I am using the default retraction settings for a SD3. I was able to fix the fatter bottom layers by adjusting my bed height. On 1mm prints the strands are much better than at 3mm.

In theory the hotter the plastic is the better it bonds but going too hot makes it runny. I usually print the first layer at 195 then go down to 185 for the rest of the layers.

As for the strings thats a retraction issue. What are you using for retraction settings?

I just got my SD3 yesterday and so far things have been pretty good. I do have a quick few questions that I think that someone here can easily answer.

1. The first few layers are a little wider than the rest (very minimal). I'm trying to print something that is pretty precise and was wondering if there is anything I can do to fix this. Would making my temperature hotter or cooler help or could it be that the z axis is slightly out of alignment.

2. From some of the prints that I have done (and others that I have seen on here) there have been a few strands of plastic that go from one point to another. What is the best thing that can be done to minimize these? Would this be a temperature issue, a retraction issue, or both?

Thanks
