Printing Issue

Hoping someone on here can help identify if this is expected when printing:

I performed 2 prints of the same item, and it did roughly the same thing in the same spot.

The printer is an Creality CR-6 SE printing with PLA - will have to check what printer settings were.

doesnt look like a Z seam, I found with my printer blobs like that were caused by back pressure or the print head having a momentary stutter but i'm using a delta on quite i long bowden tube.I used this video to help me but not sure it would work for you. https://www.youtube.com/watch?v=Hvw3DrVAeTA

Thanks for the link I will take a look. It looks like Cura has relaxed the settings since the video was made, mine comes with:
Max Res: 0.25mm
Max Travel: 0.25mm
Max Dev: 0.025mm

If your Z seam is set to random then that could well be it. Excellent top layer finish by the way.

This was my first thought too.

Thanks for the replies - will test different Z seam settings and see if I can replicate the issue.
