On the red piece I see that at around layer 15 there was a slight problem, at the visible defect the problem was major, and above the major problem there is another layer that shows the minor defect again.
Since they don't appear to be at regular intervals (Z binding or junk on the Z wheels or something else mechanical) then it would appear that something is intermittently affecting the extrusion. The Enders (I have a 3 Pro) and CR-10's share the same model hot ends and it's often a partial clog at the bottom of the bowden tube where it is supposed to provide a seal against the top of the nozzle. If a gap develops there (and it will over time) then longish retractions can pull molten material into the gap between the tube and the nozzle end. That material in the gap can cause a partial blockage resultant in intermittent flow.
Fixing the problem requires warming up the hot end, taking the nozzle off, pulling out the bowden tube, passing a piece of correctly sized wire (I found a coat hanger that worked) through the hot end to push out the plug of plastic, and trimming off 5 or 6mm of the bowden tube. The cut on the end of the bowden tube needs to be as exactly square as you can make it. When re-assembling the hot end - leave the nozzle loose by 1/2 turn, shove the bowden tube back in down to the nozzle, put the lock clip on the tube fitting, and then do a final tighten on the nozzle. The hot end needs to be hot during that.
The problem could also be a fluctuation in the temperature, but that doesn't happen very often.
If you have a stock Creality extruder that is constructed of plastic then pull the pressure arm off and look at it's bottom side. Those arms WILL crack and fail at some point. The fix for that is an aluminum extruder.
Here comes Cura 5.9 and in this stable release we have lots of material and printer profiles for UltiMaker printers, including the newly released Sketch Sprint. Additionally, scarf seams have been introduced alongside even more print settings and improvements. Check out the rest of this article to find out the details on all of that and more
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
