Allow gcode-modifiers to not split areas.

[CCS86]

2.3.55.2 / Win 10 x64

It seems as though bridge perimeters are not being considered "bridges", and are causing the infill area above to split, with a non-100% above-bridge flow ratio:

Bridge Test.3mf.txt

IMO, "bridges" and "bridging perimeters" should be considered the same for this purpose and not split.

The issue is present on 2.3.55.4.

To reproduce the issue, use over_bridge_flow_ratio != 100%,
and for better visualization use only_one_perimeter_top = 1 with perimeters > 1

2.3.55.4?

I don't see that in releases.

@CCS86 You can find it in the Actions tab

[supermerill]

That's because of the over_bridge_flow_ratio. That is used to compensate a bit the drop from the bridge area.
You can set it to 100% to remove this split when it's not wanted.

mmm. Maybe the problem is that the over_bridge_flow_ratio should also be used over the overhangs ?

@supermerill That might be a good idea, but I think this issues main point it that the over_bridge_flow_ratio line isn't printed continuously with the other lines.

I would tend to say yes to this. But, I only use "overhang perimeters" as "bridge perimeters", with a 100% unsupported requirement.

Maybe "bridge perimeters" and "overhang perimeters" need to be split into discrete categories? Then, bridges are bridges, whether perimeter or internal, and can be combined for these flow overrides.

Also, the "above bridge" flow override seems to do nothing (besides splitting the infill). Flow rate is not increased at all. I can start a new issue if you would like.

[supermerill]

If I remember, it doesn't increase flow rate but creates more overlap, so it extrudes more plastic in the same area.

I think this issue's main point is that the over_bridge_flow_ratio line isn't printed continuously with the other lines.

Yeah, it's better but it's harder to code. I agree I should do that. I also have to use it on multiple layers and not only the one on top because the bridge layer isn't strong enough imo. So any improvements will wait for a complete rework unless it's an easy fix.

I think this issue is still present on the latest release.

over_bridge_flow_ratio: 99%

over_bridge_flow_ratio: 100%

it's something I wanted, that's the whole point of the feature. Use 3 top layers or no over-bridge flow (100%) to don't see it.
This can only go away when modifiers will stop to create split in perimeters & infill.

Yes, but as we now know why this happens, then could we see #914 as a feature request?

[supermerill]

if you want.
there is also #1092 that is the same thing but for perimeters.

Thank you, very kind of you.
