Hello… Having issues with printing again. The first layer is always kinda wavey, which seems to ripple throughout the entire print. This is very noticable on larger, flat items… I’m getting very tired of screwing with this. Truth be told, smaller parts that dont have large flat areas don’t seem t…

I feel for you @MooseJuice , 2 steps forward, 2 steps back. Well the easiest thing to start with is the filament. Using an online ellipse area calculator the cross sectional areas of an ellipse that’s 1.74/2.10mm diameter is 2.87mm2, but a 1.75mm circle is 2.40mm2. That would lead to overextrusion o…

[Screenshot_20201110-072339_Chrome] So the line in the red circle looks like a travel path. If your oozing some filament while the tool head moves it tends to leave lines like that. The green circle is somewhere that didn’t finish printing on that layer yet. The waves in the orange circle appear…

For brent, regarding the filament consistency, i cant find a 1 meter span similar let alone 20 feet. However, its generally within .02 from one area to the next. I think… I have about 10 different spools of material and I guess I will open them all now to see if ANY of them are not shit. Unfortuna…

I just googled ellipse area calc and used the first one, seemed to work well enough. Make sure and use the radius and not the diameter like I did hahaha: https://keisan.casio.com/exec/system/1223289167 You could take the area from the calculator above and solve for the circle diameter that’s equiva…

If that is a finished layer that is very odd… seems like a slicer error to me. I say that because of the way that all of those style lines follow the radio’s of some other part. Its like the slicer meant to go back and fill them in, but then didn’t. Having the width just a bit smaller(like you said…

Well, I guess hopefully we can figure it out together over time! I am back on that part, this time with ABS I am trying a concentric pattern on the top layers this time

So I am experimenting a lot to try to resolve this… Alot of it is over extrusion as predicted, but what I don’t understand is if I print a raft, it looks gorgeous. Why would the top of my print look different than the top of a raft? I am going to be looking very closely at the raft settings to try…

That depends on the slicer your using. I know cura applys the “top & bottom” setting to the first and last x layers for any given spot. Not sure why your raft would come out better. If you have a separate top layer flow setting you can try adjusting that?

In addition to what atom said - rafts printing fine but not top surfaces tells me there’s a difference between unconstrained regions (raft) and constrained (top). With a raft you spiral outwards. With a top surface a perimeter is set, and then infilled. With unconstrained regions small amounts of…

Thanks, that is a lot to digest I will briefly add before digging into your suggestions that I have done this with both a 15% infill and 100% infill. The sparce infill creates pillowing, which as you described does gradually become nicer with more layers I think that just the way the layers are pr…
