Hello all, During a recent few prints, I've been noticing defects on the top layer. The rest of the print goes absolutely fine, but there's these oddities on the top and I've got absolutely no idea what could be causing it. I've checked the troubleshooting guide very thoroughly and noticed the surface scratching there, but this is still a different issue I believe. Can anyone help point me in the right direction to fix this? I've been thinking filament defects or thickness variation, but it would be a strange coincidence to have 7 defects on the top layer, but none on any of the lower layer top surfaces which cover at least as much area. Thank you for your time.
