I had support turned on (which you can see in the background *is* being provided for an overhang that hasn't yet printed), but these two openings in the front needed it, and they didn't get it. You can see the sag. What should I have done so that they too would have been supported?
I'm using PETG using a volcano 0.8mm nozzle at a 0.2mm layer height, 0.96mm width, on a Prusa I3 MK3. I'm running the current version of Simplify3D.
This is the object being printed: https://www.thingiverse.com/thing:2812350
S3D thinks that your printer can bridge those openings. There are a couple of ways that you can deal with this.
1) Manually add a couple of support columns so your bridging will work to cross those open spaces.
2) Do some combination of [override fan speed to 100% for bridging/increase bridging speed/reduce bridging flow]
I forget what tabs these settings are: speed, other, advanced. In one or more of those pages.
3) Change your support settings to reduce the span that S3D will call a bridge.
