<p>I've recently purchased Creality Ender 3 V2. When I print PLA, I face no issue at all but while printing PETG, the nozzle keeps clogging after the second or third layer.

What happens when you print with retraction off?

I've not tried with retraction off.

With PETG I run the nozzle at 250 °C, and all my fans at 100%.  I even added more fans to the enclosure.

I've recently purchased Creality Ender 3 V2. When I print PLA, I face no issue at all but while printing PETG, the nozzle keeps clogging after the second or third layer. I even tried printing PETG by keeping the fan off for all the layers but with no success. The recommended nozzle temperature is 220 °C - 250 °C and the heated bed temperature is 60 °C - 80 °C by the filament manufacturer. For better adhesion, I'm using a thin layer of glue stick for the bed. Due to the unavailability of a Capricorn tube in my city, I've not upgraded the stock PTFE tube yet.

My current print settings in Prusaslicer are as follows:

* Filament: Generic PETG (modified)

Temperature:

* Nozzle: first layer 235 °C, other layers 230 °C.
* Bed: First layer 65 °C, other layers 60 °C.

Fan:

* Disable fan for the first: 3 layers.
* Fan speed: min 20 %, max 50 %
* Bridge fan speed: 100 %

Retraction:

* Length: 3 mm
* Retraction Speed: 30 mm/s.
