So I was printing a low poly bunny and all of a sudden the new layers didn't adhere to the other layers. I don't think it was printing an overhang.
I have an ender 3 pro which I use together with Cura. I print in PLA at 200 °C. The print bed is set to 60 °C. I use a print cooling fan at 100 %. The layer height I set to 0.2 mm, the line width 0.4 mm from the 0.4 mm nozzle. The Printing Speed is set to 30 mm/s for outer walls, 60 mm/s for inner walls, and 60 mm/s for infill. My retraction is 6.5 mm
