Hello Tmgomes

The K8203 is an update for the K8200 printer using the same hotend as the Vertex K8400 printer :

Searching for “K8400 PETG” get me this post :

So printing PETG seem realy not as simple and safe than printing PLA …

Be safe i mean in the hotend there is a “PTFE TUBE in the ISOLATOR GUIDE”

The standard PETG printing temperature are 210-260 ºC with 60-80 ºC for the bed.

But PTFE begins to degrade above 250°C producing bad flourocarbons vapor( worse if it burn…).

So if you print PETG above 250°C you will have to replace the PTFE TUBE often and a very good ventilation of your room !
and the bed 60°C temps. will be long to achive…

If you find more information or try it, i would be intrested to know the details and result.

Good continuation
