Under extrusion on higher layer height

Post by jussi »

Hello,

I'm using v2 a 0.4.4 version. I tweaked flow 0.95 to get nice top surface and no messy anywhere. But that setting somehow change with layer height. If I print max. 0.25 I get good results but higher than that under extrusion? I'm using ASA and printer is prusa mk2 with volcano hotend 0.6 nozzle. Left is with 035 settings and right ones with 025 settings. Huge difference.
Other thing I noticed is that 1st layer is almost every time something else than set.

Check out the Settings/Printer/Hardware/Loop Solid Infill Overlap (slider setting).

Needs to be around 1.7

It's 0.75, is that somehow changed from 1.6 to v2? 025 layer height it prints fine with that and there is gap between lines also

The range was changed from 0 to 1 in V1.6 to 0 to 2 in V2.

I suppose in theory that is correct ;)

Slice a model or two, look at the paths on the top layer and have the "3D" check box ticked. You will see what you need. Don't take any notice of the first layer; that seems to work differently.

Thank you very much for the clarification Peter! Doesn't this uber important setting seem kinda buried in the Hardware tab? Isn't it more like a Style setting? 1.75 s/b suggested in the tool tip.
