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?
