That would be my guess here. My failures when I accidentally turned off the fan for cooling the extruded element or had an issue with the fan had a similar look (or when I was testing and ran it too high).
Maybe I’ll have to experiment more with my A350 SM2 then. I pretty much consigned it to Laser and CnC use occasionally as after a number of weeks I couldn’t get it dialed in as well as my Ender3 or CR 6SE. I was also having big warping problems even with a wide attached brim and 1st layer warping whenever I went over about a 5 inch by 5 inch area.
Very much in agreement! Even if just to keep the bundles that are typically offered post KS. I can pick up a number at once, but hate wondering if I can build some of the examples shown from KSs without having to search high and low.
