The surface deformity you are referring to is called "elephant foot," which typically occurs when the first layer of your print is squished too much against the build plate. To avoid this, you can try the following steps:
Level your build plate: Ensure that your build plate is properly leveled so that the nozzle-to-bed distance is accurate.
Adjust your initial layer height: Increase the initial layer height slightly to reduce the pressure on the first layer. Experiment with different heights until you achieve the desired results.
Use a raft or brim: Adding a raft or brim to your print can help distribute the pressure evenly, reducing the chances of elephant foot.
Decrease print bed temperature: If you are using a heated bed, try lowering the temperature slightly. This can help reduce the amount of material squishing during the first layer.
Use a different slicing software: Different slicing software may produce different results, so you can try using a different one ...
