![]() Please look into: "What are main differences between rafts, skirts and brims? It also shows fairly fast if the bed is unleveled as a whole or if the bed is greasy. The function of the skirt is similar as described for the straight prime line, but it has additional effects that can be wanted. The lines at distance from the print object is called the "skirt", the skirt is an option found under the "Build Plate Adhesion" options in your slicer. Further information can be found in Writing G-code : swiping at start of print Equidistant line = Skirt ![]() Note that this straight prime line is not a standard option in a custom profile of Cura, so this was part of the Ender-3 Preset you imported or possibly you have copied a starting G-code that includes this prime line.Ī typical set of G-code lines to create a prime/purge/intro line is found in your start G-code and could look similar to:Īfter slicing your object, you will find such lines in the generated G-code file, but they are not displayed in the preview. Furthermore, a prime line print routine will catch errant nozzle ooze, test extrusion (it is the first indication if the nozzle to bed distance is correct if not you can abort with minimal material loss) and perform a final wipe action to avoid stringing between the prime line and start of the print. This straight line is called priming line, purge line or intro line, and is typically (but not necessarily) printed outside or at the edge of the bed area. The straight line on the left is typically used to prime the printer nozzle to get the filament flow starting, this is typically seen in PrusaSlicer (Prusa's fork of Open Source toolpath generator for 3D printers Slic3r). in OctoPrint print server it is possible to execute G-code before the print starts. If the printer is printing, it is instructed to do so by the G-code file unless you are printing through an external software program that has extra G-code to print before your print starts.
