Printing with Slic3r

You can find Slic3r settings that have produced decent print results here. You might want to check out "Infill", "Skirt and Brim" and "Support Material" settings under "Print Settings". These might not be available until you enable Advanced mode from Slic3r main Preferences (Slic3r -> Preferences in Os X).

• Provided settings have 40% infill and honeycomb pattern. This can be changed from "Print Settings" -> "Infill"
• Provided settings have only 5mm brimm. This can be changed from "Print Settings" -> "Skirt and Brimm"
• By default Slic3r doesn't create support material bridges, this can be enabled by unchecking "Don't support bridges" under "Print Settings" -> "Support Material". It is recommended to check the resulting g-code from "Plater" -> "Layers", Slic3r may produce support structures that are difficult to remove.
• Slic3r UI settings for temperatures don't seem to do anything, if you want to change them go to "Printer Settings" -> "Custom G-Code" and change the numbers on the lines that say "M190 S110" and "M109 S230".
• Mendel90 has a habit of creating too tall objects. For example one print came out about 125% height while other measures were pretty close to intended. You might be able to compensate by scaling height of your object to 80%. If you find a good solution for this, please write it here or update the settings.
