Horizontal cracks at one side of the print

Hey guys, For the first time, I am encountering issues with a printed object from my vcore 300. For my son, I am printing parts for an Iron Man helmet with Geetech Copper silk PLA. I run it at 205 deg. The print overall looks good, but on one side I am having horizontal cracks / delaminations. I now print the part again, and the cracks haven’t appeared again, BUT I see strong horizontal lines at the same spot. What could that be?

Silk PLA is weird, so you have to print it slower and hotter than normal PLA

yes, but if was the filament.. why does it happen on two prints at the same spot, but nowhere else? but thx for the tip

Check your slicer preview, I bet that area is different than the rest (maybe faster, or different fan amount, etc)

I will, but this object is total symmetrical... so it should be the same on the opposite site. Maybe I try the same file with a non-silk PLA tomorrow just to rule other issues out
