No First Layer Extrusion Multiplier (aka No "real" first layer adhesion assistance) /* TEARS POURING DOWN FACE #346
Comments
Hello, raft is coming and there's already an issue for that here on GitHub. First layer extrusion was discussed, and it doesn't make much sense because given that first layer is solid you can't stuff more volume in it than 100%. First layer height ratio is not intended to help with adhesion, it serves other purposes. The settings you can tune to increase your adhesion are:

Fair enough. I take it that the First Level Height Ratio is intended to help with non-level/non-flat beds... Because those problems cause first layer adhesion problems... ;) I guess in my own mind, it is potato, potatoe... Except the current setup in slic3r forces you to sacrifice layers of the object for that adhesion... At any rate, I am super excited to hear you are working on the raft. A raft solves all of these problems! |
If you set the first layer height really low you can print really close to the bed which does squish the layer but does not change the size because its only a fraction of a fraction. |
You are spot on :) I have been doing exactly that. |
Hi,
I would like to be able to dial up the amount of extrusion for the first layer. This will help adhesion on the first layer.
Simply increasing layer height on the first layer (while semi helpful) is not really a GREAT way to help adhesion; Dialing up extrusion on the first layer is!
I guess I can to this manually in the G-Code... But yuck.
This problem is compounded by the lack of any raft support what so ever :(
No first layer extrusion multiplier -> adhesion trouble -> corners curl like it is going out of style
These two problems are near deal killers! Yes, I have gotten great prints with your awesome program; the fan control is awesome too!... But the lack of first layer adhesion options, and the lack of a raft make many (common) types of prints ugly or impossible.
These two features would seem easy to implement (simple versions of them at least).
Please consider unlocking Slic3r''s potential by adding a first layer extrusion multiplier and raft support!
P.S. Thanks for honeycomb infill and auto arrange!
