Revision as of 17:24, 7 December 2015

Slice Settings is located in Advanced Controls to the right of the 'Controls' tab.

CuraEngine Slice Settings

The slice settings in MatterControl are divided by three categories:

Print:

This is where the settings concerning the actual printed part are located. Things like, layer height, support material, and infill.

Filament:

This is where the settings concerning the filament are located. Things like temperature control and cooling.

Printer:

This is where settings concerning the actual hardware are located. Things like bed size, nozzle diameter, and custom Gcode.

We'll be breaking them down by sub-category, in order, assuming that "Show All Settings" is checked.

If a setting isn't visible, make sure "Show All Settings" is checked.

Layers/Perimeters

Layer Height

Layer Height: This determines the quality of the print in its entirety. The thinner the layer, the higher the resolution. This also is the biggest factor when determining print time.

First Layer Height: This determines the height of your first layer, which is useful in making sure your print has a good starting point. Remember, the vast majority of prints will fail within the first layer.

Vertical Shells

Perimeters (minimum): This determines how many vertical layers you have on your print. i.e. how thick your walls will be.

Spiral Vase: Force the print to have only one vertical layer and gradually increase the extruder height during the print. Only one part can be printed at a time with this feature.

Horizontal Shells

Number of Solid Layers on the Top: This determines how many of the top layers will be solid. This is useful when the infill is lower.

Number of Solid Layers on the Bottom: This determines how many solid layers will be printed before the printer begins to use infill.

Infill

Fill Density: This determines the density of your infill within the print. This affects print time, total weight, and filament used.

Speed

Speed for Print Moves

Perimeters: This determines how fast your printer will travel when extruding perimeters.

Infill: This determines how fast your printer will travel when extruding infill.

Speed for non Print Moves

Travel: How fast your printer will move when it is not otherwise extruding.

Modifiers

First Layer Speed: This determines how fast the printer will extrude during the first layer. This is typically a percentage of the previous settings, as extruding the first layer more slowly helps the print get started.

Skirt and Brim

Skirt

Loops: This value determines how many loops around the print will be extruded at the start.

Distance from Object: How far from the print the loops will be extruded.

Minimum Extrusion Length: Sets the minimum amount of filament to use when drawing the skirt loops. This will cause enough skirt loops to be drawn to use this amount of filament.

Support Material

Generate Support Material: Checking the box enables the printing of support material with whatever settings you have enabled.

Overhang Threshold: This determines the angle at which your print will have support material generated.

Options

Pattern Spacing: This determines the density of your support material. Essentially the infill for it.

X and Y Distance: How far the infill will rest away from your print on the X and Y axis. The farther away it is, the easier it is to disconnect.

Z Distance: How far the infill will rest away from your print on the Z axis. The farther away it is, the easier it is to disconnect.

Filament

Diameter: Here you would enter the diameter of your filament. This setting is usually already entered when you first connect to a printer, giving it the default settings from the manufacturer.

Temperature

Extruder Other Layers: This determines the extruder temperature for the duration of the print.

Bed Other Layers: For printers with heat controlled beds, this determines the bed temperature for the duration of the print.

Cooling

Fan Speed

Min Fan Speed: This value determines the slowest speed that your fan is allowed to go, by percentage.

Max Fan Speed: This value determines the fastest speed that your fan is allowed to go, by percentage.

Disable Fan For The First: This determines how many layers should go by without the fan being enabled.

Cooling Thresholds

Slow Down If Layer Print Time Is Below: This value determines the minimum amount of time a layer is allowed to take, in seconds. If the layer finishes before the allotted time, the extruder will move away and stop until it is allowed to resume.

General

Size and Coordinates

Bed Size: These values determine how long your bed is along each axis, by millimeters.

Print Center: These values determine where the center of your bed lies.

Build Height: How high your bed can lower or raise, along the Z axis.

Bed Shape: This determines the shape of your bed, either rectangular or circular.

Custom G-Code

Start G-Code: This is the place where you can input custom G-code, and whatever is input here will go into effect as soon as you start a print.

End G-Code: This is the place where you can input custom G-code, and whatever is input here will go into effect as soon as a print finishes.

Extruder 1

Size

Nozzle Diameter: This is where you input the diameter of the nozzle, in millimeters.

Retraction

Length: This value determines how far your filament will be retracted with each qualifying non-printing move, in millimeters.

Speed: This Value determines how fast your filament will be retracted, and re-extruded, in millimeters.

Minimum Travel After Retraction: This value determines the minimum distance of a non-printing move that will result in a retraction.

Slic3r Slice Settings

Layers/Perimeters

Layer Height

Layer Height: This determines the quality of the print in its entirety. The thinner the layer, the higher the resolution. This also is the biggest factor when determining print time.

First Layer Height: This determines the height of your first layer, which is useful in making sure your print has a good starting point. Remember, the vast majority of prints will fail within the first layer.

Vertical Shells

Perimeters (minimum): This determines how many vertical layers you have on your print. i.e. how thick your walls will be.

Spiral Vase: Force the print to have only one vertical layer and gradually increase the extruder height during the print. Only one part can be printed at a time with this feature.

Horizontal Shells

Number of Solid Layers on the Top: This determines how many of the top layers will be solid. This is useful when the infill is lower.

Number of Solid Layers on the Bottom: This determines how many solid layers will be printed before the printer begins to use infill.

Quality (slower slicing)

Generate Extra Perimeters When Needed: Allow slic3r to generate extra perimeters when needed for sloping walls.

Avoid Crossing Perimeters: Attempts to minimize the number of perimeters crossing. This can help with oozing or strings.

Start At Concave Point: Make sure the first point on a perimeter is a concave point.

Start At Non Overhang: Make sure the first point on a perimeter is not an overhang.

Thin Walls: Detect when walls are too close together and need to be extruded as just one wall.

Advanced

Randomize Starting Points: Start each new layer from a different vertex to reduce seams.

External Perimeters First: Normally external perimeters are printed last, this makes them go first.

Infill

Fill Density: The ratio of material to empty space ranged 0 to 1. 0 would be no infill, 1 is solid infill

Fill pattern: The pattern used on the inside portions of the print.

Top/Bottom Fill Pattern: The pattern used on the bottom and top layers of the print.

Advanced

Infill Every: Sets which layers will receive infill. This should normally stay set to 1 to make strong parts.

Only Infill Where Needed: Creates infill only where it will be used as internal support.

Solid Infill Every: Sets how often a layer will be forced to be solid infilled. Zero will result in normal infill throughout.

Fill Angle: Sets the starting angle of the infill.Not used when bridging.

Solid Infill threshold Area: Forces solid infill for any area less than this amount.

Only Retract When Crossing Perimeters: Prevents retraction while within a printing perimeter.

Do Infill Before Perimeters: Sets infill to happen before perimeters are created.

Output Options

Sequential Printing

Complete Individual Objects: Each individual part is printed to completion then the extruder is lowered back to the bed and the next part is printing.

Extruder Clearance Radius: This is used to figure out how far apart individual parts must be printed to allow them to be completed before printing the next part.

Infill Extruder: The index of the extruder to use for infill.

Support Material Extruder: The index of the extruder to use for support material.

Support Interface Extruder: The index of the extruder to use for support material interface layers.

Ooze Prevention

Temp Lower Amount: This is the amount to lower the temperature of an extruder that is not currently printing.

Advanced

Extrusion Width

Default Extrusion Width: Leave this as 0 to allow automatic calculation of extrusion width.

First Layer: Setting this to greater than 100% can often help the first layer have better adhesion to the print bed.

Perimeters: Leave this as 0 to allow automatic calculation of extrusion width.

Infill: Leave this as 0 to allow automatic calculation of extrusion width.

Solid Infill: Leave this as 0 as to allow automatic calculation of extrusion width.

Support Material: Leave this as 0 as to allow automatic calculation of extrusion width.

Flow

Bridge Flow Ratio: This controls the ratio of material extruder during bridging. Reducing this slightly can help bridging by stretching the filament more. Using a fan can also help greatly.

Other

Threads: The number of CPU cores to use while doing slicing. Increasing this can slow down your machine.

Resolution: The minimum feature size to consider from the model. Leave at 0 to use all the model detail.

Extrusion Axis: This is the identifier used in the gcode to specify the extruder.

Optimize Overhangs: Experimental feature that attempts to improve overhangs using the fan and bridge settings.

Filament

Diameter: This should be set to the actual diameter of the filament you are using on your printer. Measure 5 times with calipers, throw out the top and bottom, and average the remaining 3.

Extrusion Multiplier: All extrusions are multiplied by this value. Increasing it above 1 (1.1 is a good max value) will increase the amount of filament being extruded; decreasing it (.9 is a good min value) will decrease the amount being extruded.

Temperature (°C)

Extrude First Layer: The temperature to set the extruder to before printing the first layer of a part. This printer will wait until this temperature has been reached before printing.

Extruder Other Layers The temperature to set the extruder to after the first layer has been printed.

Bed First Layer: The temperature to set the bed to before printing the first layer. The printer will wait until this temperature has been reached before printing. Set to 0 to eliminate bed temperature commands.

Bed Other Layers: The temperature to set the bed to after the first layer has been printed. Set to 0 to eliminate bed temperature commands.

Cooling

Enable

Keep Fan Always On: This will force the fan to remain on throughout the print. In general you should have this off and just enable auto cooling.

Enable Auto Cooling: Turns on and off all cooling settings (all settings below this one).

Fan Speed

Min Fan Speed: This is the minimum fan speed that your fan can run at.

Max Fan Speed: This is the maximum speed that your fan can run at.

Bridging Fan Speed: The fan speed to use during bridging.

Disable Fan For The First: The number of layers for which the fan will be forced to remain off.

Cooling Thresholds

Enable Fan If Layer Print Time Is Below: If a layer is estimated to take less than this print, the fan will be turned on.

Slow Down If Layer Print Time Is Below If a layer is estimated to take less than this to print, the movement speed will be reduced to try and make the layer take this long to print.

Min Print Speed: This is the minimum speed that the printer will reduce to, to make the layer tak long enough to satisfy the min layer time.

General

Z Offset: This value will be added to all of the z positions of the created gcode.

Bed Shape: The shape of the physical bed.

Firmware

G-Code Flavor Some firmware uses different g and m codes. Setting this ensures that the output gcode will use the correct commands.

Use Relative E Distances Normally you will want to use absolute e distances. Only check this if you know your printer needs relative e distances.

Use Arcs: Use firmware arcs rather than multiple segments for curves.

Use G0: Use G0 for moves rather than G1.

Advanced

Use Firmware Retraction: Request the firmware to do retractions rather than specify the extruder movements directly.

Vibration Limit: This is to help reduce vibrations during printing. If your printer has a resonance frequency that is causing trouble, you can set this to try and reduce printing at that frequency.

Custom G-Code

Start G-Code: This GCode will be inserted into the output right after the temperature setting. If you have the commands to set temperature in this section they will not be generated outside of this section. You can also include values from other settings such as [first_layer_temperature]

End G-Code: This GCode will be inserted at the end of all automatic output. (the very end of the gcode commands.

Layer Change G-Code: This gcode will be inserted right after the change in z height for the next layer.

Tool Change G-Code: This gcode will be inserted after every tool change
