Frequently Asked Questions

If you continue to encounter filament grinding, even after
increasing the temperature, then the next thing you should do is
decrease the printing speed. By doing this, the extruder motor will
not need to spin as fast, since the filament is extruded over a
longer period of time. The slower rotation of the extruder motor
can help avoid grinding issues. You can adjust this setting by
clicking “Edit Process Settings” and selecting the Speeds tab.
Adjust the “Default Printing Speed,” which controls the speed of
any movements where the extruder is actively extruding plastic.
For example, if you were previously printing at 3600 mm/min (60
mm/s), try decreasing that value by 50% to see if the filament
grinding goes away.
(4) Check for a nozzle clog
If you are still encountering filament grinding after increasing
the temperature and slowing down the print speed, then it’s likely
your nozzle is partially clogged. Please read the Clogged Extruder
section for instructions on how to troubleshoot this issue.
11:Clogged Extruder
Your 3D printer must melt and extrude many kilograms of
plastic over its lifetime. To make things more complicated, all of
this plastic must exit the extruder through a tiny hole that is only
as big as a single grain of sand. Inevitably, there may come a time
