What is the best settings for "Horizontal offset from part". The default was set at .3 but it results in supports that are difficult to remove. When I set to .4 the print messes up and I get goobers. Also, what is best "support structure under-speed", the default is 80%, but couldn't you print at 200% and still achieve a good support?
