== Queue Errors ==

=== Too Big to Render ===

''Cause:'' This error message is in reference to the size of the STL file, not the physical dimensions of the part. Your part is probably either very complicated or has an excessive amount of detail, resulting in a large file size. It will still print, however you will not be able to preview it beforehand.

''Solution:'' Reduce the number of polygons in the model. Reducing larger models (250,000+ polygons) to 100,000 generally allows them to slice well and causes no significant loss to printable resolution. Here's a link to a good tutorial using Meshlab: http://www.shapeways.com/tutorials/polygon_reduction_with_meshlab

== Slice Errors ==

=== Slice Error Review Settings ===

''Cause:'' Occurs when one or more slicer settings are invalid. Also a known issue with certain versions of Slic3r.

''Possible Solutions:'' 

*Review settings for any invalid parameters. 
*Try a different [[Options/Slice Engine|Slice Engine]]
*Use a previous version of MatterControl like 1.3: [[Release Notes#1.3.0]]

=== 'Layer Height' must be less than or equal to the 'Nozzle Diameter'. ===

''Cause:'' The [[Settings/General/Layers-Surface/Layer Height/Layer Height|Layer Height]] is set to a value greater than the [[Settings/Printer/Extruder/Extruder X/Nozzle Diameter|Nozzle Diameter]].

''Solution:'' Set [[Settings/General/Layers-Surface/Layer Height/Layer Height|Layer Height]] to a value less than or equal to [[Settings/Printer/Extruder/Extruder X/Nozzle Diameter|Nozzle Diameter]].

=== 'First Layer Height' must be less than or equal to the 'Nozzle Diameter'. ===

''Cause:'' The [[Settings/General/Layers-Surface/Layer Height/First Layer Height|First Layer Height]] is set to a value greater than the [[Settings/Printer/Extruder/Extruder X/Nozzle Diameter|Nozzle Diameter]].

''Solution:'' Set [[Settings/General/Layers-Surface/Layer Height/First Layer Height|First Layer Height]] to a value less than or equal to [[Settings/Printer/Extruder/Extruder X/Nozzle Diameter|Nozzle Diameter]].

=== 'First Layer Extrusion Width' must be less than or equal to the 'Nozzle Diameter' * 4. ===

''Cause:'' The [[Settings/Filament/Extrusion/Extrusion Width/First Layer|First Layer Extrusion Width]] is set to a value greater than 4 times the [[Settings/Printer/Extruder/Extruder X/Nozzle Diameter|Nozzle Diameter]].

''Solution:'' Set [[Settings/Filament/Extrusion/Extrusion Width/First Layer|First Layer Extrusion Width]] to a value less than or equal to 4 times the [[Settings/Printer/Extruder/Extruder X/Nozzle Diameter|Nozzle Diameter]].

=== 'First Layer Extrusion Width' must be greater than 0. ===

''Cause:'' The [[Settings/Filament/Extrusion/Extrusion Width/First Layer|First Layer Extrusion Width]] is set to a value of 0 or less.

''Solution:'' Set [[Settings/Filament/Extrusion/Extrusion Width/First Layer|First Layer Extrusion Width]] to a value greater than 0.

=== The Minimum Fan Speed can only go as high as 100%. ===

''Cause:'' The [[Settings/Filament/Cooling/Fan Speed/Minimum Fan Speed|Minimum Fan Speed]] is set to a value greater than 100%.

''Solution:'' Set [[Settings/Filament/Cooling/Fan Speed/Minimum Fan Speed|Minimum Fan Speed]] to a value of 0-100%.

=== The Maximum Fan Speed can only go as high as 100%. ===

''Cause:'' The [[Settings/Filament/Cooling/Fan Speed/Maximum Fan Speed|Maximum Fan Speed]] is set to a value greater than 100%.

''Solution:'' Set [[Settings/Filament/Cooling/Fan Speed/Maximum Fan Speed|Maximum Fan Speed]] to a value of 0-100%.

=== The Extruder Count must be at least 1. ===

''Cause:'' The [[Settings/Printer/Features/Hardware/Extruder Count|Extruder Count]] is set to a value less than 1.

''Solution:'' Set [[Settings/Printer/Features/Hardware/Extruder Count|Extruder Count]] to a value of 1 or more.

=== The Fill Density must be between 0 and 1. ===

''Cause:'' The [[Settings/General/Infill/Infill/Fill Density|Fill Density]] is set to a value less than 0 or greater than 100% (or 1, if using ratio).

''Solution:'' Set [[Settings/General/Infill/Infill/Fill Density|Fill Density]] to a value greater than 0 and less than or equal to 100% (or 1, if using ratio).

=== Solid Infill works best when set to LINES. ===

''Cause:'' The [[Settings/General/Infill/Infill/Infill Type|Infill Type]] selected is not compatible with solid infill and will causing extrusion issues. 

''Solution:'' Either set [[Settings/General/Infill/Infill/Infill Type|Infill Type]] to LINES or change the [[Settings/General/Infill/Infill/Fill Density|Fill Density]] to a value less than 100% (or 1, if using ratio).
