RRF 2.03 pressure advance causes 20% overextrusion
-
@mendenmh yes, could just model that and limit acceleration to stay within torque limits.
-
Getting endless "connection reset by peer" upload failures when trying to upload gcode to RRF 3.1.1. Not sure if the issue is with my network or RRF 3.1.1.
-
Is your DWC version also at 3.1.1?
Post the result of M122?

Hard enough to get PrusaSlicer to generate gcode without 20% more extrusion than the volume of the STL in the first place
Ahem: https://github.com/n8bot/PrusaSlicer/tree/n8_precision_minus_infill_support
This fork of PS 2.3.0-alpha alleviates inconsistent extrusion rate, among a few other things. I think you'll like it. Build that n8_precision_minus_infill_support branch.

Check the General > Settings tab in DWC to see what version it's at.
M122 looks ok.

@bot I tried to build PrusaSlicer before and gave up because of ridiculously huge numbers of dependencies on cutting edge versions of everything.
-
@bot do you think you could build the linux .appimage for that and send it to me?
-
@jschall I do not have access to a linux machine, and have never built an app image... I've only built this on windows.
However, I found the SuperSlicer (fork of PS) build instructions fantastic.
https://github.com/supermerill/SuperSlicer/blob/master/doc/How to build - Linux et al.md
Give that a shot.

That's just identical to the PrusaSlicer build instructions.
Hmm, even a windows build would be fine. Can run it under a VM.
-
@jschall here's the windows build I run day-to-day:
https://github.com/n8bot/PrusaSlicer/releases/tag/v2.3.0-alpha0-n8pmis
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?
-
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... -
@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.
-
@bot
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. -

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.
-
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.
