I'm brand new to 3D printing. Just got me an Ender 5 Pro. After messing around for the last couple of days with bed leveling, I'm finally able to get consistent first level all thought I have to increase filament speed to 120 otherwise there are too many gaps in the base. Now I'm trying to work out issues printing this Calibration cube. My corners are being rounded too much and therefore size of cube differs. 20.02-20.08 mm when checking middle or when including corners goes to 20.50.

When I printed a full-sized model of an owl, it looks like it has stitching on the back. And random bumps all over.

  • $\begingroup$ I guess you mean 120 % flow modifier on the filament extrusion, not the speed. If so, you have incorrectly tried to modify the printer to solve a problem, while gaining a few other problems. First calibrate the filament extruder, then fix the first layer issues. E.g. the rounded corners and blobs in the owl are caused by overextrusion, so the 120 % flow modifier is completely incorrect and too high. $\endgroup$ – 0scar Dec 14 '19 at 11:45
