Definitely what @wirlybird said, that printing speed is way too fast, which could explain things if your extruder is unable to keep up the pace. Outline underspeed can probably increase to 80%.

What settings do you have for filament properties (“Other” tab)?

What kind of printer/extruder? What are your retract settings? Are you using coast or wipe?

Is the cr10 a direct drive or Bowden setup? If it is direct drive then retraction is way to high. Should be 1.2-2mm to start and maybe more like 35-40 mm/s.

Extrusion multiplier should be more around 1 for ABS to start and also you need to measure the filament diameter in several places and take the average and enter it also. I find a lot of filament to be closer to 1.7 then 1.75.

You may be under extruding a bunch.

Also with ABS I tend to set an extrusion width a little higher such as .44 to .48 depending. Helps with layer bonding also.

From what google has revealed, the CR10 looks to be a bowden setup. I agree with everything @wirlybird said, especially the filament diameter. I have yet to find a filament that was 1.75 in diameter. Most of the filaments I use tend to be anywhere between 1.65 to 1.71.

You’ll also want to check the tension on the extruder arm. It may be too light and not gripping the filament enough. Also check the extruder gear to see if it needs cleaning.
