Hi，thanks your photo.
This should be caused by insufficient extrusion.
You can use a measuring caliper to test its diameter to ensure that the diameter of the material is consistent with the packaging logo.
If the material diameter is consistent with the mark, but there is still a problem of insufficient extrusion material, then the extrusion speed needs to be adjusted.
ABS materials usually have an extrusion volume of 109%, while PLA is 105%. If everything is normal and the amount of squeezing is too much, then reduce the amount of squeezing accordingly to keep the printing at a normal level.
Hope to help you.
