He advised to do this:

  • preferences (ctrl+P) → activate developer settings → Quality →Advanced → First Layer Flow Ratio: 1.04

I activated dev settings but only see Initial layer flow ratio. Thats the same??

Will this close the gap? Any other ideas?

Thanks!

  • YES = It will flow more filament on first layer only it will help

This setting will override the global setting for flowrate in filament settings?

Thanks!

Only the first layer will get changed with more flow; all other layers above it will be your master flow ratio setting.

But how this modifier works. If my flow ratio in filament settings is set to 0.95 and I will change the Advance first layer flow ratio to 1.05, will I get 0.95*1.05, or maybe will I just get 1.05?

The wiki states that the flow ration is calculated by entered value. Meaning you will get 0.95*1,05 and not 1.05.

The actual flow ratio is calculated by multiplying the original flow ratio by this factor.
