Retraction is currently set a 4mm. Nozzle switch retraction is 8mm. So I'll try lowering it and see if it helps.

There is an option for creating a shield but I haven't tried it yet. The model has strings where colors change, but they are easily removed. I'll try it at some point and I'm sure it will help with more complex prints. I have to find it again - can't remember where that option is right now.

I'm trying a custom model now. Having trouble placing the individual parts on the build plate. I though the models would come in with 0 where it was in the original model, and I could just 0 everything out and they would be in the right place, but it doesn't work like that. I went back and set 0 at the COG assuming that would work but it was a waste of time. I finally eye-balled it and hopefully it's close enough for what I'm doing. But I've got to figure out how to make the parts fit together better.
