I have been using my cousins 3D printer, which is a DaVinci 1.0. I am used to using a Makerbot replicator. One thing i notice is that the layers are very much more noticeable on the DaVinci. Is this normal, or is there a way to calibrate it so that prints can look more refined? I would imagine there is a way to change the layer height but I can't seem to figure out how to make the prints look better.
