The speed multiplier applies to all types of moves. The lowest possible setting is 0.25 and the highest possible is 3.0.\n<h2>Extrusion Multiplier</h2>\nDuring an active print, the extrusion multiplier modifies the extrusion flow rate, allowing you to increase or decrease the amount of plastic laid down.\nThis variable is different from that of the Extrusion Multiplier slice setting and will work in conjunction with it. For example, if the slicer setting is set at 1.06 and then the slider in Controls is used during the print and set to 1.08, the total result will be a multiplier of 1.1448 (1.06 * 1.08).\n<h1>Firmware Updates</h1>\nIf your printer has an Arduino Mega 2560 based microcontroller, you can use the firmware updater to upload new firmware to it.\n<img src=https://www.matterhackers.com/mattercontrol/'https://lh3.googleusercontent.com/3C166BaJZFQUNHtfeMaQprsOCN7RGvSs4xacVWpz-N8E0JnA26kBEc--egSQf1OOYudlYcGAKLrg3-BxTKUyQXEAPw=s0' title='' alt='' onload='imageLoaded(this)' data-image-loaded='false'>\nIf your printer is officially supported by MatterHackers (for instance the Pulse), the firmware updater will automatically check your firmware version and alert you if an update is available.

The plastic will also be able to flow better, but this will also increase stringing and oozing.

It can also improve detail slightly. However it will also make the material harder to extrude. Too low and the plastic will not extrude at all. Lower temperatures will also reduce how well the layers bond to each other, making the print weaker and also causing splitting between the layers.\nThere are a number of other factors which will affect the proper printing temperature as well.\nEach type of printer is different, and may be slightly better or worse at transferring heat to the filament. Different types of printers may also read different temperatures in the same situation due to different placement of the sensor.\nEven among the same types of material, different spools may require different temperatures because they are different colors or are made by different brands.

A layer cooling fan is used to cool off the plastic as soon as it comes out of the nozzle. This ensures that it hardens quickly and holds it's shape. If a layer above is being printed while the layer below is still soft, it will deform. If you have inadequate cooling it will be most apparent on overhangs and sharp corners. Overhangs will tend to curl up and become very messy underneath. Sharp corners will become rounded and blunt.\nFan settings are heavily dependent on the material you are printing. Some materials, like PLA, respond very well to cooling. For PLA you will want the fan running basically all the time. However, other materials do not react well to cooling. For instance, with ABS it can cause the layers to split apart from each other (delamination). In this case you only want to use the fan when absolutely necessary.\nMatterControl controls the speed of your layer cooling fan based on how long each layer will take to print. Layers with a small area will take less time to print. Thus, there will be less time for them to cool off and harden before the layer above is printed. So more fan power will be necessary.

The Extra Length On Restart option compensates for this by extruding a small amount of extra material in addition to the normal unretract, thus making up for whatever material may have leaked.\nThis setting will depend on the material you are printing, since some materials are runnier than others (less viscous) and will leak more.\nRecommended Baseline: \nUnits: millimeters (mm) \n\n<h1>Time For Extra Length</h1>\nDuring a travel move, the plastic does not leak from the nozzle all at once. It happens over time. There will be more leakage during a long travel move than a short one. Therefor, more extra extrusion will need to be done after a long move in order to reprime the nozzle.\nThis setting allows you to control how much extra extrusion is done on restart based on how long the travel move took. This setting is the amount of time it take for the nozzle to fully drain. Any moves that take less than this time will get proportionally less Extra Length On Restart. If zero, the full length will always be used.\nRecommended Baseline: \nUnits: seconds (s)\n<h1>Speed</h1>\nThe speed the extruder will move to retract the filament.\nThis should be the maximum speed your extruder is capable of. This should be fast so that the pressure is relieved as fast as possible and so that the nozzle does not linger in one spot too long while the retraction is happening. This can leave a blob.\nHowever, going to fast will cause the motor to skip steps.\nRecommended Baseline: 35 mm/s \nUnits: millimeters per seconds (mm/s) \nG-Code Replacement Variable: <code>retract_speed</code>\n<h1>Z Lift</h1>\nThis function lifts the nozzle during retraction, which ensures that the nozzle will not be dragged across the top of the print during travel moves.\nGenerally Z Lift should not be used, however sometimes it may be beneficial to set it to 1 or 2 layer thicknesses (0.2 - 0.4 mm). This reduces the likelihood of the nozzle colliding with any buildups of plastic while traveling, which can cause layer shifting. It will also stop the clunk-clunk-clunk noise as the nozzle crosses over the infill.\nRecommended Baseline: 0 mm \nUnits: millimeters (mm) \n\n<h1>Minimum Travel Requiring Retraction</h1>\nThis is one of several settings that control when retractions will be performed. This setting prevents retractions from being done on short travel moves. It sets the minimum travel distance where a retraction will definitely be performed. However, retractions may still be done for shorter travel moves depending on the conditions. <a class='article-link' data-path='slice-settings/filament/#retract-when-changing-isla' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/filament/#retract-when-changing-isla'>Retract When Changing Islands</a> takes precedence over this setting.\nGenerally you should have <a class='article-link' data-path='slice-settings/filament/#retract-when-changing-isla' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/filament/#retract-when-changing-isla'>Retract When Changing Islands</a> and <a class='article-link' data-path='slice-settings/filament/../general/layers-surface#avoid-crossing-perimet' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/general/layers-surface#avoid-crossing-perimet'>Avoid Crossing Perimeters</a> turned on. In this case, this setting will mainly only have an effect when moving from one part of the infill to the other. Stringing will not be visible, but retractions are still beneficial here since they will ensure that the nozzle is primed when it starts printing the next infill line.\nThis should normally be set to a large distance, since otherwise it may lead to too frequent retraction which can cause jamming.\nRecommended Baseline: 20 mm \nUnits: millimeters (mm) \n\n<h1>Retract When Changing Islands</h1>\nIslands are two areas of a layer which are not connected. If this option is on, then a retraction will be performed when the nozzle is traveling from one island to another. This setting takes precedence over <a class='article-link' data-path='slice-settings/filament/#minimum-travel-requiring-retract' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/filament/#minimum-travel-requiring-retract'>Minimum Travel Requiring Retraction</a> but not <a class='article-link' data-path='slice-settings/filament/#minimum-extrusion-requiring-retract' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/filament/#minimum-extrusion-requiring-retract'>Minimum Extrusion Requiring Retraction</a>.\nStringing primarily occurs when traveling between islands, so it is recommended to always have this option turned on.\nThis picture shows a layer with two islands. The red and blue circles indicate retraction and unretraction happening as the nozzle travels between them.\n<img src=https://www.matterhackers.com/mattercontrol/'https://lh3.googleusercontent.com/E65EfrFDhhe71Tgb9jUNGiaZ--ywuCAiUgFxyEgjoeismEZvsU_JJcdQTmEZm1N1T6dTEwOdD7Sq1HbrVbL1PjEwh_A' title='' alt='' onload='imageLoaded(this)' data-image-loaded='false'>\nRecommended Baseline: On \n\n<h1>Minimum Extrusion Requiring Retraction</h1>\nThis setting is used to control how frequently retractions are allowed to occur. Performing retractions too frequently can cause underextrusion (due to the nozzle not being fully primed) or jamming. This setting ensures that a certain amount of filament gets extruded before the next retraction is allowed to occur. This setting takes precedence over both <a class='article-link' data-path='slice-settings/filament/#minimum-travel-requiring-retract' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/filament/#minimum-travel-requiring-retract'>Minimum Travel Requiring Retraction</a> and <a class='article-link' data-path='slice-settings/filament/#retract-when-changing-isla' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/filament/#retract-when-changing-isla'>Retract When Changing Islands</a>.\nThis setting should be set to the smallest length possible. If you have confidence in your hot end and extruder, then you can set it to 0. However if you notice your printer has trouble keeping when retractions happen frequently, then you should try increasing this setting in increments of 0.01 mm.\nRecommended Baseline: 0.05 mm \nUnits: millimeters (mm)\n<h1>Length on Tool Change</h1>\nThis option is only available if your printer has multiple extruders\nThis is the distance that the filament will be retracted when switching from one extruder to another.

Too much of an overlap can cause blobs or other artifacts on the surface of your print.\nRecommended Baseline: 50% \nUnits: millimeters (mm) or percent of nozzle diameter (%)\n<h1>Fill Thin Gaps</h1>\nWhen the space between perimeters is very small (less than one nozzle diameter wide), it is not possible to fill it with normal infill.

A smaller number will create more layers and more vertical accuracy but also a slower print.\nThe Layer Thickness is exactly that \u2013 the height of each individual layer of plastic that will be printed. Most FFF style 3D printers offer layer heights between .1mm - .4mm. Don\u2019t know what height you should print at? This picture shows the difference between various layer heights.\n<img src=https://www.matterhackers.com/mattercontrol/'https://lh3.googleusercontent.com/RM8-abWZ8pDZERBg9HpmvViw9Hjr6NqI8IWAQbmQ9RSk-W8juDSAuQrZsyPQYYiHAY-FZnBNskJCFK6vUh-0O5yN0Q=s0' title='' alt='' onload='imageLoaded(this)' data-image-loaded='false'>\nIt\u2019s difficult to see layer lines at .1mm whereas the layer lines are plainly visible at .35mm. With these frogs, the .35mm frog took approximately 40 minutes to print. The .1mm frog took 3.5 hours. The first thing you need to decide is what surface quality do you want. If you want a high quality, smooth finish, you will need to print small layer heights. If surface finish isn\u2019t important and you want to print quickly, larger layer heights work great.\nIf you\u2019re unsure of what height to start with, .20mm offers a good combination of surface finish and print time for most prints.\nIt\u2019s important to note that low layer heights (< .15mm) require excellent bed leveling and machine calibration in order to successfully print.\nRecommended Baseline: 0.2 mm \nUnits: millimeters (mm)\nWarning: The layer thickness cannot exceed the diameter of your nozzle.\n<h1>First Layer Thickness</h1>\nThe thickness of the first layer of the print. A first layer thicker than the default layer height can ensure good adhesion to the build plate, since it means more material will be extruded and more material provides more bed adhesion. A thicker first layer also allows for more variation in the height of the bed.\nRecommended Baseline: 0.3 mm \nUnits: millimeters (mm) or percent of normal Layer Thickness (%)\n<h1>Perimeters</h1>\nPerimeters are the loops that form the outer walls of your print. These are sometimes also referred to as shells. This cube has 3 perimeters.\n<img src=https://www.matterhackers.com/mattercontrol/'https://lh3.googleusercontent.com/iHmXp0HTWA-DL_OryLlZ5LPpJpHsL9Sc4aKM2RJVeyG1oUoyj8khNoVhQsAXtV_dv1PLmzpgE2p48sYRTBIyHeFC=w250' title='' alt='' onload='imageLoaded(this)' data-image-loaded='false'>\nPerimeters bear most of the load that an object is under. Adding more perimeters will make a print stronger than increasing the fill density.\nPerimeters are generally printed at a slower speed than infill. Often, most of your print time will be spent doing perimeters. You may consider using fewer perimeters to speed up the print.\nThis can be specified as count or as thickness in millimeters (mm). For instance, if you set the perimeters to 1.0 mm, then enough loops will be created to make the walls 1 mm thick.\nRecommended Baseline: 3 \nUnits: count or millimeters (mm)\n<h1>Top Solid Layers</h1>\nThese are the layers that form a solid surface on the top of the print. \nIf you are using thinner layers then more top layers will be required to form a solid surface with no gaps. For this reason, we recommend specifying a thickness in millimeters (mm) instead of a number of layers.\nRecommended Baseline: 0.8 mm \nUnits: count or millimeters (mm)\n<h1>Bottom Solid Layers</h1>\nThese are the layers that form a solid surface on the bottom of the print. Generally fewer bottom layers are required than top layers, since the bottom layers do not have to bridge over the infill.\nRecommended Baseline: 0.6 mm \nUnits: count or millimeters (mm)\n<h1>Fill Density</h1>\n3D prints are hardly ever done completely solid. Instead, they are partially hollow with a pattern on the inside. This inside area is called the infill. You can choose the density of the infill pattern, from 0% (completely hollow) to 100% (completely solid).\n<img src=https://www.matterhackers.com/mattercontrol/'https://lh3.googleusercontent.com/dsfLpykwPboH8yf9pWXPaaT0CuJ_JjaJCk6-9R9ZgXap1lVyBo8Ggsz1vDnv_LzHzZuT3e6MHbl6k1obToNOsJwe=s0' title='' alt='' onload='imageLoaded(this)' data-image-loaded='false'> \n<img src=https://www.matterhackers.com/mattercontrol/'https://lh3.googleusercontent.com/BZFi0mgNMHrjtYB4SmRUL3CcxCSgV10uX8Xb4s-Thsf9zZv1gkgRFujsfmRoqpmEoX1KRg66sm1WXHpVTGbmTlW3iw=s0' title='' alt='' onload='imageLoaded(this)' data-image-loaded='false'>\nMore infill will make a print stronger, but it will also use more material and take longer to print. Generally it is advised to use as little infill as possible. Most parts will be fully functional with about 10 - 15% percent infill. For very large prints you should try to go even lower than that.\nUsually to have a strong part, you only need about 35% infill. In general, there isn\u2019t much strength benefit beyond 50%.\nIf you wish to make your print completely solid, we do not advise going above 85 - 90% infill. Beyond this we have noticed a tendency for prints to be overfilled. A better method for making completely solid prints is to use a very large number of perimeter loops.\nRecommended Baseline: 20% \nUnits: percentage (ex. 20%) or decimal (ex. 0.20)\n<h1>Infill Type</h1>\nThe geometric pattern used for the infill. Triangle infill uses the most efficient path, which makes it the fastest to print. It is also generally the strongest pattern. However some of the other patterns (like the hexagon) are more aesthetically pleasing. You might choose these if your infill will be visible, for instance if you are using a translucent filament. Lines or concentric infill are also better when using exceptionally high fill densities (> 50%).\nThis article has more information on <a href=https://www.matterhackers.com/"https://www.matterhackers.com/news/mattercontrol-delivers-optimized-hexagon-infill/">MatterControl's optimized hexagonal infill</a>.\nRecommended Baseline: Triangles \nOptions: \n Grid \n Triangles \n Hexagon \n Lines \n* Concentric", "path": "slice-settings/general/general", "title": "General", "children": []}, {"content": "<h1>Avoid Crossing Perimeters</h1>\nPrevents the nozzle from crossing outside of the perimeters when it is traveling from one place to another.

If a layer does not have enough time to cool and harden before the next one starts printing, then it will deform. In order to prevent this, MatterControl can slow down the printing speed of layers which would normally take very little time to print. This gives the layer more time to harden. It increases the time it takes to print small objects but it can also substantially improve print quality.\nIf you have inadequate cooling it will be most apparent on overhangs and sharp corners. Overhangs will tend to curl up and become very messy underneath. Sharp corners will become rounded and blunt.\nThese settings control when layers are slowed down and by how much.

In order for it to work the bridge needs to be printed at the right speed, and there must be adequate cooling. In addition, your material, temperature, nozzle diameter, and layer thickness all have an effect.

The travel speed is one of the most important settings for reducing stringing and oozing. This should be set as fast as your printer can go. 80 mm/s is safe for most printers, however many printers (such as deltas or others with bowden extruders) can go as high as 200 mm/s.\nSince travel moves are the fastest moves the printer makes, they are the most likely to cause layer shifting.

This gives the support more structure and makes it stronger. Depending on your print, this can make the supports easier or harder to remove.\nRecommended Baseline: On\n<h1>Interface Layers</h1>\nInterface layers go at the top of the supports. They are solid layers that provide a flat surface for the object to be printed on top of. Using interface layers will give you a smoother bottom surface on your print, but may make the supports more difficult to remove, especially in tight areas.\nThis setting controls how many interface layers are used (if any). You can specify it in a number of layers or as a thickness in millimeters.\nIf using interface layers, it is especially important to have a well tuned <a class='article-link' data-path='slice-settings/support/#air-' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/support/#air-'>air gap</a>, otherwise you will not be able to remove the interface layers from your print.\nIf you have a multi extrusion printer, you can use the <a class='article-link' data-path='slice-settings/support/#support-interface-extru' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/support/#support-interface-extru'>support interface extruder</a> setting to choose which material the interface layers are printed with.\nRecommended Baseline: 2 \nUnits: count or millimeters (mm) \nSee Also: <a class='article-link' data-path='slice-settings/support/support-interface-extru' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/support/support-interface-extru'>Support Interface Extruder</a>\n<h1>X and Y Distance</h1>\nThe space between the side of the support structures and the side of the print. This should be large enough that the sides of the supports are not touching and bonding with the object. This ensures that only the top of the support structures are touching the print, ensuring that they are easy to remove.\nRecommended Baseline: 2 mm \nUnits: millimeters (mm)\n<h1>Air Gap</h1>\nThe air gap is the space between the top of the support material and the bottom of the print. Air gap is the most critical support material setting, since it controls how well the support structures will stick to your print.\nThe larger the air gap, the easier it will be to remove the support material. However, it will also make the bottom surface of your print messier. A smaller air gap will give a smoother, higher quality bottom surface, but also make the support material harder to remove.\nChoosing the right air gap requires a lot of experimentation, and it is heavily dependent on the material you are printing. Materials that typically haver stronger interlayer adhesion, like PLA, will require a larger air gap.\nUnlike other slicers, which simply skip layers, MatterControl takes a unique approach to the air gap. For the first layer of the print above the support material, the nozzle is lifted by the air gap distance. Since the nozzle is higher than it normally would be for that layer, the plastic falls a short distance onto the support material below, and cools a little while it is falling. By adjusting the air gap, you can precisely control how much the plastic cools while it falls and thus how well it sticks to the support material below.\nFor subsequent layers, the nozzle drops back down to the height it would be at otherwise. The air gap only affects the part of the first layer that is directly above the support material. Other parts of the layer will be printed at the normal height.\nThis animation shows the air gap in action. Remember that even though the first layer of the print appears to be in the middle of a higher layer, in reality the plastic will just fall down onto the support below.\n<img src=https://www.matterhackers.com/mattercontrol/'https://lh3.googleusercontent.com/Ray4qnvUbPSbeJBPTqENVsVT4ecJSUN4EaK42bzGSySa6N87Cpxf9rbcfOQdIrZTYS5A4surELn1lnMW6_tK6GBvSA' title='' alt='' onload='imageLoaded(this)' data-image-loaded='false'>\nIf you are using dissolvable support material, then the air gap should be 0. This ensures that the supports will be bonded properly and you will get the smoothest surface finish after they are dissolved.\nRecommended Baseline for PLA: 0.6 mm \nRecommended Baseline for ABS: 0.4 mm \nUnits: millimeters (mm)\n<h1>Support Type</h1>\nThe geometric pattern to use for the support structures. Lines is the most common pattern and makes the support easier to remove, however Grid provides more structure.\nRecommended Baseline: Lines \nOptions: \n Lines \n Grid\n<h1>Pattern Spacing</h1>\nThe space between the lines of the support pattern. A smaller spacing will make the support pattern more dense. Generally you want this to be as large as possible so that it is easier to break apart the supports. Making the support structures less dense will also reduce the amount of material wasted and make the print take less time. However, it will also cause more sagging on the bottom of the print. This should be close to your printer's maximum <a class='article-link' data-path='slice-settings/support/../speed/speed#brid' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/speed/speed#brid'>bridging</a> distance.\nRecommended Baseline: 8 mm \nUnits: millimeters (mm)\n<h1>Infill Angle</h1>\nThe angle at which the support material lines will be drawn, relative to the X axis.\nRecommended Baseline: 45\u00b0 \nUnits: degrees CCW from the X axis (\u00b0)\n<h1>Support Material Extruder</h1>\nThis option is only available if your printer has multiple extruders\nAllows you to choose which material is used for printing the support structures. This allows you to use dissolvable support material in multi-extrusion printers.\nDissolvable support materials (like PVA and HIPS) are preferable because they are easier to remove and leave behind a completely smooth surface. They also allow you print more complex and intricate shapes, because the material can be dissolved out of areas that you would not be able to break it out of by hand.\nExtruders are numbered starting with 1.\nUnits: extruder index\n<h1>Support Interface Extruder</h1>\nThis option is only available if your printer has multiple extruders\nAllows you to choose which material is used for printing the <a class='article-link' data-path='slice-settings/support/#interface-lay' href=https://www.matterhackers.com/mattercontrol/'/mattercontrol/support/slice-settings/support/#interface-lay'>interface layers</a>.

It all depends on what kind of print you are going for. If you want a print with a smooth finish and very fine details, you want a layer height of 0.1 - 0.2. If you want something a little rougher, perhaps a part in a bigger assembly, a layer height of .21 - 0.3 is more suited to your needs. You can of course have a larger layer height, but you cannot make a layer higher than the diameter of the nozzle.\n<h1>How much infill should I use?</h1>\nThe amount of infill in your part directly relates to how solid it is. Would you like a completely solid part? 100% infill is what you need. Something hollow? 0% infill will leave you with nothing but the outside layers. Usually to have a strong part, you only need about 35% infill. Most parts will be fully functional with about 15% percent infill. For really big parts, a smaller percentage is recommended, as increasing it unnecessarily can waste materials and increase print time.\n<h1>How do I stop the fan from coming on during printing?</h1>\nSet both the Minimum Fan Speed and Maximum Fan Speed to 0.\n<h1>What does support material do?</h1>\nWhen you check the Generate Support Material box, your print will contain support material.

Thus, when you bring your designs into MatterControl they will be the wrong scale.\n</li>\n<li>\nThe best solutions is to figure out how to get your design software to export STL files in millimeters. In SolidWorks, for instance, the Save As dialog has an Options button, that allows you to set many parameters for exporting an STL.\n</li>\n<li>\nIf you cannot get your design software to do this, though, you can still rescale the part once you have it in MatterControl.
