Rough ABS top layer
Hey guys, this is my first time printing ABS.
Right now I'm kind of struggling with larger top surfaces which are really rough and wavey.
At first, I thought it was a cooling issue, since the first layer above the infill started looking rough. I noticed that it was using the bridging fan speed for that layer, which was way too high. To fix this, I set a separate fan speed of 10% for internal bridges, and that solved the problem with the first layer above the infill being rough. However, after two or three more top layers, I still get this wavy or rough pattern.
Does anyone know what would cause this?
