Blobbing/Illegible Rear "3DBenchy" Text Using Klipper and Cura 5.4.0

[BigWampa1989]

Cura Version

5.4.0

Operating System

Windows 10 - Klipper

Printer

Creality Ender 3

Reproduction steps

Hello, I recently had a ticket open (#15746) (see also ticket # 14811) for 5.3 which was closed as resolved under 5.4. It involved blobbing issues when using Klipper with Cura 5.3.

I downloaded 5.4.0 and it did in fact fix the blobbing issue. However, the #3D Benchy script on the back of the boat printed in what appeared to just be numerous blobs. I printed another benchy with the same slicer settings and printer with Cura 5.2.1 and the text was completely formed and legible. I went and looked at the benchies that suffered from the blobbing issues from 5.3.0 and the pattern of the issue appears very similar. I attached the GCode for the 5.4 and 5.2.1 versions as well as pictures. I tried my best to capture it on camera but it is hard to capture just how different they are with the color I used.

Actual results

Illegible 3DBenchy back text.

Expected results

Legible 3DBenchy back text.

Attached is the 3d Benchy with the printing settings. I used the same settings in 5.2.1 and it printed fine. I did not change any of the Resolution settings but they were also the same between both versions for the test prints.

Hi, is their any update on this issue?

Hey @BigWampa1989,

Quick update from our side 👋

There are two improvements done in this area for the upcoming Cura release.
First, we solved a bug that caused shifted lines if the resolution was relatively high #15949
Secondly, we introduced new settings for fluid motion printers here #16444

When I disable these settings to smooth the motion I see that the texture shows up better.
If I make the slicing tolerance exclusive, the back of your Benchy looks like this with the 0.2 layer height.

I hope this helps 😇
