The reason for scorch moarks is directly due to the hotend heat and inadequate fan cooling. Check your print file for the fan settings. If it is on “auto” the uncheck it and set the fan to 100% and see how your next print come out. I saw some minor scorching taking ng lace and by simply blowing air onto the print for a minute the scorce went away. You can find better fan ducts on thingiverse you can print. There is even a dual duct that requires you install another fan but it would breatly i,prove the quality of your prints.
The problem is with Z-Suite. When preparing a print, the rafting geometry will also add debris to certain corners of your part. The burn marks are always concentrated around 1-2 particular areas, whether it’s a flat surface, or a corner. If the burn marks were randomly placed, then it would make sense there would be something wrong with the extruder, but that’s not the case. Upload the burned images too for our inspection.
Try printing in Z-HIPS, the finish quality will typically hide the burned areas.
