Hi in uber going to my tennis teaching job. I got 4 rolls of the Sunlu petg-hs filament. Set up a profile. Temp set in profile at 250-270. So i could print at luacrist spelling mode. Calibrated filament abd all that stuff. Started my gist print with that filament. I noticed that the temp read 220c low for vasic petg. Do you think my X1C is that smart that it dropped the temp down because of the sctual print speed of the current layer? This filament can be printed between 215c abd 270c depending on the printer speed. If it is that inteligent then that is pretty darn anazing.
I’m not familiar with the exact behaviours of the X1, but there are specific settings for both speed/acceleration and temperature for the first layer(s) of printing, and default first layer setting for Generic PETG HF is 220, so perhaps it is simply that?
I wonder if something is not working. I checked the temp. After Slicing my print and it shows that this is going to print the whole object at 220C. In “my Book” the temperature is way to low. If I switch to the Generic Petg profile it prints it at 255c. I tried changing the profile to the Bambu Petg-HF profiles and sliced my part it prints it at 230C. My first small part printed OK at 220c. The speed is lower so the filament can print at this low temperature. As stated above I setup a new profile for the Sunlu-HS filament. I just tried to set the temp. In the profile to a Min or 250 max at 270c but it still wants to print it at 220c. It seems like it is not reading the temp setting in the Sunlu profile. I am getting crumbly filament. This can be due to moisture or temperature. But what is the problem? I have printed a number of big part with MatterHacker Build Series Petg filament with the a custom profile based on the Generic Petg profile these print came out perfect.
Oh, I see that the actual print temp was set to 220 in my profile. I thought that Bambu lab had intelligent AI that could pic or alter the temp based on temp and type of filament etc. I guess not. Still learning. With the help of Google Gemini.

YES, I am about 5% into my big reprint and set the values to 230c first layer and 250c for all other layers I just up from 100% to 166% speed and 250c is the recommended value for this filament. Looks better so far. The print after slicing varies in speed from ruffly 86mm/s to around 150mm/s. In standard 100% mode. Up that value by 1.66% to get the ludercrist (spelling) mode. So, it also remains that if my prints are probably not going to bring over 215-220. At 250c then I wonder if there is much advantage to using the Sunlu-HS filament over Sunlu Basic PETG.
Temperature and filament characteristics are all tuned by the profile you pick… I think the “AI” stuff is primarily geared towards preventing spaghetti monsters, first layer adhesion and filament flow.
