Flashforge and colorfabb XT filament

[gservers]

Hello.

Need some help.
I bought a flashforge dual extruder 3dprinter.

Now i have a little problem when printing something
The firt copple of layers it prints just great butt after a few layers the filemant dus not extrude any more.
The temp for the xt filament is around 240 and 260 degrees.
I tryed to set the temp higer by 5degrees starting from 240 to 265
Butt still no luck when printing.

What more can i do raise the exstrution speed?

Anny tips are welcome.


And happy holidays.

well i dont have a flashforge. im running a makergear m2 with an e3d so its a bit of a different animal BUT i do print a ton of petg. its actually my main filament i use. i find the xt isnt too much different in settings from abs. i am running mine at 250 but print speed is a little slower with it. i am printing at 3400mm/min. i have printed it though at slightly higher speeds with no issue. it almost sounds like your hot end needs a little cleaning and its tight from old hardened filament cooking in the bore/filament path. i dont have that issue with the e3d because of the ptfe liner and short hot zone but the old hot ends with the peek insulator with the brass tube would do this all the time and would require a clean out after too many switches in plastic types. just a thought.
