Separate extrusion width setting for inner perimeter loops #1775

Closed Jobii closed 10 years ago

Jobii commented 10 years ago

Hello, I found a strange correlation between nozzle size, first / other layer heigths and extrusion widths, which seems not logical to me, for example layer heigth 0,2mm / nozzle 0,5mm, result in an extrusion width of 1,02mm layer heigth 0,2mm / nozzle 0,3mm, result in an extrusion width of 0,37mm Please see the added table for details. I also wanted to upload the config.ini, but only images are allowed.

I also think that perimeter extrusion width should not be equal to nozzle size, but for example 0.05 - 0.1 mm more than that. Of course lower the perimeter width, the more detail you get. On the other hand print becomes weaker. In vases you get weak walls, and in normal big parts there is increased chance of delamination.

My friend asked me to print an aeroplane wing profile for him from abs. With stock settings I got delam, and with +0.1 mm perimeter width the issue was solved.

Would it make sense to have outer perimeter width and "the rest of the perimeters width"? And then get the best of both worlds.

It's wanted and logical.

But I think your last sentence contains a very nice proposal. I like it.
