First let me introduce my self. My name is Joern and I’m from Germany. I have a K8400 for one week and I’m very satisfied with the printer and the results of the black Velleman PLA prints. I’m printing with stock settings (200 degrees Celsius, 90% flow). In my second extruder I have white Velleman PLA and I don’t get the same quality as I have with the black PLA. I lowered the temperature to 185 and increased the Flow Rate to 110%. This helped a litte, but the quality of my prints is far from the black PLA.
Does anyone have similar problems of have PLA/Cure settings for me to solve the problem?
I am using a set of different colors of the Velleman PLA, BLACK, WHITE, GREEN, PINK, etc…
I do not see any difference in the prints.
My temp is around 185C to 195C, depending, if I have hugh areas to fill, where the nozzle cools down more.
Bu tI do not use the provided software, I switched to S3D on the very first day, because I did not like this kind of setting mix and try stuff on different GUIs.
So S3D was my first choice.
To give you some help, you could post some images and the settings
Thanks for your answers. First - my problems where not related to a single extruder or print head. I made a lot of tests and had similar results on both print heads. I printed a small cube with many different settings to find the best value for Temperatur and flow rate for the white PLA. For my it’s 180°C and 90% Flow.
Then I started to print an big skyscraper model. The base was very nice. Look at the fine structure.
But then the first part of the tower was very bad so the print was for the trash can. I could easily break it from the printed basement. Have someone has an idea why the print suddenly goes so bad?

This kind of thing happens when the filament flow is irregular : either it gets stuck in the spool (entanglement) or the diameter of the filament vary too much.
Third possibility : temperature drop during print. The filament is more viscous and fewer is extruded.
