Extruder motor pushes filament too fast in a wrong way


Recommended Posts

Posted · Extruder motor pushes filament too fast in a wrong way

Hi all,

I'm a newby of Ultimaker world.

When I print using Netfabb 4.9.1 something strange happens.

The extruder motor starts to push the filament forward too strong and fast, but the heater can't warm up the filament so fast.

So it happens that the filament pushes up the PFA tube and it jumps out of the peek insulator and out of the head too.

Please, can anyone help me finding a solution to this issue?

Is there any setting to do that avoid this wrong behavior?

Thanks in advance
