Concentric setting explained (Edit Image Function)
You'll find this setting in Edit Image.
In terms of functionality, the concentric setting keeps printing the same shape smaller and smaller to create filled shapes. Generally speaking, having the concentric setting on while using larger nozzle sizes can give better print results.
To access the Concentric setting, edit the shape. In the edit image screen, you'll see a toggle for a Concentric setting. The fill function must be activated in order to control the concentric settings:
You'll see a drop-down option that is available with the concentric settings on. This allows you to control printing shapes from a full fill (Auto), to a certain number of "walls". You can make between 5 walls and 1 wall.
If your print seems to have too many stops or jumps while printing, try de-activating the concentric setting or adjust the Jump Settings: Minimum Hold Distance.
In the example below, we are printing with a 4.0 nozzle: the shapes on top have the Concentric setting off, and the shapes on the bottom have the Concentric setting on:
You can see that in the bottom shapes, where the concentric setting is on, the same exact shape is printing small and smaller as seen when looking from the outer edge of the print towards the center of the print. Whereas the top shapes, where the concentric setting is off, has a different print path.
You will not see Concentric setting changes reflected in the Edit Image screen. For example, in the edit image screen below, it looks like the circle has a full fill, despite having concentric on and set to 2 in the dropdown.
However, when you go to print preview, you'll get a realistic view of the actual print.
