gap fill overlap

[ristein]

Describe the bug
It said to report back about that setting:
gap fill overlap does not make much of a change.

To Reproduce
Steps to reproduce the behavior:

1. Compare sliced model with 100% and 0%

>> Project File <<
all settings at standard values (0.2mm NORMAL @ Creality) Printer: Ender 5 plus, direct drive, PEI bed
two parts being sliced: with and without Ironing
TestPart.zip

Expected behavior
Change size of gap fill.

Screenshots
100%:

0%:

printed part trying to tweak (the one with Ironing enabled):

Desktop (please complete the following information):

• OS: Windows
• Version: 2.3.57.2

Additional context
It would be nice to be able to give it more than 100%, as I encounter too little material at Gap fill regions.
How to fill those gaps?

edit:
Parts without Ironing do not have those gaps:
top Parts have Ironing enabled, right parts Layer heigth is .225mm, left parts is .2mm
I find it strange that Ironing is enabled by default.

another thing: Z full step (z_step) is set at 0.04mm for my printer, I was quite confused as the guy in #784 . I guess I can set that to 0.005mm?

another another thing: My part is 0.9mm high. With layer height set to 0.2mm and z_step at 0.005mm there will be 4 layers, but with z_step at .04mm there will be 5 layers.

I guess I can set that to 0.005mm?

you can do what you want. But the 0.4mm is here to ensure the best and consistent layer position.

For an ender3, the full step is 0.04mm and the x16 microstep (imprecise) is 0.0025mm

The ender 5 plus has also screws for bed levelling and maybe the same z cinematic. So it shouldn't be different on the first glance.
If you installed something for auto-bed levelling and/or if you have very precise drivers & strong motors, you should use the microstep precision.

For the gap_fill overlap: i'll check again, but the 100% should mean that there is no further volume to fill. So it can't go higher than 100%

only strange that ironing creates those gaps...

ironing is extremely sensitive to under-extruded areas.
