[catalintucureanu]

Cura Version

5.9.0-beta.1

Operating System

Linux

Printer

Creality Ender 3v2

Reproduction steps

Add a simple cylinder, activate Spiralize Outer Contour on a generic profile, slice. Preview sliced part.

Actual results

Z seam is visible in preview with Spiralize Outer Contour activated. Actual printed part also shows z-seam. Same part sliced in 5.8.0 shows up fine (z-seams only on bottom layers and final layer).

Expected results

No z-seam with Spiralize Outer Contour activated.

Thanks for the report.
I can duplicate this.

I wonder if "Scarf Z-seam" might have broken Spiralize?
@HellAholic here is one for you.

Thanks @GregValiant & @catalintucureanu
Not sure what happened with the list of known issues, I can't find them on the github release notes or the change log.
From the top of my head, here are some of the things on the board we're working on (known issues):

• Coasting + Scarf seam -> Creates double seam locations
• Coasting -> Z is set to 0.00 on seam location
• Surface only mode + Scarf seam -> Does not generate scarf seam
• Spiralize outer contour -> Same as you mentioned above.
• ... (out of memory)

Keep the reports coming, appreciate it.

Observations:

1. "Experimental" is the correct word and has been used properly.
2. The breakage list is turning into a laundry list.

That was quick. Thank you.

Im having difficulty with spiralise in 5.9. I was previously using 5.3.1 and spiraise in Normal mode would do the extra run around the top finish the spiral off nicely. In 5.9 it stops very briefly on the top where the preview shows start/stop just as in the images above, and puts a nasty pip in the print.

5.3.1 didn't do this and so in 5.9 this is broken for me. For my print its important that it makes no stops otherwise the print is ruined.

5.3.1:

Same settings in 5.9:
