A Raft is a horizontal latticework of filament that is located underneath your part. Your 3D printed part will be printed on top of this raft, instead of directly on the build platform surface.
Determines whether your model will be printed on a raft.
Sets how far above the raft your object is printed. Smaller values may make the raft harder to remove. Higher values may decrease the quality of your object's bottom surface.
Sets the distance between the outer edge of your object and the edge of the raft.
The first layers of the raft.
Sets the spacing between the lines of a raft's base layer.
Sets the length of the zig-zag pattern that forms the base of a raft.
Angle of the raft base layer(s), measured counterclockwise from the positive X axis.
A higher value will result in the lines of a raft's base layer being printed closer together; a lower value will result in lines printed farther apart. MakerBot recommends values between 0.80 and 0.90.
Sets extrusion width on the base layer(s) of a raft. Should be much wider than your nozzle width.
Sets the layer height on the base layer(s) of a raft. Should be much higher than your normal layer height.
The base layer of the raft is printed slowly, with thicker extrusion. More layers can help the raft stick if your build platform is very uneven.
Intermediate layers of the raft.
Angle of the raft interface layer(s), measured counterclockwise from the positive X axis.
A higher value will result in the lines of a raft's interface layer being printed closer together; a lower value will result in lines printed farther apart. MakerBot recommends values between 0.20 and 0.50.
Sets extrusion width on interface layers. This should be equal to or greater than the nozzle width.
Sets the layer height for interface layers.
The interface is the middle section between the raft base and the raft surface. This setting determines how many interface layers are printed.
The last layers of the raft.
Sets how many shells are printed on raft surface layers. Additional shells may make the raft easier to remove.
Angle of the raft surface layer(s), measured counterclockwise from the positive X axis.
Sets layer height for raft surface layers. MakerBot recommends values close to the default layer height.
Your printed object will rest on the surface layers of the raft. This setting determines how many surface layers are printed.
Sets how far the surface fill overlaps the innermost shell. A lower setting will result in more overlap.
When set to true, raftAligned forces all raft interface layers to run in the same direction. When set to false, the lines of extrusion on each raft interface layer will be rotated 90 degrees from the previous layer.
If your model has an overhang which is not supported by anything below, you need to add additional 3D printing support structures to ensure a successful print.
Determines whether your model will be printed with automatically generated support structures.
Set to true for easier removing support, set to false for sturdy well connected support.
Turn on Align Support for parallel walls of support. Turn it off for stronger, criss-crossing support structures.
Sets your object to print with an earlier style of support structures that surround your object, instead of the current minimal support.
A value of 1.00 will result in solid support structures; a lower value will result in the lines of the support structures being printed farther apart.
Sets the distance between the edge of the object and the outer edges of the supports. If it is set to 0.00, support structures will not extend farther than any supported overhang.
Sets the distance between the outer edge of your object and the support structures.
Support structures will be built under overhangs where the angle is a greater number of degress than the value set here. A value of 0 will result in support everywhere. A value of 90 will result in no support.
Turn on to build support under bridges shorter than the length specified in Maximum Bridge Length. Short bridges may not need extra support.
Bridging in 3D printing is an extrusion of material that horizontally links two raised points. The bridging settings affect areas of your print that are supported at both ends but not in the middle.
When set to true, the slicer will make sure that lines of extrusion that bridge gaps will always run between stable anchor regions. When set to false, none of the bridging settings below will be used.
A bridge is section of a print that is supported at both ends but not in the middle. If a bridge is longer than the length set here, the slicer will treat it like an unsupported overhang instead.
The bridge anchor settings determine which sections on an object can be used as stable anchor regions. If an anchor region is too narrow or too shallow, it will not provide a large enough base for the end of your bridge. Sections of your object narrower than the value set for bridgeAnchorMinimumLength or shallower than the value set for bridgeAnchorWidth will not be used as anchor regions.
Lines of extruded plastic on the first layer of a bridge are narrower than lines of extrusion that rest on another layer because they cannot be squashed into a lower layer. This setting offers the opportunity to print those lines closer together, so that they can overlap. MakerBot Desktop determines the amount of overlap by multiplying extrusion width by the value set for bridgeSpacingMultiplier and using that value as the expected extrusion width. This results in the slicer spacing the lines of extrusion as if they are smaller than they actually are. This feature is experimental and may not be helpful. To have the lines on the first layer of a bridge print with normal spacing, set bridgeSpacingMultiplier to 1.00.
The model properties affect print quality.
Determines the height of each layer.
Determines the number of outlines printed on each layer. If any section of your model doesn't have room for this many shells, that section will be printed with the number that do fit.
Vertices that produce features smaller than this area in square millimeters are collapsed.
Infill is the shape and amount of filament printed inside the object. This directly relates to the strength, weight and printing duration of your print.
Determines how solid the infill is. A setting of 0.00 results in a hollow object and a setting of 1.00 results in a solid one.
Sets the infill pattern for your print. The default hexagon pattern is strongest.
Orientation angle to rotate per layer for linear infill in degrees.
Orientation angle offset applied to the orientation range.
Orientation angle range (inclusive) for linear infill in degrees.
Sets how far the infill overlaps the innermost shell. A lower setting will result in more overlap.
Orientation angle to rotate per layer for solid fill in degrees.
Orientation angle range (inclusive) for solid fill in degrees.
The floor settings affect the solid layers that form the bottom of each print.
When enabled, this setting overrides the floorThickness setting and sets floor thickness to a specific number of layers. To disable this setting, change the setting name to floorLayerCount_disabled.
Sets the thickness of you model's solid floor.
The roof settings affect the solid layers that form the top of each print.
Extending roofs inside solid regions to support shells from layers above can help shells on sloped surfaces stay in place.
When enabled, this setting overrides the roofThickness setting and sets roof thickness to a specific number of layers. To disable this setting, change the name of the setting to roofLayerCount_disabled.
Sets the thickness of your model's solid roof.
The anchor settings affect the anchor that is printed on your build plate at the beginning of each print.
Amount of feedstock to extrude at start of anchor (mm).
Speed at which to make the anchor blob.
This setting defines the extrusion width of the portion of the anchor connecting the initial blob to the object or raft.
Spurs are single-walled sections of objects - places where the outlines are so close together that they take the form of a single line of extrusion. The spur settings affect how to create toolpaths for any very thin sections of your objects.
When set to true, the settings below will be used to create single walls where necessary. If set to false, sections of your object that are so thin that they require only a single extrusion width will not print at all.
Internal spurs are spurs that appear inside the outlines of your object. Sections of a print that narrow to a point will often result in internal spurs on inner shells. When set to true, segments of single extrusion width will be used to fill the gaps between two shells where possible. This feature is experimental.
Spur segments that are shorter than the value defined in this setting will be eliminated from the final toolpath.
These settings allow you to specify when spurs will be used. Spurs will not be used for sections wider than the maxSpurWidth or more narrow than the minSpurWidth. Sections wider than the maxSpurWidth will accommodate multiple extrusion widths. Sections narrower than the minSpurWidth will not be printed.
This setting allows spurs that almost touch to join by extending them by the amount set here.
Extrude at least this much filament between a restart and an ooze.
Determines which of the three basic profiles is used when you enter a layer height into the «Quality» tab in the «Settings» dialog in MakerBot Desktop. It is not used when slicing with a custom profile.
This setting limit the width of extrusion by overriding layerWidthRatio when necessary. By default layerWidthMinimum and layerWidthMaximum are set to the same value. This ensures that the layer width remains the same no matter what layer height is set.
Defines the ratio of extrusion width over layer height. If the layerWidthRatio produces an extrusion width between the value set for layerWidthMinimum and the value set for layerWidthMaximum, the extrusion width will be equal to the layerHeight multiplied by the layerWidthRatio.
This defines the space between each pair of adjacent shells. The number is a multiplier of the extrusion width. Set this under 1.00 to have the insets overlap, and over 1.00 for gaps between the insets. In general, it's best to have the insets overlap slightly.
If both a tight curve and part of a long, straight line are included in a Dynamic Speed Detection Window, the average change in degrees per millimeter may not be large enough to trigger a Dynamic Speed slowdown. This setting fixes this problem by splitting each long move into sections and treating them as separate moves. When set to true, every long move will be split into segments of the length set in the splitMinimumDistance setting. If splitting a long move does not trigger a Dynamic Speed change, the segments will be recombined. If you choose to split long moves into small segments, be aware that they may increase the size of your print file.
If a flick of at least this length cannot be made, don't flick.
Adjacent lines in roof, floor and solid infill need to overlap slightly to form a continuous surface. The MakerBot slicer determines the amount of overlap by multiplying extrusion width by the value set for gridSpacingMultiplier and using that value as the expected extrusion width. This results in the slicer spacing the lines of extrusion as if they are smaller than they actually are.
This setting multiplied by the base feedrates set in your extrusion profiles equals your minimum extrusion speed. Layers slowed down by the minLayerDuration setting will not print slower than the speed set here. Feedrates slowed down by the Dynamic Speed settings will not be affected by this setting.
Controls the speed of travel moves along the X and Y axes.
Controls the speed of travel moves along the Z axis.
When doSplitLongMoves is set to true, long moves will be split into segments of the length specified here.
Defines the starting position of X-axis when your print begins. If you are using a custom start.gcode file that moves your extruder to a final position different from the one described by this setting, you must change the position described here to match the final position set in your custom start.gcode.
Defines the starting position of Y-axis when your print begins. If you are using a custom start.gcode file that moves your extruder to a final position different from the one described by this setting, you must change the position described here to match the final position set in your custom start.gcode.
Defines the starting position of Z-axis when your print begins. If you are using a custom start.gcode file that moves your extruder to a final position different from the one described by this setting, you must change the position described here to match the final position set in your custom start.gcode.

Prints mixed-material support structures, where each part of the model is supported by structures printed in the same material.
Sets device settings.
When you use the MakerBot Slicer with MakerBot Desktop, you will assign objects to different extruders using the «Object Information» menu. When you call the MakerBot Slicer manually, this setting will determine which extruder will be used to build your object. On a machine with dual extruders, 0 is the right toolhead and 1 is the left toolhead. On a machine with a single extruder, the single toolhead is 0.
Sets default temperature for a single or right side extruder.
Two sections enclosed in braces under extruderProfiles allow you to change a number of settings for each of two extruders. If your MakerBot 3D printer has two extruders, the settings enclosed in the first set of braces apply to the right extruder and the settings enclosed in the second set of braces apply to the left extruder. If your MakerBot 3D printer has a single extruder, your extruder profile is the one enclosed in the first set of braces and the one in the second set of braces can be ignored.
Sets default temperature of for a left side extruder.
Lets you change the starting height of the extruder relative to the build plate.
Extrusion profiles allow you to specify different settings for certain components of your prints, such as infill and inner shells.
The fan settings determine what fan commands are inserted into your toolpath.
Turning the fan off during long travel moves reduces stringing. This value specifies whether this technique is applied.
This is the fraction of time in the fan modulation time window that must be spent extruding (not traveling) for the fan to turn on. Smaller values prefer the fan to be on, larger values prefer the fan to be off. Setting this value to 0.00 is equivalent to having the fan be always on, and setting it to 1.00 is equivalent to having the fan be always off.
A time window used for modulating the fan. Smaller values cause the fan to switch on and off more frequently. Larger values will ignore some fast and short travel moves to switch the fan less frequently.
Allows you to set an extruder fan speed. MakerBot 3D printers do not use this setting.
Turns on the active cooling fan during a print.
Layer to start using active cooling.
Changing the speed of movement when printing different parts of the model.
Select if you wish areas with small details and tight curves to be printed at a lower speed.
If true, gradually slow down over the detection window. If false, immediately change to the slower speed.
Toggles dynamic speed for shells other than the othermost.
Toggles dynamic speed for the outermost shell.
The dynamicSpeedCurvatureThreshold setting combines with the dynamicSpeedDetectionWindow setting to determine how tight a curve must be to trigger a reduction in speed. If the average change in angle over the distance set in dynamicSpeedDetectionWindow is larger than the number of degrees per millimeter set in dynamicSpeedCurvatureThreshold, the slicer will slow down that portion of the toolpath.
The distance along the path we see at one time. Smaller values are good for only slowing down around small, tight details. Larger values will detect detail over a longer distance, slow down earlier, and speed up later, but can miss some very small details.
How much slower than normal speed to print small, tight details.
When we transition between speeds, we can do linearly or using an S-like curve. This value controls the amount the curve is shaped like a line vs the amount it is S-like. A value of 0.00 is linear transition, and a value of 1.00 is an S-like transition. Values between 0.00 and 1.00 control the amount of S-like-ness.
To smoothly transition from regular print speed to slower dynamic slowdown we do so over a certain distance. This setting configures that distance in millimeters. This value is rounded to the nearest increment of splitMinimumDistance.
The leaky connection settings offer additional options for extruder behavior on short internal travel moves.
When true, do not extrude between adjacent infill lines. Which lines are considered adjacent is determined by adjacentFillLeakyDistanceRatio.
Two fill lines are considered adjacent when the connection between them is shorter than the product of this value and the extrusion width.
When true, do not extrude when transitioning from one shell to another. This helps reduce blobbing with large numbers of shells.
For a connection to be made leaky, the lengths of the extrusion paths immediately before and after must exceed this value. This applies to connections between shells, support, and infill.
Backlash occurs when there is some amount of slack on one of more of your 3D printer's axes. When the extruder changes directions, some small portion of the first movement in the new direction will be taken up by that slack, and the resulting move will be slightly shorter than intended. Backlash can affect dimensional accuracy.
When set to true, the settings below will attempt to compensate for backlash. When set to false, none of the backlash settings below will be used. This feature is experimental and use may result in some slight distortion in printed objects.
When you use the backlashFeedback setting, MakerBot Desktop compensates for increasingly small amounts of error over distance. The remaining error gets smaller and smaller, but is never fully compensated for. This setting fixes this problem by ending the backlash compensation when the remaining error becomes so small as to be insignificant. When the remaining error is smaller than the distance in millimeters set here, the slicer will stop compensating for backlash.
MakerBot Desktop compensates for feedback gradually in order to reduce distortion. It will compensate for a certain amount of feedback over the distance set in splitMinimumDistance. The amount of feedback compensated for in each segment of the length set by splitMinimumDistance is a percentage inverse to the number set here. For example, if the default backlashFeedback setting is 0.90 and the default splitMinimumDistance is 0.40 mm, the slicer will compensate for 10% of the remaining feedback error over the first 0.40 mm after the change in direction. Then it will compensate for 10% of the remaining error over the next 0.40 mm. This will continue until the size of the error meets or falls below the distance set in backlashEpsilon. If backlashFeedback is set to 0.00, the entire error will be compensated for immediately.
These settings tell MakerBot Desktop how much backlash the slicer should be compensating for. To determine if backlash is present, print a 20 mm calibration box (available under «File» > «Examples» in MakerBot Desktop) and measure the length and width of the printed box. If either the width (X) of your box is less than 20 mm, subtract that value from 20. Divide that number by two and enter the result into the appropriate backlash setting.
These settings tell MakerBot Desktop how much backlash the slicer should be compensating for. To determine if backlash is present, print a 20 mm calibration box (available under «File» > «Examples» in MakerBot Desktop) and measure the length and width of the printed box. If either the length (Y) of your box is less than 20 mm, subtract that value from 20. Divide that number by two and enter the result into the appropriate backlash setting.
The exponential deceleration settings allow you to use the oozing plastic at the end of a move before retraction.

Different 3D printers use different characters to indicate comments in Gcode. MakerBot Desktop's default settings are optimized for use with MakerBot 3D printers.
If you set to true, build progress will be displayed on the LCD panel of your 3D-printer.
Toolpaths created for MakerBot 3D printers up to and including the MakerBot Replicator 2X require short Gcode files appended to the beginning and end to do things like turn the heaters and off and home the build platform and extruder or extruders. By default, these files are generated by MakerBot Desktop. If you want to use a custom start or end Gcode file, use these settings to specify the locations of the files you want to use. To disable these settings, erase the file path currently specified or change the setting names to startGcode_disabled and endGcode_disabled.
