Gap in supports
I did paint on supports and looked at the print to find some open areas under 2 of the spots that were in the middle of where I had painted right under the real print. It then bridge infilled. Do bridges come off the print? How did this happen?
Best Answer by Neophyl:
If you are using one of the default print profiles there's a setting called 'Dont Support Bridges' which is enabled by default. That will stop supports being placed under your bridges except for the perimeters. Turn it off and the supports you expected will be generated.

Thank you! I just saw that setting and am thinking what the heck is this for?! This part of the print is parallel to the bed so why would it put bridges there and not other flat spots on the same face?

I would also think that if it is being supported, why would it bridge in the first place? I mean isn't bridging supposed to just help overhangs that aren't supported? Sorry I'm a noob to this whole thing but especially supports.
RE: Gap in supports
A bridge is a flat section that goes between 2 points, ie it’s like a bridge. They aren’t related to overhangs as an overhang isn’t supported at both ends.
Slicer is a bit weird when it comes to them and lots of people don’t like how it does them. It will add supports under the perimeters during slicing and then it will ‘bridge’ between the perimeters so it doesn’t need to put supports under there. With the right circumstances it can actually work well. It is missing a setting for maximum bridge length though so sometimes it can try to bridge stupid long distances
It’s always best to carefully check the preview layer by layer and look at the colour coding though, on every slice really. Good habit to get in to.

Well all in all not too bad, though the bridging did make it difficult to remove the supports in that area. I unchecked that toggle for the time being and I will start to look more closely at the layers in the slicer from now on. Here is a pic of the final print and supports removed. The second pic is the kinda rough leftover from the bridging.
RE: Gap in supports
Ah the pinch model for the outboard from the mini forum.
I’m guessing you have the contact distance for supports on the default of 0.1 ? If you set it to 0.2-0.25 it’s much much easier to remove them.
RE: Gap in supports
@neophyl
Yes the punch part. Lol. I actually had them set at .25 and most of them came off pretty nicely. just those stupid bridges were bad. If it supports under the bridges will they come off easier? Hers a pic of the hole that caused me the problem.
RE: Gap in supports
Probably not, its the bridges sagging down and then fusing to the filament below that usually the cause of them not releasing cleanly.

You're probably right and I sure as heck don't know! ROFL! But, I will keep trying and see just what the heck I can learn. I do appreciate your help a ton. I am enjoying this new hobby!
