I am trying to print this head using simplify3d but facing problems with stringing and zits. Its quite surprising that stringing doesnt happen within the model but only between support structure and the model. Therefore, it is not a problem of temperature but of retraction. When i observed the printing process, the string happens between the support structure and the skin of the model. The string can be easily removed but leaves a scar or a mark on the model.
The second problem is that of zits. When i dont use start perimeter at random points the zits occur in a straight line but when i randomize starting points small blobs appear all over the model. What parameter should i be controlling for this.
