Have any of you tested bridging at all? I am going to be printing an internal slot that is 4.5mm by 1.5mm wide (1.5 will be what needs to be bridged) and I was wondering if you all thought this would work?
If you set fan on 80-100% bridge should be printed 
I have bridged up too 20-30mm, look at this link: http://forum.zortrax.com/index.php?/topic/291-m200-fan-shroud/?p=10375
So consensus is just to run fan near full speed and ill be fine?
I would be surprised if you needed any special (higher) fan settings to bridge 1.5mm.
You may want to turn part 45 degrees.. Check how the first layer is in the tool path.. Read this.. http://forum.zortrax.com/index.php?/topic/296-bridging-with-zortrax/?hl=bridging
