The ironing is a new top fill pattern. It combine two rectilinear path: a first coarse one at 90% flow and a second fine one with 10% flow ratio.
To have a nice ironing surface without "holes">
For a better finish, you can also use "only 1 perimeter on top layers", it will remove the inner perimeter on top surface to let the space available for the ironing process.
note: It's (imo) mandatory to have a nozzle with a flat bottom to be able to "flatten" the top surface. This function has been developed with a E3Dv6 nozzle.
Q:
Another quick question about ironing: What does this mean?
To have a nice ironing surface without "holes"> a ironing hole you must have the previous layer at the correct height. Solid layer over bridged (nothing or sparse infill under it) ones can be a bit too low. Up the "over-bridge flow ratio" to recover the correct height. A good value for it is between 1.15 and 1.3.
I don't really understand what it means by the right layer height...
A:
It means that if you have a bit of under-extrusion at a top layer, it will be very visible as the process can't smooth the top layer if there are not enough plastic. Under-extrusion at top is often due to the first top solid layer dropping a bit because the sparse infill can't support it enough. Solution is to increase the over-bridge flow ratio setting.
right layer height
The previous solid layer has lay down enough plastic to fill his height.
