For the first 2 weeks after receiving my SD 3 all went  well right out the box( see picture). Most prints turned out pretty well. Then the hotend failed .yea  got new one and nothing has been good since.I did changed to the mk4 , maybe go back to jigsaw? I dont know why it should matter tho.

You'll have to help us out by explaining what is going wrong now.  What do you mean by nothing is good.  Pictures always help.

Re: printing woes

Let me claify that, this pic about the only thing that prints right. I am  try to print a simple logo  that I created in Google sketchup, letters on a small block.The bottle print looks about perfect but logo prints are coming out all stringy. Could it be the way the stl file is saved?I got the bottle off Thingiverse.Both were priinted at .1mm,no pic of logo,its so bad

Re: printing woes

This is two distinct meshes according to the STL.  The final object contains intersecting facets all over the place and when I slice it with slic3r I don't even get the block.  Note that I'm slicing it on it's back with all parts laying down as originally set up in the STL.  The upright version looks fine.  It seems that slic3r recognizes the joins and fixes it so that it will slice correctly, but I'm not sure about other slicers.

The stringing could be retraction related as the letters are close together, but I can't be sure.
