Diagonal scars V
V. Z-Lift
Filament is not the only problem that can cause this issue. If the head does not rise high enough from the print surface, then the nozzle itself may cause a scratch when moving from one layer to another. On older printers, you will need to recalibrate if Z-lift or Z-hop settings are not available, otherwise increase Z-Hop or Z-Lift in 0.25 mm increments.
