Ironing
left: ironing
right: rectilinear
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 wil remove the inner perimeter on top surface to let the space available for the ironing process.
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...
Also, what is the difference between the three ironing options (plain, triple, and hilbert)?
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.
what is the difference between the three ironing options (plain, triple, and hilbert)?
- plain : use this, the two other are not that useful.
- triple: if some lines are visible, you can try this, it double the smoothing pass.
- hilbert : use hilbert instead of rectilinear for first pass, if rectilinear show some problem.
