Cold pull method

Cold pull method
Problem: One of the extruders is making a clicking noise or not pushing out the
filament?
Cause: It’s most likely clogged or partially clogged. Follow this guide to use the cold pull
method to fix the extruder or just to clean it., This is also recommended when switching
materials.
Setting the temperature
First we need to set the temperature of the extruder to the of the material that’s
currently in it, for this example we are going to use PLA temps or 195°C (383°F) in this
case, for PETG and ABS you might want to go a little higher like 220°C (428°F).
Navigate to the change filament menu.
Set the temperature to the material that’s in the head, so 195°C (383°F) for PLA in this
case, also select the extruder that has the jam

Press the start button.
Filament coming out but with some sputtering or you can hear the motor click? Then it’s
a good idea to do the method described below.
No filament coming out or just a little bit? Try forcing it through by hand and see if
anything comes out of it, if that doesn’t help try this method anyhow if you still can’t get
some material through you might have to change the nozzle.

Set the extruder temp to 90°C (194°F) and the fan to 100%, you can do this in the printer
status menu.
After that navigate to the move menu and turn off the motors so you can freely move the head
around and to make sure the extruder isn’t engaged anymore.

Move the head to the middle of the bed manually so you can reach it better, also take of the top
cover. After that grab the filament with one hand and press in the spring with the other, now pull out
the filament with one swift motion.
Now the filament is out inspect the tip and see if there is any dirt or black particles on it.
Repeat this process until the filament comes out cleanly, after this the machine should be able to
extrude properly again, this method is also useful when switching materials.
