Question about surface artifact on 3D print

[Darkninja]

I have printed out about half of my armor so far and the last 4 prints have been having surface artifacts that only occur on the tops of steep overhangs that have supports under them. It does it at seemingly random spots and was wondering if anybody else has experienced this and could offer any advice.

I am using an original CR-10 with an upgraded bi-metal heat break. I am using Overture PETG and printing at 245° with bed at 80°. The printing speed is 60mm/s for walls, 70mm/s for supports and internal infill, and I believe 25 mm/s for bridges. I am using OrcaSlicer if that makes a difference.

Thanks!

Never mind! I found out it was the scarf joints in OrcaSlicer! The artifacts line up perfectly with where the scarf seams occur in the slicer. Hope this hopes somebody else if they experience this as well!

So I’ve been making some slow progress so far. I’ve got all the pieces printed out so far but might reprint the helmet and make is slightly larger. I’ve been sanding and preparing for priming and painting. I was wondering if anybody has found any foam unfolds for the MK VII neck seal. I’ve been searching around and have seen that people have made them but made no reference of where the template was from. Also, I’m kind of struggling making the ab wrap out of 5mm foam. The different parts don’t want to seem to line up very well. I’m using Monker’s ab wrap unfold. Any help would be appreciated!

I haven't seen a mk VII neck seal unfold either unfortunately. I also make Spidermonkey60 's mk VII ab wrap. What part don't seem to line up?

Here's a post in my build thread that shows how I did the ab wrap:

I want to make a mk 7 suit this summer. I'm going in with a bit of a plan but really I plan on making it up as I go along. This is what I want my spartan to look like when all is said and done: I think the shoulders will be different, maybe the handplates, and different paint job on the gun...
