Hi,
gotta say I haven’t read much about this subject but I’ve been having alot of dificulties with this…
Lowering temperatures or increasing?
Speeds?
Any pointer is appreciated…

Any more details about the issues you’re having? What filament? Temperatures, speed, etc?
Sorry for late reply…too much work and not having much time for anything else…
As for setting basically im using the Simplify3D settings provided in another thread here with just some “minor” tweaks in layer heights and support. Yes, using Simplify for now. IMO it allows more control and is more user friendly than Repetier or Cura. I know that “more control” also can mean more probability to mess up…
My phone isn’t much for night pics or closeups so I can’t take some pics of my prints for now.
Resuming:
Printing Sharkz
Using standard Simplify3D setting from viewtopic.php?f=64&t=15257:
- PLA at 190º or 185º
- Layer height 0.2025 ( need an explanation on this value…why not 0.2? )
- No support
- Infill 25% first try, 5% second try. ( Don’t think this will have much impact on bridging issue I think… )
When I printed with 190º the extruded filament just hanged down form the sides…So I thought with less temperature it would allow the plastic to cooldown faster and not “drop down”, so tried again with 185º and same result.
The thing that bothers me the most is that in one of my first prints http://www.thingiverse.com/thing:355110 came out perfect…don’t recall settings, I know that it was done with Repetier and 25% infill and 190º or 195º…
My question about pointers is if it is need anything else…any setting I might be overlooking…I don’t know…any pointer 
Regards

Are you printing the Sharkz thing flat on its side? Should bridge that internal bit ok.
I’ve done fairly big bridges with Cura settings ok, not sure about Simplify. I’ll try it on mine tonight. Think Slic3r offers you more a bit more flexibility than Cura wrt to bridging, but I’ve never needed to resort to switching slicers so far.
Yeap…flatout on it’s side. Tomorrow in gonna retry with Repetier.
In Simplify you got an option to tweak speeds, extrusion, etc when briding…
I think I better remain on Repetier for now since it’s the “Official” software.
Tiny question:
For better bridge results should I increase temperature or decrease?
On another note…This came out with 190º and 0.2layer
I just printed sharkz using S3D and it worked out really well, apart from the raft.
First I ran the Bridge torture test http://www.thingiverse.com/thing:12925 & reduced ‘Bridging speed multiplier’ to 50%. I left the unsupported area threshold at 50mm2, and it came out very well at the first attempt - hardly any stringing and the circle in the middle was well-formed.
For Sharkz I lowered ‘Unsupported area threshold’ to 25mm2 as the bridge area seemed quite small. I missed both bridges being printed so I don’t know if it slowed down.
After removing some of the raft the jawz moved easily - I thought I would have to clean out some stringing but it wasn’t necessary.
Regarding the raft - is it really needed, and if so why? I’ve never used raft before, what’s the easiest way to remove it?
I’m using the Velleman PLA (neutral), and I have the temperature at 190 for the 1st 3 layers and 180 after.
I’m also trying the Zebra plate for the first time and it is really good - sticks well and so far easy to remove by flexing the plate.
I just printed the Sharks thing too, and it was perfect.
No bridging issues at all.
I’ll add photos later.
Did you use raft as suggested in thingiverse?
I’m printing another one now with just brim to see how it works. Bridging part is finished and it looks good again

Used Repetier with default settings and it almost came out perfect…some strings “broke out”
Not sure if I used anything specific with regard to bridging, but the shark just popped off the bed and worked first time.
yeah…mine too, popped nicely and worked but still got some stringing. Now I know it’s parameters 
Got this out of printer after some fiddling with the Igus bearing…too much slack on X…next will be Y. Maybe next weekend…if I’m feeling up for desassembling printer again 
Or i’ll remake the XY bearing clamp to acomodate brass bushings.
These are my main probs…too much wiring.

You maybe print it 0.1 mm ?
For printing 0.2, for avoiding bridging with pieces like your shark, I encrease top en botton thinkness (in cura setting) to something like 0.6. Defaut is 0.3, so for 0.1 print, he made 3 top layers, but in 0.2 only two and hole remain in the top surface. With 3 top layers, you could print shark at 10% infill and have a perfect result.
