What\u2019s the issue?<\/p>\n\n\n\n
The nozzle is moving, but no filament is deposited on the print bed at the beginning of the printing, or no filament comes out in mid-print which results in printing failure.<\/p>\n\n\n\n
<\/a>Possible causes<\/p>\n\n\n\n —Nozzle Too Close to Print Bed<\/p>\n\n\n\n —Nozzle Not Prime<\/p>\n\n\n\n —Out of Filament<\/p>\n\n\n\n —Snapped Filament<\/p>\n\n\n\n —Grinding Filament<\/p>\n\n\n\n —Nozzle Jammed<\/p>\n\n\n\n —Overheated Extruder Motor<\/p>\n\n\n\n <\/a>Troubleshooting tips<\/strong><\/strong><\/p>\n\n\n\n —Nozzle Too Close to Print Bed<\/p>\n\n\n\n At the beginning of printing, if the nozzle is too close to the build table surface, there will not be enough room for the plastic to come out of the extruder.<\/p>\n\n\n\n Z-Axis Offset<\/p>\n\n\n\n Most printers allow you to make very fine Z-axis offset in the setting. Raise the height of the nozzle slightly, for example, 0.05mm, to get away from the print bed. Be careful not to raise the nozzle too much away from the print bed, or it can cause other issues.<\/p>\n\n\n\n Lower the print bed<\/p>\n\n\n\n If your printer allows, you can lower the print bed away from the nozzle. However, it may require you to re-calibrate and level the print bed.<\/p>\n\n\n\n —Nozzle Not Primed<\/p>\n\n\n\n The extruder may leak plastic when they are sitting idle at a high temperature, which creates a void inside the nozzle. It results in a few seconds delay before the plastic comes out again when you try to start printing.<\/p>\n\n\n\n Include extra skirt outlines<\/p>\n\n\n\n Include something called a skirt, which will draw a circle around your part, and it will prime the extruder with plastic in the process. If you need extra priming, you can increase the number of skirt outlines.<\/p>\n\n\n\n Manually extrude filament<\/p>\n\n\n\n Manually extrude filament using the extrude function of the printer before beginning the print. Then the nozzle is primed.<\/p>\n\n\n\n —Out of Filament<\/p>\n\n\n\n It\u2019s an obvious problem for most printers where the filament spool holder is in full view. However, some printers encase the filament spool, so that the issue is not immediately obvious.<\/p>\n\n\n\n Feed in fresh filament<\/p>\n\n\n\n Check the filament spool and see if there\u2019s any filament left. If not, feed in the fresh filament.<\/p>\n\n\n\n —Snapped Filament<\/p>\n\n\n\n If the filament spool still looks full, check if the filament is snapped. For a direct feed, printer filament is hidden so that the issue is not immediately obvious.<\/p>\n\n\n\n
