered by the [http://www.gnu.org/copyleft/fdl.html|GNU Free Documentation License 1.2].

= General Preferences =
== Communications with Printer ==
=== BaudRate=57600 ===
The communications speed between the host computer and the RepRap microcontroller.
=== CommsDebug=false ===
Setting this true will cause each message to and from the RepRap machine also to be written to System.out.
=== Port(name)=/dev/ttyUSB0 ===
The port on the host computer that is connected to the RepRap machine. On Linux machines this will be something like /dev/ttyUSB0, on Windows it will be something like COM5. Be careful that there is no trailing or leading blank spaces in the port name, because it will make the port not recognize.
== Printer Parameters ==
=== DumpX(mm)=130, DumpY(mm)=5 ===
The position at which the extrude head can be run for a time to purge itself. See Extruder''n''_Purge below.
=== FinishX(mm)=10, FinishY(mm)=190 ===
The position to which the machine will move at the end of a build.
=== MaxXYAcceleration(mm/minute/minute)=1200000 ===
This is the maximum rate at which the machine can accelerate horizontally (i.e. in X and Y). As G Codes are in mm/minute, this is in the rather eccentric unit of mm/minute2. If you want to run at constant speed, or you have RepRap firmware that does not support accelerations, setting this negative will turn off XY accelerations for the whole machine (regardless of the similar values for the extruders - see below).

When this is positive, the software generates G-codes that treat the feedrate as just another dimension which changes proportionally as the move progresses. That is to say, it generates code like this:

<tt>G1 F1500.0</tt>

<tt>G1 X23.9 Y39.7 Z0.2526 F3000.0</tt>

So, for example, the second line is saying move to the specified coordinates, and accelerate from 1500.0 mm/minute at the start of the move to 3000.0 mm/minute while doing so. To make a movement at constant speed, simply set the feedrate first:

If this is zero, the generated GCode assumes that the printer itself can manage acceleration, and will try as much as possible to perform each move at (and never above) the feedrate specified on the that move. Note that the latter behaviour is the standard way to interpret F words in GCode.
=== MaxZAcceleration(mm/minute/minute)=3000 ===
This is the maximum rate at which the machine can accelerate vertically (i.e. in Z). As G Codes are in mm/minute, this is in the rather eccentric unit of mm/minute2. If you want to run at constant speed, or you have RepRap firmware that does not support accelerations, setting this negative will turn off Z accelerations for the whole machine.
=== MaximumFeedrateX(mm/minute)=3000 ===
The fastest speed that the X axis can be driven at without stalling or missing steps.
=== MaximumFeedrateY(mm/minute)=3000 ===
The fastest speed that the Y axis can be driven at without stalling or missing steps.
=== MaximumFeedrateZ(mm/minute)=50 ===
The fastest speed that the Z axis can be driven at without stalling or missing steps. Note, if you're experimenting, that moving up against gravity is harder than moving down, which will lead to a slower value. Use that.
=== SlowXYFeedrate(mm/minute)=1500.0 ===
When accelerating in X and Y, this decides what speed the machine can do as a standing start. That is to say, at this speed the steppers won't lose steps if they just start running. Thus it is also the speed at which the machine goes round a right-angled corner, for example (as that stops X and starts Y, or vice versa).
=== SlowZFeedrate(mm/minute)=5.0 ===
When accelerating in Z, this decides what speed the machine can do as a standing start. That is to say, at this speed the steppers won't lose steps if they just start running.
=== WorkingX(mm)=200, WorkingY(mm)=200, WorkingZ(mm)=140 ===
The lengths of movement in the three directions.
== Extrusion Control Model ==
=== FiveD=true ===
When this is false, the software generates G-codes to control the X, Y, and Z movement of the machine and separate codes to control the extruders by setting their extrusion speed (using Gxxx) and starting/stopping extrusion (using Mxxx) as required.

When this is true, the software generates G-codes that treat the extrusion as just another dimension called the E axis. That is to say, it generates code like this:

<tt>G1 X23.9 Y39.0 Z0.2526 E66.5 F3000.0 ;print segment</tt>

<tt>G1 X23.9 Y39.7 Z0.2526 E67.2 F3000.0 ;print segment</tt>

So, for example, the second line is saying move 0.7mm in Y from where you last were and extrude 0.7mm of filament while doing so, all at 3000 mm/minute.
== Overall Print Settings ==
=== BedTemperature(C)=55 ===
This sets the temperature to set the heated bed to but our printer is not equipped with a heated bed so this setting has no effect other than altering the GCode.
=== FoundationLayers=-1 ===
The number of layers of material to put down under the object being built before building proper starts. Set this to -1 to suppress the laying down of foundations. The structure of the foundation is determined by the [[#Foundation Structure Settings]] in the Extrusion Profile selected for the object to be printed.
=== InterLayerCooling=true ===
Setting this true causes RepRap to turn on the cooling fan between layers to freeze/set the build material being used. See Extruder''n''_CoolingPeriod(s) below. It also has the effect of causing the machine to re-zero itself in X and Y between each layer. This is a good idea, so - if you don't want cooling, still set this true but set the cooling period negative.
=== PathOptimise=false ===
This takes more time over computing the movement of the RepRap machine when generating GCode files so that when the movements are actually executed in the machine they run faster. In particular, it attempts to reduce in-air movements. If you just want to print a one-off of something, set this false. If you're going to print the same file lots of times, set it true.
=== Shield=true ===
When set true, this causes a wiper shield to be built alongside the parts being laid down. If the write head returns to the origin between layers, then this shield tends to remove any dribble from the nozzle before the nozzle starts laying down the part itself. Allow a blank space of 6mm in X and Y between the origin and the southwest corner of the object(s) being built for the shield to be constructed in.
== Extrusion Profiles ==
=== NumberOfExtruders=3 ===
Specifies the number of Extrusion Profiles, and thus the number of families of Extruder''n''_''Xxxx'' settings.

=== Debug=false ===

Setting this true will cause each action the host makes the RepRap do to be written to System.out.

= Extrusion Profile Preferences =
In the Preferences, all the settings for each Extrusion Profile are linked by its number between 0 and NumberOfExtruders-1 which is embedded within the setting name.
== Extruder Profile Name ==
=== Extruder''n''_MaterialType(name)=PLA ===
The name by which this Extrusion Profile is know when loading an object into the 3D viewer and when referenced as the Infill or Support Extrusion Profile.
== General Physical Extrusion Properties ==
=== Extruder''n''_Address=0 ===
The address of the extruder. These addresses are used by the RepRap firmware to decide what physical device the host is talking to.
=== Extruder''n''_ArcCompensationFactor(0..)=8 ===
When the extruder moves in an arc, too much material is laid down on the inside, and not enough on the outside. See [http://reprap.org/bin/view/Main/ArcCompensation this page] for an explanation of what this does.
=== Extruder''n''_ArcShortSides(0..)=1 ===
When the extruder moves in an arc, too much material is laid down on the inside, and not enough on the outside. See [[ArcCompensation|this page]] for an explanation of what this does.
=== Extruder''n''_CoolingPeriod(s)=0.1 ===
The time to turn the cooling fan on between layers. Set this negative to suppress cooling between layers. See InterLayerCooling above.
=== Extruder''n''_ExtrudeRatio(0..)=1 ===
If you are using the 4D firmware, this decides how much extrudate actually to lay down for a given movement. Thus if you set this to 0.7 and the head moves 100mm, then 70mm of extrudate will be deposited in that move. You can use this to control how fat or thin the extrudate trail is, though the machine should be set up so that this factor is 1.0.
=== Extruder''n''_ExtrusionDelayForLayer(ms)=600 ===
For the first use of the extruder in a layer the time delay between turning on the extruder motor and starting to move the extruder to lay down material. See also ValveDelayForLayer (below).
=== Extruder''n''_ExtrusionDelayForPolygon(ms)=500 ===
For the second and all subsequent use of the extruder in a layer the time delay between turning on the extruder motor and starting to move the extruder to lay down material. See also ValveDelayForPolygon (below).
=== Extruder''n''_ExtrusionHeight(mm)=0.3 ===
The depth of each layer. This value should be the same for all extruders in the machine at any one time.
=== Extruder''n''_ExtrusionOverRun(mm)=-1 ===
The distance before the end of a sequence of infill or outline depositions to turn off the extruder motor. See also ValveOverRun (below). Set this negative to keep running to the end.
=== Extruder''n''_ExtrusionPWM(0..1)=-1 ===
This controls the current to the extruder stepper motor, and hence its power. It sets the PWM ratio for the drive electronics. A value of 1 gives maximum current (be very careful not to burn out motors and control electronics with high values). A value of 0 disables the motor. If you set this to -1 (the default) then the motor uses the extruder's on-board potentiometer to set its current. Once again, be careful of turning this up too high (clockwise).
=== Extruder''n''_ExtrusionSize(mm)=0.7 ===
The width of the filament laid down by the extruder.
=== Extruder''n''_ExtrusionSpeed(mm/minute)=3000 ===
This sets the rate at which the extrudate exits the nozzle in millimeters per minute when the extruder is running in thin air (i.e. not building, or running the delay at the start of a layer or polygon - see above).

''Legacy. On PIC-based extruders it sets the PWM signal to send the extruder motor, as a fraction of 255. See also Extruder''n''_t0 (below).''

In either case, if there is no motor in use, set this negative.

''Legacy. On earlier extruders it sets the PWM signal to send the extruder motor, as a fraction of 255. See also Extruder''n''_t0 (below).''

=== Extruder''n''_ExtrusionTemp(C)=190 ===
The temperature to run the extruder at. 190oC is a good temperature for polylactic acid. For ABS use 240oC.
=== Extruder''n''_FastEFeedrate(mm/minute)=8000.0 ===
When the extruder reverses to retracts its filament (and moves forward from a retraction) there is almost no resistance to the filament's movement, so it can move fast. This is the speed to use for these. See also Extruder''n''_Reverse(ms).
=== Extruder''n''_FastXYFeedrate(mm/minute)=3000.0 ===
The fastest that this extruder can plot. This is the speed that the system will accelerate writing up to when accelerations are enabled. The system takes the minimum of this vale and the equivalent value for the machine overall when extruding.
=== Extruder''n''_Lift(mm)=0 ===
When doing in-air non-extruding movements, lift the extruder by this distance above the surface being created. This will slow building down, and is not normally needed
=== Extruder''n''_MaxAcceleration(mm/minute/minute)=1200000.0 ===
The fastest acceleration that this extruder can handle. Set this negative if the extruder must write at a constant speed. The system takes the minimum of this value and the equivalent value for the machine overall when extruding.
=== Extruder''n''_OffsetX(mm)=0, Extruder''n''_OffsetY(mm)=0, Extruder''n''_OffsetZ(mm)=0 ===
The offset of the extruder from (0, 0, 0) when the extruder is parked in X and Y. This is used to get multiple extruders in registration.
=== Extruder''n''_Purge(ms)=10000 ===
The time to run the extruder to purge it. This happens at the dump location (see above).
=== Extruder''n''_Reverse(ms)=400 ===
The time to reverse the extruder motor when it is turned off, drawing the extrudate back into it and reducing dribble.
=== Extruder''n''_SlowXYFeedrate(mm/minute)=1500.0 ===
The speed that the machine can do a standing start from when using this extruder. That is, turning on the X and/or Y steppers at this speed will not lose steps.
=== Extruder''n''_ValveDelayForLayer(ms)=200 ===
For extruders with valves. For the first use of the extruder in a layer the time delay between opening the extruder valve and starting to move the extruder to lay down material. See also ExtrusionDelayForLayer (above).
=== Extruder''n''_ValveDelayForPolygon(ms)=200 ===
For the second and all subsequent use of the extruder in a layer the time delay between opening the extruder valve and starting to move the extruder to lay down material. See also ExtrusionDelayForPolygon (above).
=== Extruder''n''_ValveOverRun(mm)=-1 ===
The distance before the end of a sequence of infill or outline depositions to close the extruder valve. See also ExtrusionOverRun (above). Set this negative to run to the end.
=== Extruder''n''_ValvePulseTime(ms)=-500 ===
The time to pulse the valve to open or close it. Set this negative if no valve is in use.
== 3D View window settings ==
=== Extruder''n''_ColourB(0..1)=0.6, Extruder''n''_ColourG(0..1)=0.3, Extruder''n''_ColourR(0..1)=0.3 ===
The colour of objects made by the material in this extruder in the 3D View window.
== Shell (Outline) Extrusion Properties ==
=== Extruder''n''_NumberOfShells(0..N)=1 ===
Normally (when this is 1) RepRap puts one outline round each layer before infilling it. You can create multiple outlines (or none) by changing this value.
=== Extruder''n''_OutlineSpeed(0..1)=0.9 ===
The fraction of the fastest extruder XY speed to do the outline at. See also FastXYFeedrate (above).
== Infill Extrusion Properties ==
These properties control how this Extrusion Profile behaves when generating Infill.
=== Extruder''n''_EvenHatchDirection(degrees)=45 ===
The angle in degrees to use to infill even-numbered layers.
=== Extruder''n''_ExtrusionBroadWidth(mm)=2.0 ===
The gap between the infill zig-zag pattern used to fill the interior of an object when coarse infill is being used. Set this negative to suppress coarse infill.
=== Extruder''n''_ExtrusionInfillWidth(mm)=0.6 ===
The gap between the infill zig-zag pattern used to fill the interior of an object when fine infill is being used.
=== Extruder''n''_InfillOverlap(mm)=0.2 ===
The amount to make the infill and outline overlap. This causes the two to weld together. You can set it negative and make a gap instead.
=== Extruder''n''_InfillSpeed(0..1)=1 ===
The fraction of the fastest extruder XY speed to do the infill at. See also FastXYFeedrate (above).
=== Extruder''n''_MiddleStart=true ===
When set true, this causes the system to start plotting outline patterns around objects from in the middle of their hatch infill, using a few of the hatch lines to do this. At the end of the outline, the head moves back to the start point. This means that the outline is clean, without dribble at the start and end. That happens in the middle of the solid, where it usually doesn't matter. Setting this false suppresses this behaviour, and the outlines are plotted as-is.
=== Extruder''n''_OddHatchDirection(degrees)=-45 ===
The angle in degrees to use to infill odd-numbered layers.
== Foundation Structure Settings ==
=== Extruder''n''_ExtrusionFoundationWidth(mm)=2 ===
The gap between the infill zig-zag pattern used to fill the interior of the foundations (if any).
=== Extruder''n''_ExtrusionLastFoundationWidth(mm)=2 ===
The gap between the infill zig-zag pattern used to fill the interior of the last layer of the foundations (if any).
== Infill and Support selection ==
=== Extruder''n''_InFillMaterialType(name)=PLA-infill ===
The name of the Extrusion Profile to use for infill. This is commonly the same actual extruder used for the outline shell, but this separate logical extruder allows you to set different parameters for infill and outline. Or you can outline in one material and infill with another, of course. Finally, you can make an outline material simply name itself as its own infill.
=== Extruder''n''_SupportMaterialType(name)=PLA-support ===
The name of the Extrusion Profile to use to support overhangs made from this material. You can set this the same as the material itself, then it will use the material to support itself. But - even if you want this - you will probably want different parameters (such as infill width) for the support build. To do this just copy all the material extruder's parameters, changing the extruder number and material name. You will then have two logical extruders driving the same physical extruder and can set their parameters as differently as you like.

If you don't want support material to be used at all under overhangs for this material, set Extruder''n''_SupportMaterialType(name)=null.
