This issue is a very common one for new 3D printer owners, but thankfully, it is also
very easy to resolve! If your extruder is not extruding plastic at the beginning of your print,
there are four possible causes. We will walk through each one below and explain what
settings can be used to solve the problem.
Troubleshooting
1. Extruder was not primed before beginning the print
Most extruders have a bad habit of leaking plastic when they are sitting idle at a high
temperature. The hot plastic inside the nozzle tends to ooze out of the tip, which creates a
void inside the nozzle where the plastic has drained out. This idle oozing can occur at the
beginning of a print when you are first preheating your extruder, and also at the end of the
print while the extruder is slowly cooling. If your extruder has lost some plastic due to oozing,
the next time you try to extrude, it is likely that it will take a few seconds before plastic starts
to come out of the nozzle again. If you are trying to start a print after you nozzle has been
oozing, you may notice the same delayed extrusion. To solve this issue, make sure that you
prime your extruder right before beginning a print so that the nozzle is full of plastic and
ready to extrude. A common way to do this in EasyPrint 3D is by including something called
skirt. The skirt will draw a circle around your part, and in the process, it will prime the
extruder with plastic. If you need extra priming, you can increase the number of skirt outlines
on the in EasyPrint 3D.
