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.
Select to print your model on a raft.
Distance above the raft at which 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.
Distance between the outer edge of your object and the edge of the raft.
The first layers of the raft.
Spacing between the lines of a raft's base layer(s).
Length of the zig-zag pattern that forms the raft's base layer(s).

Your surface layers will rest on top of the raft's subsurface layers. This setting specifies how many sub surface layers are printed.
Your surface layers will rest on top of the subsurface layers. This setting specifies how thick sub surface layers are.
Sets how far above the raft the supports object is printed. Smaller values may make the support stick more firmly to the raft. Defaults to the raft model spacing if not set.
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.
Additional offset between the extruder and build plate when a raft is being printed.
Raft fill profiles for surface, solid, and sparse.
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.
Select to print your model with automatically generated support structures.
Select for less connected support structures which are easier to remove.
Select for parallel walls of support. Deselect for stronger, criss-crossing support structures.
Select to print with an earlier style of support structures that surround your object, instead of the current minimal support.
Lines of the support structures will be printed closer together at higher densities and farther apart at lower densities. A value of 1.00 will result in solid support structures.
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.
Distance between supports and the printed object in the horizontal plane.
Support structures will be printed 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.
Select to print your model with easy to remove supports.
Select to print support under all bridges.
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 the underside of a print that is supported at both ends but not in the middle. If a bridge is longer than the length set here, support will be printed underneath.
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.
Distance between the top-most layer of supports and the printed object in the horizontal plane.
Sets the layer height used for support structures. This layer height can be greater than the model layer height for faster printing.
Stop support slightly before model floors to allow for easier breakaway.
Extra x/y amount to clear support around model floors when support cutouts are used.
Control the additional droop distance between support roofs and the exposed underside features of your model. Smaller values make the support bind to the model more tightly, but may produce more precise model floors. Higher values make the support easier to remove, but might worsen the underside surface quality.
Pushes the bounds of the drooped breakaway portion of the model into or away from the supported regions of the model. By default the breakaway is directly adjacent to the supported model edge. Sensible values here are +-1 layer width - large insets will cause bad model layer adhesion, large outsets can cause unsupported or non-breakaway model floors.
Control the additional droop distance between support floors and the exposed upper layers of your model. Smaller values make the support bind to the model more tightly, higher values make the support easier to remove but less precise and stable.

Features smaller than this area in square millimeters are removed.
Start each layer from the object closest to a fixed location, rather than closest to where the previous layer ended.
X position of the point near which to start a layer when Fixed Layer Starting Point is true.
Y position of the point near which to start a layer when Fixed Layer Starting Point is true.
Start each shell at the vertex farmost in the direction specified by Shell Starting Point. If not selected, the starting point will be chosen for optimal ordering, and may cause the zipper to be a different place on every layer.
Controls roughly where the zipper will be placed. 0 points toward the back of the printer. The zipper clockwise as the angle increases.
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.
Specifies 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 maximum height of infill layers. This setting will be rounded to an integer multiple of the model layer height.

Orientation angle to rotate per layer for linear infill in degrees.
Orientation angle offset applied to the orientation range.

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.
Minimum layer height supported.
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.
Initial position of all axes of the bot.
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 true, exactly follow the path that was just printed backwards for flickDistance when doing a flick. If false, try to make a single move flickDistance long in the opposite direction of the last segment of the path, and fall back to following the path exactly if such a move would cross the outline.
Distance of the flick that is done before retracting.
Use advanced path planning techniques to minimize stringing.
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.
Maximum length of an extrusion made to avoid retraction. If avoiding a retraction would require a longer extrusion, we will retract and go to the closest object instead.
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.
Minimum reduction in total area required for adding a thick sparse infill layer.
When doSplitLongMoves is set to true, long moves will be split into segments of the length specified here.

Print 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.
Single or right side extruder temperature.
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.
Left side extruder temperature.
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.
Select to use active cooling fan during a print.
Active cooling fan power (% Max Power).
Layer at which to start using active cooling.
Changing the speed of movement when printing different parts of the model.
Select to print areas with small details and tight curves 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.
Breakaway support can cause horizontal defects to appear aligned with the top of supports due to Z axis backlash. These defects can be eliminated by compensating for the specified distance along the Z axis.
The exponential deceleration settings allow you to use the oozing plastic at the end of a move before retraction.
Enable precise control of speed at the end of paths to reduce stringing. Only works for 5th generation machines.
Exponential deceleration will not cause the speed to fall below this value.
During exponential deceleration, the extruder speed will slow from its initial speed to the product of the initial speed and this number.
