RRF 2.03 pressure advance causes 20% overextrusion

It's almost the latest PS master branch, but the latest changes they made to the master branch aren't useful so those aren't included yet. (waiting for the seam painter to actually work, not just paint meaninglessly)

@bot What's the difference between that and the n8_precision_minus_infill_support branch?

bot

That release is the n8_precision_minus_infill_support branch.

I copied and pasted the description from a previous release hastily, so it might have said the wrong thing.

The previous releases work fine, too, but this one enables better support placement (PS ignores some "thin" support regions which prevents some support from appearing) and also prevents the solid infill from "auto-adjusting" the width by ~1 micron, which was annoying in some cases but not important to "fix."

There are other releases there, too.

The two main things I think you'll like are the resolution change, and the decimal precision changes. Fixes extrusion rate problems.

Edit: Also, you might need some .DLLs from MS Visual Studio redistributable. Let me know if/which ones you need I can send them too.

@bot ah ok.
It is complaining about vcruntime140_1.dll, but I've already installed the visual c++ 2015 redistributable...

bot

@jschall Yup, that's the one. See this post: https://forum.duet3d.com/post/170901

I uploaded the .dll for someone previously, but it's named as .stl. just rename it .dll and put it in the prusaslicer folder or wherever.

I also just updated the release to include that .dll. I hope that doesn't break a EULA. oh well.

Got it running. Doesn't work in VirtualBox anyway because no opengl 2.0+ support. So, I ran it in WINE and it works fine. Extrusion amount looks about right.

@bot I tried to build PrusaSlicer before and gave up because of ridiculously huge numbers of dependencies on cutting edge versions of everything.

They have "noob guide" now. It's basically how it should be built, not really for noobs, but for anyone with a little bit of sanity left. I'm wondering why they even bother with having a guide; the steps can be semi-easily compressed into a batch file. Maybe they take pride in memorizing random things...

Good to see "Detect thin walls" still sucks just as much as ever.

bot

Haha. Yeah. There's lots of "fun" things going on in PrusaSlicer. There definitely needs to be a huge refactoring, IMO. Many features need to be removed, or re-considered in the context of other newer features.

Still better than Cura.

jschall

@Phaedrux Really? Cura seems to do way way better than PrusaSlicer when slicing things with thin walls. Also it has support for coasting which is super important on my ender3 v2s that don't frigging work with linear advance...

I just hate Cura's interface. Hard to be worse.

oliof

Superslicer has something like coasting iirc

Phaedrux

@jschall I find Cura falls apart faster than super Slicer on thin walls. In Cura you're forced to use 2 walls. The master build of Cura has the option of trying to replace one of those wall passes with a travel move, but it rarely seems to work well. At least the gap fill in Slic3r has a lot more leeway with regards to wall thickness. It's true that on the really thin side the walls just don't get extruded at all, but it seems to be a lot more forgiving. Cura will print the thin walls but it's usually well over extruded.

@jschall
have you watched https://www.youtube.com/watch?v=7W5pPm0lZDE? it mentions the problems with the titans.

jschall

@Phaedrux Cura has something called "compensate flow" and I think it reduces the flow on one of the two walls so that the total extrusion volume is correct for the wall thickness.
