New to 3D Printing and need some help.

[Roxy]

I found that if I slow the print speed down I get a much worse bridge. I had to print at a speed of 200% to get it clean. I also used a fan. You could actually see the filament sag a bit and then pull up and tight as it cooled. The "sag to pull" occurred in about 1/2 second. It was interesting to watch.

This is the opposite of what I always thought was true. I've been having trouble with bridges lately. I'm messing with speed settings this morning using that ThingiVerse file you posted.

UPDATE: For my printer, high speed bridging fails horribly. I'm going to keep playing with it, but Bridge Speeds of 20mm/s with a filament rate of .9 works on all the different size bridges. The biggest flaw is the gap in the center of some of the bridges. That almost looks like a Slicer issue???
