One of the most important settings is the also the first which you can change. The layer height. Basically, if you want a fancy looking part, set a small layer hight, if you want to print it fast, go higher. But go with a 0.4mm nozzle not above 0,32mm! To make your parts stronger, change the shell settings. Top and Bottom Layer, wall line count. Also change your Infill Settings. Increasing all this, will result in stronger parts.
Speed
So basically, you want you part to finish fast, but not to be ugly. Slow first Layer, a bit slower outer walls, and everything you don´t see, can be printed fast.
Stringing prevention
The keywords are retraction and combing. So first, what is combing? It just prevents retracting, with fast move within the part. So, it creates string, you later can´t see. Because of these fast moves, it only does this within the infill. And what is retraction? This just retracts the filament a bit, so there even can no string happen. After some stringing tests, I concluded, with this printer and this setup, with PLA, these are the best settings at least for me. With other materials, you probably need to this testing all over again yourself. Or you find some proper settings in the internet for another specific material.
Test you settings
When you have set up your profiles, you should test your printer. I have made a little test print you can try to print. You can download it here:
