Where do these little dabs come from? And how can I make them less noticeable?
Every entry point in each layer will cause a blob. You can make it less obvious if you arrange the entry points in a column, popularly referred to as a "seam". Click into the "Slice" menu of CraftWare and look below the Advanced tab; here you will see a section entitled "entry point weights". There are many factors that will determine the placement of these starting points, but for the sake of a quick trick, change the "Proper corner angle" and the "Near to previous point" both to the same value ("10" is a safe bet -think "close to 10"). By-the-way, the values range from -10 to 10. Now, look up a little further to "Perimeter gap": remember the value that is there to start or the value you wish to have when printing and then make a temporary change to a greater value so that you will be able to easily pick out the bulb places on your virtual model *ALWAYS CHANGE THIS VALUE BACK TO THE ORIGINAL BEFORE YOU PRINT OR ELSE YOU WITH GET LITTLE HOLES IN YOUR PRINT*. The "Source Direction" selector will help to better place what side of your print you want your starting points situated.
