13mm bridge, PLA @ 225C = FAIL

[Geoff]

Trying to print a simple tray for an Arduino Uno. The wall opening for USB measures 13mm across. The bridge at this location is not pretty due to multiple sagging extrusions. The support option in slic3r 0.9.9 was not effective as it only supported a fraction of the 2.1mm wall thickness, leaving the remaining portion to sag.

I am currently operating with the default slic3r config provided by Maker Farm (Prusa 10" i3v) which has the PLA extrusion temp set for 225C along with a bed temp of 70C.

I've done just a little research and this has led me to consider lowering the extrusion temp to ~200C. Good idea, or will that cause problems in the 0.4mm Hexagon hot end? Using 3mm PLA.

Don't be afraid to play with things, the worst you will get is some clicking...

The bridging in Slicer is in a section on its own in print settings under Speed, have you tried changing the actual bridging speed?
